## Overview **web** **iOS** **API** Google Maps Platform is available for web (JS, TS), Android, and iOS, and also offers web services APIs for getting information about places, directions, and distances. The samples in this guide are written for one platform, but documentation links are provided for implementation on other platforms. When your users see your products online, they want to find the best and most convenient way to get their order. The Product Locator implementation guide and customization tips are what Google recommends as the optimal combination of Google Maps Platform APIs to build great product locator user experiences. Following this implementation guide, you can help customers see the detailed information they need to find your products, and give them directions to the store that has their item, whether they're driving, cycling, walking, or taking public transit. [![Product Locator system architecture connecting web browser, web server, inventory database, and Google Maps Platform APIs](https://developers.google.com/static/maps/architecture/product-locator/images/diagram.svg)](https://developers.google.com/static/maps/architecture/product-locator/images/diagram.svg) Architectural diagram (click to enlarge) ### Enable APIs To implement Product Locator, you must enable the following APIs in the Google Cloud console. The following hyperlinks send you to the Google Cloud console to enable each API for your selected project: - [Maps JavaScript API](https://console.cloud.google.com/apis/library/maps-backend.googleapis.com) - [Places API (New)](https://console.cloud.google.com/apis/library/places.googleapis.com) - [Geocoding API](https://console.cloud.google.com/apis/library/geocoding-backend.googleapis.com) - [Routes API](https://console.cloud.google.com/apis/library/routes.googleapis.com) For more information about setup, see [Getting started with Google Maps Platform](https://developers.google.com/maps/get-started). ### Implementation guide sections The following implementations and customizations are covered here:

See [Google Maps Platform solutions parameter](https://developers.google.com/maps/reporting-and-monitoring/reporting.md.txt#solutions-usage) for more information. ## Associate store locations with Google Maps Platform places ### Get place IDs |---|---| | **This example uses:** [Places API (New)](https://developers.google.com/maps/documentation/places/web-service/text-search.md.txt) | **Also available:** [JavaScript](https://developers.google.com/maps/documentation/javascript/place-search.md.txt) | You'll find that you have a database of your stores with basic information like the name of that location, its address, and its phone number, and you'd like to associate it with a place in Google Maps Platform as a set of final destinations your users can pick up products. To fetch the information that Google Maps Platform has about that place, including geographic coordinates and user-contributed information, find the [place ID](https://developers.google.com/maps/documentation/places/web-service/place-id.md.txt#id-overview) that corresponds to each of the stores in your database. You can make a call to the [Text Search (New) endpoint](https://developers.google.com/maps/documentation/places/web-service/text-search.md.txt) in Places API (New) and request only the `places.id` field in the field mask (which triggers the [Text Search Essentials IDs Only SKU](https://developers.google.com/maps/billing-and-pricing/sku-details/places#places_text-search-id-only-ess-sku)). The following shows an example of requesting the place ID for the Google London office: ``` curl -X POST -d '{ "textQuery" : "Google London" }' \ -H 'Content-Type: application/json' \ -H 'X-Goog-Api-Key: YOUR_API_KEY' \ -H 'X-Goog-FieldMask: places.id' \ 'https://places.googleapis.com/v1/places:searchText' ``` You can [store this place ID](https://developers.google.com/maps/documentation/places/web-service/place-id.md.txt#save-id) in your database with the rest of your store data and use it as an efficient way to request information about the store. Following are instructions for using the place ID to geocode, retrieve Place Details, and request directions to the place. ### Geocode your locations |---|---| | **This example uses:** [Geocoding API](https://developers.google.com/maps/documentation/geocoding) | **Also available:** [JavaScript](https://developers.google.com/maps/documentation/javascript/geocoding.md.txt) | If your database of stores has street addresses but not geographic coordinates, use the Geocoding API to obtain the latitude and longitude of that address for the purposes of calculating which stores are nearest to your customer. You can geocode the store on the server side, store the latitudes and longitudes in your database, and [refresh at least every 30 days](https://cloud.google.com/maps-platform/terms/maps-service-terms#3.