> [!WARNING]
> **Warning:** This page is for legacy offline conversion imports and **only** meant for users who are unable to implement [enhanced conversions for leads](https://developers.google.com/google-ads/api/docs/conversions/upload-offline).

You can use the Google Ads API to upload [offline click conversions](https://support.google.com/google-ads/answer/7014069) into
Google Ads in order to track ads that led to sales in the offline world, such as
over the phone or through a sales rep.

## Setup

There are a few prerequisites to a working offline conversions setup. Make sure
all of the prerequisites are satisfied before proceeding to implementation:

1. Enable conversion tracking in your Google Ads conversion customer.

2. Configure tagging and store click IDs.

### 1. Enable conversion tracking in your Google Ads conversion customer

If you completed the conversions [getting started guide](https://developers.google.com/google-ads/api/docs/conversions/getting-started) and
have conversion tracking enabled, you can skip to
[step two: configure tagging](https://developers.google.com/google-ads/api/docs/conversions/legacy_oci_guide#configure_tagging).

#### Retrieve information about your conversion tracking setup

You can check your account's conversion tracking setup and confirm conversion
tracking is enabled by querying the [`Customer`](https://developers.google.com/google-ads/api/fields/v26/customer) resource
for the
[`ConversionTrackingSetting`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionTrackingSetting).
Issue the following query with
[`GoogleAdsService.SearchStream`](https://developers.google.com/google-ads/api/reference/rpc/v26/GoogleAdsService/SearchStream):

    SELECT
      customer.conversion_tracking_setting.google_ads_conversion_customer,
      customer.conversion_tracking_setting.conversion_tracking_status,
      customer.conversion_tracking_setting.conversion_tracking_id,
      customer.conversion_tracking_setting.cross_account_conversion_tracking_id
    FROM customer

The `google_ads_conversion_customer` field indicates the Google Ads account that
creates and manages conversions for this customer. For customers using
[cross-account conversion
tracking](https://support.google.com/google-ads/answer/3030657), this is the ID
of a manager account. The Google Ads conversion customer ID should be given as the
`customer_id` in Google Ads API requests to create and manage conversions. Note that
this field is populated even if conversion tracking is not enabled.

The
[`conversion_tracking_status`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionTrackingStatusEnum.ConversionTrackingStatus)
field indicates whether conversion tracking is enabled and whether the account
is using cross-account conversion tracking.

#### Create a conversion action under the Google Ads conversion customer

If the `conversion_tracking_status` value is `NOT_CONVERSION_TRACKED`,
conversion tracking is not enabled for the account. Enable conversion tracking
by creating at least one [`ConversionAction`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAction) in
the Google Ads conversion account, like in the following example. Alternatively, you
can create a conversion action in the UI by following the instructions in the
[Google Ads Help Center article on conversion tracking
setup](https://support.google.com/google-ads/answer/1722054#choose) for the
conversion type you want to enable.

Note that enhanced conversions are enabled automatically when sent through the
Google Ads API, but they can be disabled through the Google Ads UI.

> [!IMPORTANT]
> **Important:** For offline conversions using click IDs, the [`type`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAction#type) field must be `UPLOAD_CLICKS`. We recommend also setting the [`category`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAction#category) field ([`ConversionActionCategory`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionActionCategoryEnum.ConversionActionCategory)) to the category that best describes your conversions. Update the code example that follows so that the `type` and `category` fields are correct for the type you're implementing.