-geocoding-api). Here is an example of using the Geocoding API to obtain the latitude and longitude of the place ID that was returned for the Google London office: ```html https://maps.googleapis.com/maps/api/geocode/json?place_id=ChIJVSZzVR8FdkgRTyQkxxLQmVU&key=YOUR_API_KEY&solution_channel=GMP_guides_productlocator_v1_a ``` ## Identify the user's location |---|---| | **This example uses:** [Place Autocomplete in the Maps JavaScript API](https://developers.google.com/maps/documentation/javascript/place-autocomplete-new.md.txt) | **Also available:** [Android](https://developers.google.com/maps/documentation/places/android-sdk/place-autocomplete.md.txt) \| [iOS](https://developers.google.com/maps/documentation/places/ios-sdk/place-autocomplete.md.txt) | A key component in Product Locator is identifying your user's starting location. You can offer two options for the user to specify their starting location: typing in the origin of their search, or granting permissions to web browser geolocation or mobile location services. ### Handle typed entries using autocomplete Today's users are accustomed to the autocomplete type-ahead functionality on the consumer version of Google Maps. This functionality can be integrated into any application using the Google Maps Platform Places libraries on mobile devices and the web. When a user types an address, autocomplete fills in the rest through the use of widgets. You can also provide your own autocomplete functionality using the [Place Autocomplete Data API](https://developers.google.com/maps/documentation/javascript/place-autocomplete-data) directly. [![Search input field displaying address autocomplete suggestions as a user types](https://developers.google.com/static/maps/architecture/product-locator/images/address-entry-2.png)](https://developers.google.com/static/maps/architecture/product-locator/images/address-entry-2.png) Address autocomplete functionality (click to enlarge) In the following example, add the Places and Marker libraries to your site by adding the `libraries=places,marker` parameter to the Maps JavaScript API script URL.

Next, add a container element to your page where the [`PlaceAutocompleteElement`](https://developers.google.com/maps/documentation/javascript/reference/places-widget.md.txt#PlaceAutocompleteElement) widget will be appended:

Finally, initialize the `PlaceAutocompleteElement` widget and append it to the container. Constraining the [Place Autocomplete predictions](https://developers.google.com/maps/documentation/javascript/place-autocomplete-new) with `includedPrimaryTypes: ["geocode"]` configures the widget to accept street addresses, neighborhoods, cities, and zip codes so users can input any level of specificity to describe their origin. When a user selects a prediction, the `gmp-select` event fires and you can call `place.fetchFields()` to request the `location` field containing the latitude and longitude of the user's origin. You'll use these map coordinates to indicate the relationship of your locations to the origin. ``` // Create the PlaceAutocompleteElement, restricting predictions to // geographical location types in the United Kingdom. const placeAutocomplete = new google.maps.places.PlaceAutocompleteElement({ includedPrimaryTypes: ["geocode"], includedRegionCodes: ["gb"], }); placeAutocomplete.placeholder = "Enter starting address, city, or zip code"; document.getElementById("autocomplete-container").appendChild(placeAutocomplete); // When the user selects an address from the drop-down, // fetch the place details and search for the nearest stores. placeAutocomplete.addEventListener("gmp-select", async ({ placePrediction }) => { const place = placePrediction.toPlace(); await place.fetchFields({ fields: ["id", "location", "formattedAddress"], }); searchFromOrigin(place); }); } ``` In this example, once the user selects the address, the `searchFromOrigin()` function starts. This takes the location of the matched result that is the user location, then searches for nearest locations based on those coordinates as the origin, discussed in the [Identify the closest stores](https://developers.google.com/maps/architecture/product-locator.md.txt#identify_stores) section. [![Product details view showing nearby store locations with stock availability and distance](https://developers.google.com/static/maps/architecture/product-locator/images/view-inventory-location-granted.png)](https://developers.google.com/static/maps/architecture/product-locator/images/view-inventory-location-granted.png) Show location options (click to enlarge) #### Expand this to see video walkthroughs of adding Place Autocomplete to your app: ### Website [Video](https://www.youtube.com/watch?v=c3MjU9E9buQ) ### Android apps [Video](https://www.youtube.com/watch?v=nDC-frkH_LA) ### iOS apps [Video](https://www.youtube.com/watch?v=MEuqZQ-_WfQ) ### Use browser geolocation To request and handle HTML5 browser geolocation, see how to [enable a **Use my location** window](https://developers.google.com/maps/documentation/javascript/geolocation.md.txt): [![Browser permission for user location](https://developers.google.com/static/maps/architecture/product-locator/images/location-permission.png)](https://developers.google.com/static/maps/architecture/product-locator/images/location-permission.png) Web browser permission request (click to enlarge) ## Identify the closest stores |---|---| | **This example uses:** [Routes Library, Maps JavaScript API](https://developers.google.com/maps/documentation/javascript/routes/get-a-route-matrix.md.txt) | **Also available:** [Routes API](https://developers.google.com/maps/documentation/routes/compute_route_matrix.md.txt) | Once you have the location of the user, you can compare this to where your store locations are. Doing this with the [`RouteMatrix` class](https://developers.google.com/maps/documentation/javascript/routes/route-matrix-class-overview) in the Routes Library, Maps JavaScript API (or the [Compute Route Matrix](https://developers.google.com/maps/documentation/routes/compute-route-matrix-over) feature in the Routes API) helps your users select the location that's most convenient for them by driving time or road distance. The standard way of organizing a list of locations is by sorting them by distance. Often this distance is calculated simply by using the straight line from a user to the location, but this can be misleading. The straight line might be over an impassable river or through busy roads at a time when another location might be more convenient. This is important when you have multiple locations within a few kilometers of each other. The `RouteMatrix.computeRouteMatrix` method works by taking a list of origin and destination locations and returning not only the travel distance but also the travel time between them. In a user's case, the origin would be where they currently are, or their desired starting point, and the destinations would be that of the locations. Origins and destinations can be specified as coordinate pairs, place IDs, or addresses. You can use `RouteMatrix.computeRouteMatrix` with routing preferences such as `TRAFFIC_AWARE` to show results based on current or future driving times. The following example calls `RouteMatrix.computeRouteMatrix` in the Routes Library, Maps JavaScript API, specifying the user's origin and up to 25 store locations at a time. ``` async function getDistances(originLocation) { const { RouteMatrix } = await google.maps.importLibrary("routes"); const request = { origins: [originLocation], destinations: stores.slice(0, 25).map((store) => store.location), travelMode: google.maps.TravelMode.DRIVING, routingPreference: "TRAFFIC_AWARE", fields: ["distanceMeters", "durationMillis", "condition"], }; return RouteMatrix.computeRouteMatrix(request); } function update(location) { if (!location) { return; } // ... // sort by spherical distance stores.sort((a, b) => { return ( google.maps.geometry.spherical.computeDistanceBetween( new google.maps.LatLng(a.location), location ) - google.maps.geometry.spherical.computeDistanceBetween( new google.maps.LatLng(b.location), location ) ); }); // display travel distance and time getDistances(location) .then(({ matrix }) => { const items = matrix.rows[0].items; for (let i = 0; i < items.length; i++) { if (items[i].condition === "ROUTE_EXISTS") { stores[i].travelDistance = items[i].distanceMeters; stores[i].travelDuration = items[i].durationMillis; } } }) .finally(() => { renderCards(stores); autocompleteInput.disabled = false; isUpdateInProgress = false; }); } ``` For each nearby location you can display stock status of the product based on your inventory database. ## Display store information |---|---| | **This example uses:** [Places Library, Maps JavaScript API](https://developers.google.com/maps/documentation/javascript/place-details.md.txt) | **Also available:** [Places SDK for Android](https://developers.google.com/maps/documentation/places/android-sdk/details-place.md.txt) \| [Places SDK for iOS](https://developers.google.com/maps/documentation/places/ios-sdk/details-place.md.txt) \| [Places API (New)](https://developers.google.com/maps/documentation/places/web-service/place-details.md.txt) | You can share rich Place Details like contact information, hours of operation, and current open status to help customers pick their preferred location or finalize their order. After making a call to the [Maps JavaScript API to get Place Details](https://developers.google.com/maps/documentation/javascript/place-details), you can filter and render the response. [![Nearby store options displaying product stock status, opening hours, and travel