#### Code example

### Java

```java
private void runExample(GoogleAdsClient googleAdsClient, long customerId) {

  // Creates a ConversionAction.
  ConversionAction conversionAction =
      ConversionAction.newBuilder()
          // Note that conversion action names must be unique. If a conversion action already
          // exists with the specified conversion_action_name the create operation will fail with
          // a ConversionActionError.DUPLICATE_NAME error.
          .setName("Earth to Mars Cruises Conversion #" + getPrintableDateTime())
          .setCategory(ConversionActionCategory.DEFAULT)
          .setType(ConversionActionType.WEBPAGE)
          .setStatus(ConversionActionStatus.ENABLED)
          .setViewThroughLookbackWindowDays(15L)
          .setValueSettings(
              ValueSettings.newBuilder()
                  .setDefaultValue(23.41)
                  .setAlwaysUseDefaultValue(true)
                  .build())
          .build();

  // Creates the operation.
  ConversionActionOperation operation =
      ConversionActionOperation.newBuilder().setCreate(conversionAction).build();

  try (ConversionActionServiceClient conversionActionServiceClient =
      googleAdsClient.getLatestVersion().createConversionActionServiceClient()) {
    MutateConversionActionsResponse response =
        conversionActionServiceClient.mutateConversionActions(
            Long.toString(customerId), Collections.singletonList(operation));
    System.out.printf("Added %d conversion actions:%n", response.getResultsCount());
    for (MutateConversionActionResult result : response.getResultsList()) {
      System.out.printf(
          "New conversion action added with resource name: '%s'%n", result.getResourceName());
    }
  }
}
      
```

### C#

    // If a conversion action already exists with the specified name the create operation
    // will fail with a ConversionAction.DUPLICATE_NAME error.
    string ConversionActionName = "Earth to Mars Cruises Conversion #"

            AlwaysUseDefaultValue = true
        }
    };

    // Create the operation.
    ConversionActionOperation operation = new ConversionActionOperation()
    {
        Create = conversionAction
    };

    try
    {
        // Create the conversion action.
        MutateConversionActionsResponse response =
            conversionActionService.MutateConversionActions(customerId.ToString(),
                    new ConversionActionOperation[] { operation });

        // Display the results.
        foreach (MutateConversionActionResult newConversionAction in response.Results)
        {
            Console.WriteLine($"New conversion action with resource name = " +
                $"'{newConversionAction.ResourceName}' was added.");

Make sure the [`type`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAction#type)
is set to the correct
[`ConversionActionType`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionActionTypeEnum.ConversionActionType)
value. For more guidance on creating conversion actions in the Google Ads API, see
[Create
conversion actions](https://developers.google.com/google-ads/api/docs/conversions/getting-started#create-conversion-actions).

#### Retrieve an existing conversion action

You can retrieve details for an existing conversion action by issuing the
following query. Make sure the customer ID in the request is set to the Google Ads
conversion customer you identified earlier, and the conversion action type is
set to the correct
[`ConversionActionType`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionActionTypeEnum.ConversionActionType)
value.

    SELECT
      conversion_action.id,
      conversion_action.resource_name,
      conversion_action.name,
      conversion_action.type,
      conversion_action.category,
      conversion_action.status
    FROM conversion_action

    WHERE conversion_action.type = 'UPLOAD_CLICKS'

### 2. Configure tagging and store click IDs

> [!NOTE]
> **Note:** You can [upload enhanced conversions for leads](https://developers.google.com/google-ads/api/docs/conversions/upload-offline) without having captured GCLIDs.

Follow the [autotagging instructions](https://support.google.com/google-ads/answer/1752125#how_to_check_auto_tagging) to confirm autotagging is
enabled. Set up your Google Ads account, website, and lead-tracking system to
capture and store the GCLID for each impression, as well as the GBRAID or
WBRAID URL parameters for your ads. Autotagging is turned on by default for new
accounts.

## Construct the request

Follow this guidance to construct your
[`UploadClickConversionsRequest`](https://developers.google.com/google-ads/api/reference/rpc/v26/UploadClickConversionsRequest) and set its
fields to appropriate values.

`customer_id`

:   Identifies the Google Ads account of your upload. Set this to the
    [Google Ads conversion customer](https://developers.google.com/google-ads/api/docs/conversions/getting-started#conversion_tracking_setup) of the account that is
    the source of the clicks.


`job_id`

:   Provides a mechanism for associating your upload requests with the per-job
    information in [offline data diagnostics](https://developers.google.com/google-ads/api/docs/conversions/upload-summaries).