distance](https://developers.google.com/static/maps/architecture/product-locator/images/view-inventory-location-granted.png)](https://developers.google.com/static/maps/architecture/product-locator/images/view-inventory-location-granted.png) Show store options (click to enlarge) To request Place Details, you'll need the place ID of each of your locations. See [Get place IDs](https://developers.google.com/maps/architecture/product-locator.md.txt#match_location_data) to retrieve the place ID of your location. The following Place Details request uses the [Place class](https://developers.google.com/maps/documentation/javascript/place.md.txt) to return the name, coordinates, website, phone number, rating, and hours for the Google London place ID:
``` const place = new google.maps.places.Place({ id: 'ChIJVSZzVR8FdkgRTyQkxxLQmVU', }); await place.fetchFields({ fields: [ 'displayName', 'nationalPhoneNumber', 'location', 'regularOpeningHours', 'rating', 'utcOffsetMinutes', 'websiteURI', ], }); createMarker(place); ``` *** ** * ** ***
## Enhance Product Locator Depending on your business or users' needs, you can further enhance the user's experience. ## Provide navigation directions |---|---| | **This example uses:** [Routes Library, Maps JavaScript API](https://developers.google.com/maps/documentation/javascript/routes/get-a-route.md.txt) | **Also available:** [Routes API](https://developers.google.com/maps/documentation/routes/compute_route_directions.md.txt) web service for use on Android and iOS, either directly from the application or remotely through a server proxy | When you show users directions from within your site or applications, your users don't need to navigate away from your site and get distracted with other pages or see competitors on the map. With the Routes API, you can also request [eco-friendly routes](https://developers.google.com/maps/documentation/routes/eco-routes) to estimate fuel or energy usage and show the environmental impact of a journey. The [`Route` class](https://developers.google.com/maps/documentation/javascript/routes/route-class-overview) in the Routes Library, Maps JavaScript API also has methods such as `createPolylines()` and `createWaypointAdvancedMarkers()` that let you process the results and display them on a map. Following is an example of requesting and displaying a route on a map. For more information on the sample, see [Get a route](https://developers.google.com/maps/documentation/javascript/routes/get-a-route.md.txt). ## Send directions to mobile To make it even easier for users to reach a location, you can text or email them a directions link. When they click it, the Google Maps app will launch on their phone if it is installed, or maps.google.com will load in their device's web browser. Both of these experiences provide the user with the option to use turn-by-turn navigation, including voice guidance, to reach the destination. Use [Maps URLs](https://developers.google.com/maps/documentation/urls/get-started.md.txt#directions-action) to compose a directions URL like the following, with the URL-encoded place name as the `destination` parameter and place ID as the `destination_place_id` parameter. There is no cost to compose or use Maps URLs, so you don't need to include an API key in the URL. ``` https://www.google.com/maps/dir/?api=1&destination=Google%20London&destination_place_id=ChIJVSZzVR8FdkgRTyQkxxLQmVU ``` You can optionally provide an `origin` query parameter using the same address format as the destination. But by omitting it, the directions start from the user's current location, which may be different from where they were using your Product Locator app. [Maps URLs](https://developers.google.com/maps/documentation/urls/get-started.md.txt#parameters_1) provide additional query parameter options, such as `travelmode` and `dir_action=navigate` to launch the directions with navigation turned on. [This clickable link](https://www.google.com/maps/dir/?origin=Tottenham+Hotspur+Stadium+High+Road+London+UK&api=1&destination=Google+London&destination_place_id=ChIJVSZzVR8FdkgRTyQkxxLQmVU&travelmode=transit), which extends the preceding example URL, sets the `origin` as a London football stadium and uses `travelmode=transit` to provide public transit directions to the destination. To send a text or email containing this URL, we currently recommend using a third-party application such as [twilio](https://www.twilio.com/). If you're using App Engine, you can use third-party companies to send SMS messages or email. For more information, see [Sending Messages with Third-Party Services](https://cloud.google.com/appengine/docs/standard/php/mail/sending-messages). ## Show your locations on an interactive map ### Use dynamic maps |---|---| | **This example uses:** [Maps JavaScript API](https://developers.google.com/maps/documentation/javascript) | **Also