    If you don't set this field, the Google Ads API assigns each request a unique value
    in the range of `[2^31, 2^63)`. If you would prefer to group multiple requests
    into a single logical job, set this field to the same value in the range
    `[1, 2^31)` on every request in your job.

    The `job_id` in the [response](https://developers.google.com/google-ads/api/reference/rpc/v26/UploadClickConversionsResponse) contains the
    job ID for the request, regardless of whether you specified a value or let the
    Google Ads API assign a value.

`partial_failure`

:   Determines how the Google Ads API handles errors from operations.

    This field must be set to `true`. Follow the
    [partial failures guidelines](https://developers.google.com/google-ads/api/docs/best-practices/partial-failures) when processing the response.

## Create click conversion operations

The collection of [`ClickConversion`](https://developers.google.com/google-ads/api/reference/rpc/v26/ClickConversion) objects in your
`UploadClickConversionsRequest` defines the set of conversions you want to
upload. Follow this guidance to construct each `ClickConversion` and set its
fields to appropriate values.

### Set the required fields of each conversion operation

Follow these instructions to set the required fields of `ClickConversion`
to appropriate values.

`gclid`, `gbraid`, `wbraid`

:   The GCLID or URL parameters that you capture when a user lands on your
    website or app after an ad click. At least one of the following fields is
    required:

    - `gclid`
    - `gbraid`
    - `wbraid`

    Include every click identifier that you captured for a conversion on the same
    `ClickConversion` object. When more than one identifier is present, Google Ads
    uses them in the following order of precedence: `gclid`, then `wbraid`, then
    `gbraid`.

`conversion_date_time`

:   The date and time of the conversion.

    The value must have a timezone specified, and the format must be

    `yyyy-mm-dd HH:mm:ss+|-HH:mm`, for example: `2022-01-01 19:32:45-05:00` (ignoring daylight saving time)
    .

    The timezone can be for any valid value: it does *not* have to match the
    account's timezone. However, if you plan on comparing your uploaded
    conversion data with those in the Google Ads UI, we recommend using the same
    timezone as your Google Ads account so that the conversion counts match.
    You can find more details and examples in
    [Prepare your data for import](https://support.google.com/google-ads/answer/7014069#prepare_data) and check
    [Codes and formats](https://developers.google.com/google-ads/api/data/codes-formats#timezone_ids) for a list of valid timezone IDs.

    > [!NOTE]
    > **Note:** If you're uploading conversions for [Commissions (pay-per-conversion) for Hotel ads](https://support.google.com/google-ads/answer/9243945), you can only upload conversions for clicks that occurred in the same month. Conversions uploaded after 4 AM Pacific Time (PT) on the first day of the following month of when the click happened are ignored.

`user_identifiers`

:   Don't set this field when uploading conversions using only click IDs. If this
    field is set, Google Ads treats the upload operation as an upload for
    [enhanced conversions for leads](https://developers.google.com/google-ads/api/docs/conversions/upload-offline).

`conversion_action`

:   The resource name of the [`ConversionAction`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAction) for the click
    conversion.

    The conversion action must have a `type` of `UPLOAD_CLICKS`, and must exist
    in the Google Ads conversion customer of the Google Ads account associated with the
    click.

`conversion_value`

:   The value of the conversion.

`currency_code`

:   The [currency code](https://developers.google.com/google-ads/api/data/codes-formats#currency_codes) of the `conversion_value`.

### Set optional fields of each conversion operation

Review the following list of optional fields and set them on your
`ClickConversion` as needed.

`order_id`
:   The transaction ID for the conversion. This field is optional but strongly
    recommended. If you set it during the upload, you *must* use it for any
    [adjustments](https://developers.google.com/google-ads/api/docs/conversions/upload-adjustments) made to the conversion. To learn more about
    how to use a transaction ID to minimize duplicate conversions, see
    [Use a transaction ID to minimize duplicate conversions](https://support.google.com/google-ads/answer/6386790).