available:** [Android](https://developers.google.com/maps/documentation/android-sdk/map.md.txt) \| [iOS](https://developers.google.com/maps/documentation/ios-sdk/map.md.txt) | A locator is an important part of the user experience. Some sites, however, may lack even a simple map, requiring users to leave the site or the app to find a nearby location. This means a suboptimal experience for users who must navigate between pages in order to get the information they require. Instead, you can enhance this experience by embedding and customizing maps into your applications. Adding a dynamic map to your page---that is, a map that users can move around, zoom in and out on, and get details about different locations and points of interest---can be done with a few lines of code. First, you need to include the Maps JavaScript API in the page. This is done through linking the following script in your HTML page, including `libraries=marker` so you can add [advanced markers](https://developers.google.com/maps/documentation/javascript/advanced-markers/overview) to the map. The URL references the JavaScript `initMap` function that runs when the page loads. In the URL, you can also define the language or region of your map to make sure it's formatted in the correct way for the specific country you're targeting. Setting a region also ensures that the behavior of apps used outside of the United States is biased towards the region you set. View the [Google Maps Platform Coverage Details](https://developers.google.com/maps/coverage.md.txt) for a full list of supported languages and regions, and learn more about [`region` parameter usage.](https://developers.google.com/maps/documentation/javascript/localization#Region) Next, you need an HTML `div` to place your map on the page. This is the place where the map will be displayed.

The next step is to set the basic functionality of your map. This is done in the `initMap` script function specified in the script URL. In this script, shown in the following example, you can set the initial location, a [map ID](https://developers.google.com/maps/documentation/javascript/map-ids/mapid-over.md.txt) (required for advanced markers and cloud-based map styling), [the type of map](https://developers.google.com/maps/documentation/javascript/maptypes.md.txt), and which controls are available on the map for your users. Notice that `getElementById()` references the preceding "map" `div` ID.
``` function initMap() { const map = new google.maps.Map(document.getElementById("map"), { zoom: 12, center: { lat: 51.485925, lng: -0.129500 }, mapId: "DEMO_MAP_ID", zoomControl: false }); } ```
For a locator, you're usually interested in setting the initial location, the center point or bounds, and the zoom level (how much the map is zoomed into that location). Most other elements, such as tuning of controls, are optional as you determine the level of interaction with the map. ### Customize your map You can change your map's appearance and details in a number of ways. For example, you can: - Create your own custom markers to replace the default map pins. - Change the colors of map features to reflect your brand. - Control which points of interest you display (attractions, food, lodging, and so on) and at what density, letting you focus user attention on your locations while highlighting the landmarks that help users get to the nearest location. ### Create custom map markers You can customize your [advanced markers](https://developers.google.com/maps/documentation/javascript/advanced-markers/basic-customization) by changing the default pin background, border, or glyph color (for example, to indicate whether a location is currently open), replacing the marker with a [custom graphic image](https://developers.google.com/maps/documentation/javascript/advanced-markers/graphic-markers) such as the logo of your brand, or building [custom HTML and CSS markers](https://developers.google.com/maps/documentation/javascript/advanced-markers/html-markers). Info windows, or pop-up windows, can provide additional information to users, such as opening hours, phone number, or photos. Following is a sample map that uses custom graphic markers. (See the source code in the [Maps JavaScript API custom graphic markers topic](https://developers.google.com/maps/documentation/javascript/advanced-markers/graphic-markers.md.txt).) For detailed information, see the advanced markers documentation for [JavaScript (web)](https://developers.google.com/maps/documentation/javascript/advanced-markers/overview), [Android](https://developers.google.com/maps/documentation/android-sdk/advanced-markers/overview.md.txt), and [iOS](https://developers.google.com/maps/documentation/ios-sdk/advanced-markers/overview.md.txt). ### Style your map Google Maps Platform lets you style your map in ways that help users find the closest