`external_attribution_data`

:   If you use third-party tools or homegrown solutions to track conversions, then
    you may want to give Google Ads only part of the credit for the conversion, or you
    may want to distribute the credit for a conversion across multiple clicks.
    [Externally attributed conversion imports](https://support.google.com/google-ads/answer/7014069#external_attributed_conversions&zippy=%2Cexternally-attributed-conversions) allow you
    to upload conversions with fractional credit assigned to each click.

    To upload fractional credits, set this field to an
    [`ExternalAttributionData`](https://developers.google.com/google-ads/api/reference/rpc/v26/ExternalAttributionData) object with values for
    `external_attribution_model` and `external_attribution_credit`.

`custom_variables`

:   The values for [custom conversion variables](https://developers.google.com/google-ads/api/docs/conversions/conversion-custom-variables).

    Google Ads does not support custom conversion variables when `wbraid` or `gbraid`
    is used without a `gclid`.

`cart_data`

:   You can include [shopping cart data](https://support.google.com/google-ads/answer/9028254) for a `ClickConversion` in
    the [`cart_data`](https://developers.google.com/google-ads/api/reference/rpc/v26/ClickConversion#cart_data) field, which consists of the
    following attributes:

    - `merchant_id`: The ID of the associated [Merchant Center](https://support.google.com/google-ads/answer/188493) account.
    - `feed_country_code`: The ISO 3166 two-character [region code](https://developers.google.com/google-ads/api/data/codes-formats#country_codes) of the Merchant Center feed.
    - `feed_language_code`: The ISO 639-1 [language code](https://developers.google.com/google-ads/api/data/codes-formats#languages) of the Merchant Center feed.
    - `local_transaction_cost`: The sum of all transaction-level discounts, in the `currency_code` of the `ClickConversion`.
    - `items`: The items in the shopping cart.

    Each item in `items` consists of the following attributes:

    - `product_id`: The [product ID](https://support.google.com/merchants/answer/6324405), sometimes referred to as the offer ID or item ID.
    - `quantity`: The quantity of the item.
    - `unit_price`: The unit price of the item.

    Google Ads does not support `cart_data` when `wbraid` or `gbraid` is used without
    a `gclid`.

`conversion_environment`

:   Indicates the environment where this conversion was recorded. For example, App
    or Web.

## Troubleshoot

[Offline data diagnostics](https://developers.google.com/google-ads/api/docs/conversions/upload-summaries) provide a single resource for
reviewing the overall health of your uploads on an ongoing basis. However,
during implementation you can use the information in this section to investigate
any errors reported in the [`partial_failure_error`](https://developers.google.com/google-ads/api/reference/rpc/v26/UploadClickConversionsResponse#partial_failure_error)
field of the response.

Some of the most common errors when uploading conversion actions are
authorization errors, such as `USER_PERMISSION_DENIED`. Double check that you
have the customer ID in your request set to the Google Ads conversion customer
which owns the conversion action. Visit our
[authorization guide](https://developers.google.com/google-ads/api/docs/oauth/overview) for more details and see our
[common errors guide](https://developers.google.com/google-ads/api/docs/common-errors#authorizationerror) for tips on how to debug these different
errors.

### Debug common errors

| Error ||
|---|---|
| [`INVALID_CONVERSION_ACTION_TYPE`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadErrorEnum.ConversionUploadError#invalid_conversion_action_type) | The specified conversion action has a [type](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionActionTypeEnum.ConversionActionType) that is not valid for uploading click conversions. Make sure the `ConversionAction` specified in your upload request has type `UPLOAD_CLICKS`. |
| [`NO_CONVERSION_ACTION_FOUND`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadErrorEnum.ConversionUploadError#no_conversion_action_found) | The specified conversion action is either not enabled or cannot be found within the uploading `customer_id`. [Retrieve information about your conversion setup](https://developers.google.com/google-ads/api/docs/conversions/getting-started#conversion_tracking_setup) to make sure the conversion action in your upload is enabled and is owned by the `customer_id` of the upload request. |
| [`TOO_RECENT_CONVERSION_ACTION`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadErrorEnum.ConversionUploadError#too_recent_conversion_action) | The conversion action is newly created. Wait at least 6 hours after the action is created before retrying the failed conversions. |
| [`INVALID_CUSTOMER_FOR_CLICK`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadErrorEnum.ConversionUploadError#invalid_customer_for_click) | The `customer_id` of the request is not the same customer ID that was the [Google Ads API conversion account](https://developers.google.com/google-ads/api/docs/conversions/getting-started) at the time of the click. Update the `customer_id` of the request to the correct customer. |
| [`EVENT_NOT_FOUND`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadErrorEnum.ConversionUploadError#event_not_found) | Google Ads cannot find the combination of click ID and `customer_id`. Review the [requirements for `customer_id`](https://developers.google.com/google-ads/api/docs/conversions/upload-offline#construct-the-request) and confirm you are uploading using the correct Google Ads account. |
| [`DUPLICATE_CLICK_CONVERSION_IN_REQUEST`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadErrorEnum.ConversionUploadError#duplicate_click_conversion_in_request) | Multiple conversions in the request have the same combination of click ID, `conversion_date_time`, and `conversion_action`. Remove duplicate conversions from your request. |
| [`CLICK_CONVERSION_ALREADY_EXISTS`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadErrorEnum.ConversionUploadError#click_conversion_already_exists) | A conversion with the same combination of click ID, `conversion_date_time`, and `conversion_action` was previously uploaded. Ignore this error if you were retrying the upload and this conversion previously succeeded. If you want to add another conversion in addition to the previously uploaded conversion, adjust the `conversion_date_time` of the `ClickConversion` to avoid duplicating the previously uploaded conversion. |
| [`EXPIRED_EVENT`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadErrorEnum.ConversionUploadError#expired_event) | The imported click occurred before the timeframe specified in the `click_through_lookback_window_days` field. A change to the `click_through_lookback_window_days` [only impacts clicks recorded after the change](https://support.google.com/google-ads/answer/3123169), so changing the lookback window wouldn't resolve this error for the particular click. If appropriate, change the `conversion_action` to another action with a longer lookback window. |
| [`CONVERSION_PRECEDES_EVENT`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadErrorEnum.ConversionUploadError#conversion_precedes_event) | The `conversion_date_time` is before the date and time of the click. Update the `conversion_date_time` to a later value. |
| [`VALUE_MUST_BE_UNSET`](https://developers.google.com/google-ads/api/reference/rpc/v26/FieldErrorEnum.FieldError#value_must_be_unset) | The `ClickConversion` has a value set for either `gbraid` or `wbraid` (without a `gclid`) and has a value for `custom_variables` or `cart_data`, which Google Ads does not support with `gbraid` or `wbraid`. Unset the conflicting field. > [!NOTE] > **Note:** If a conversion sets both `gbraid` and `wbraid` and also fails another field validation check on the same conversion, the API can return [`GBRAID_WBRAID_BOTH_SET`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadErrorEnum.ConversionUploadError#gbraid_wbraid_both_set). Fix the other validation issue on the conversion. You do not need to remove click identifiers. |

## Conversions in reports

Uploaded conversions are reflected in reports for the
[**impression** date of the original click](https://support.google.com/google-ads/answer/13321563#Date_range_reporting_date&zippy=%2Cdifferences-in-date-range-and-reporting-date), not the date of
the upload request or the date of the `conversion_date_time` of the
[`ClickConversion`](https://developers.google.com/google-ads/api/reference/rpc/v26/ClickConversion).

It takes up to 3 hours for imported conversion statistics to appear in your
Google Ads account for last-click attribution. For other search attribution models,
it can take longer than 3 hours. Consult the
[data freshness guide](https://support.google.com/google-ads/answer/2544985) for more information.