location, get there as quickly as possible, and help you reinforce your brand. For example, you can change map colors to match your branding, and you can reduce distractions on the map by controlling the points of interest that are visible to users. Google Maps Platform also provides a number of map starter templates, some of which are optimized for different industries, such as travel, logistics, real estate, and retail. You can create or modify map styles in the Google Cloud console [Map Styles](https://console.cloud.google.com/project/_/google/maps-apis/studio/styles) page in your project. #### Expand to see animations of map style creation and styling in the Cloud console: ### Industry map styles This animation shows predefined industry-specific map styles you can use. These styles provide an optimal starting point for each type of industry. For example, the Retail map style reduces points of interest on the map, letting users focus on your locations, as well as the landmarks to help them get to the closest location as quickly and confidently as possible. ![On the Map Style page, the mouse clicks Create New Map Style. On the New Map Style page, the mouse clicks the radio button next to each of the following industry optimized styles: Travel, Logistics, Real Estate, and Retail. As each button is clicked, the map style description and graphical preview changes.](https://developers.google.com/static/maps/architecture/store-locator/images/ioms_animation.gif) ### Points of interest control This animation sets the marker color for points of interest and increases the POI density on the map style. The higher the density, the more POI markers appear on the map. ![On the Map Style page, the mouse clicks Create New Map Style. On the New Map Style page, under Create Your Own Style, the Google Map radio button is selected. The mouse clicks the Atlas radio button for the Atlas style, then clicks Open in Style Editor. In the Style Editor, the mouse clicks the Points of Interest feature, then clicks the Icon element, setting the color to red. The mouse then selects the POI Density checkbox and slides the density control to the right for maximum density. More and more red markers appear on the map preview as density increases. The mouse then moves to the Save button.](https://developers.google.com/static/maps/architecture/store-locator/images/poi_animation.gif) Each map style has its own ID. After you publish a style in the Cloud console, you reference that map ID in your code---which means you can update a map style in real time without refactoring your app. The new look will automatically appear in the existing application and be used across platforms. The following examples show how to add a map ID to a web page using the Maps JavaScript API. By including one or more `map_ids` in the script URL, the Maps JavaScript API automatically makes those styles available for faster map rendering when you call those styles in your code. ```html ``` The following code displays a styled map on the web page. (Not shown is an HTML `
` element where the map will appear on the page.) ``` map = new google.maps.Map(document.getElementById('map'), { center: {lat: 51.485925, lng: -0.129500}, zoom: 12, mapId: '1234abcd5678efgh' }); ``` Learn more about incorporating cloud-based maps styling in [JavaScript (web)](https://developers.google.com/maps/documentation/javascript/cloud-based-map-styling), [Android](https://developers.google.com/maps/documentation/android-sdk/cloud-based-map-styling), and [iOS](https://developers.google.com/maps/documentation/ios-sdk/cloud-based-map-styling). ## Combine custom location data with Place Details The previous [Show your locations on an interactive map](https://developers.google.com/maps/architecture/product-locator.md.txt#show_locations) section describes using Place Details to give users a rich level of information about your locations, such as opening hours, photos, and reviews. It's helpful to understand the [pricing and SKU tiers of different data fields](https://developers.google.com/maps/documentation/places/web-service/data-fields) in Places API (New). To manage your costs, one strategy is to combine the information you already have about your locations with the fresh information from Google Maps such as temporary closure, holiday hours, and user ratings, photos, and reviews. If you already have the contact information for your stores, you won't need to request those fields from Place Details and can constrain your field mask to fetch only the fields you want to display. You may have your own place data to supplement or use instead of Place Details. The [codelab](https://developers.google.com/codelabs/maps-platform/full-stack-store-locator) for the full-stack locator provides an example of using GeoJSON with a database to store and retrieve your own location details.
