Send messages

RBM agents communicate with users by sending and receiving messages. To send messages to users, your agent sends message requests to the RCS Business Messaging API. A single request can include text, rich cards, media and PDF files, as well as suggested replies and suggested actions.

The RBM platform will return errors in certain situations to help you manage message delivery:

• If you send a message to a user whose device doesn't support RCS or doesn't have RCS enabled, the RBM platform returns a 404 NOT_FOUND error. In this case, you can attempt to reach the user through the fallback methods defined in your infrastructure.
• If you send a message to an RCS user on a network where your agent isn't launched yet, or on a network that hasn't enabled RCS traffic, the RBM platform returns a 404 NOT_FOUND error.
• If you send a message with features that a user's device doesn't support, the RBM platform returns 400 INVALID_ARGUMENT error and doesn't deliver your message.

As part of your multi-channel messaging strategy, it's best to revoke messages that aren't delivered after a reasonable time and send them through a different channel. To revoke messages automatically at a predefined time, set a message expiration.

Recipient is offline

The RBM platform still accepts a message for delivery if the recipient is offline. You receive a 200 OK response, and the RBM platform holds the message and attempts redelivery for 30 days. There's no need to ask RBM to send the message again.

RBM deletes any undelivered messages 30 days after they were submitted.

Depending on your agent's use case, you might want to revoke an undelivered message before this 30-day timeout. Revocation can prevent offline users from receiving an outdated message when they come back online. There are multiple ways to revoke a message:

• Send a revocation request to trigger the revocation.
• Set a message expiration to automatically revoke the message at the appropriate time.

Set a message expiration

Is your agent's message time sensitive? For example, OTPs are only valid for a brief period. Limited-time offers expire. And appointment reminders aren't relevant after the appointment date. To help ensure timely and relevant messages, set a message expiration. This can prevent offline users from receiving stale content when they come back online. Expiration is also a good cue to invoke your fallback messaging strategy so users get the info they need on time.

To set a message expiration, specify one of the following fields in the agent message:

• expireTime: the exact time in UTC when the message expires.
• ttl(time to live): the amount of time before the message expires.

For formatting and value options, see AgentMessage.

Once the message expires, the RBM platform stops trying to deliver the message, and it's automatically revoked. However, this could fail on rare occasions. For example, the API could trigger the revocation while the RBM platform was in the process of delivering the message. To confirm whether or not the expired message was successfully revoked, RBM will send a notification event to your webhook.

The maximum value for ttl and expireTime is 15 days after message submission.

Set the message traffic type

The RBM API includes a messageTrafficType field to categorize messages. While agent use cases still define agent behavior and which business rules apply, messageTrafficType allows for more detailed categorization of message content. Ultimately, this will make it possible for a single agent to handle multiple use cases. There's no impact to existing agent use cases or business rules at this time.

Currently, this field is optional, but it's recommended that you set it now so you don't receive an error when the field becomes required.

To set the message traffic type, assign the appropriate messageTrafficType for each message based on its content. RBM supports the following traffic types.

Traffic type	Message content	Agent use case
AUTHENTICATION	For authentication messages.	OTP
TRANSACTION	For messages about a user's existing services or products. For example: confirmations, payment receipts, or booking details.	Transactional or Multi-use
PROMOTION	For promotional messages like offers, discounts, announcements, or other promotional content.	Promotional or Multi-use
SERVICEREQUEST	For messages about services that the user has explicitly requested.	OTP, Transactional, Promotional, or Multi-use
ACKNOWLEDGEMENT	For messages used to acknowledge a user's action – specifically an unsubscribe request. This confirms that the user's request was received and is being processed.	OTP, Transactional, Promotional, or Multi-use

If no traffic type is set, the system assigns the default type for the agent's use case.

Agent use case	Default traffic type
OTP	AUTHENTICATION
Transactional	TRANSACTION
Promotional	PROMOTION
Multi-use	MESSAGE_TRAFFIC_TYPE_UNSPECIFIED

Multi-use agents have no default traffic type. You must set the traffic type explicitly for each message based on its content. If you don't replace the MESSAGE_TRAFFIC_TYPE_UNSPECIFIED value, an error will result.

Message size limits

The maximum size of the entire stringified AgentMessage is 250 KB. The text portion of the message has its own limit of 3072 characters.

The maximum size of a file that can be sent through RBM is 100MB. Refer to Media and PDF files for more information.

Important: For RBM traffic in the US: To prevent unexpected data consumption for users in the United States, the total combined size of all media and PDF attachments within a single RBM message sent to a US phone number must not exceed 100 MiB. (1 MiB = 1,048,576 bytes). This limit applies exclusively to RBM traffic on US carriers. For example, if an agent operates in multiple countries, such as Canada and the US, this limit only affects messages sent to US numbers.

Text

The simplest messages are made of text. Text messages are best suited to communicate information without the need for visuals, complex interaction, or response.

Example

The following code sends a plain text message. For formatting and value options, see phones.agentMessages.create.

Basic Message content - conversion of SMS

Carriers have introduced billing models to support the move of SMS messages to RBM. An RBM message containing up to 160 UTF-8 characters is called a Basic Message.

When constructing a request to send a Basic Message, remember that characters are counted as 1 byte (UTF-8). If you send a message containing special characters such as emoji or a multi-byte character set, each character counts as 2-4 UTF-8 characters or more.

Enter some text in the box to check its length:

Basic Message content and link previews

RCS clients may implement link previews. If a text-only RBM message includes a URL for a website with openGraph tags, then a preview image may be displayed giving the impression of richer content.

Be aware that the RCS client may allow the user to disable link previews.

One-time passwords for user verification

You can use RBM to send one-time passwords (OTPs) for automatic user verification with the SMS Retriever API. To learn more about the SMS Retriever and related APIs, see the SMS Retriever documentation. For details about automatic user verification in apps that have registered with the SMS Retriever API, see this flow diagram.

During the verification process, the SMS Retriever API listens for an RBM message. This message must contain an OTP and a hash that identifies the app. After the hash is matched with the app, the OTP is extracted and forwarded to the app for automatic user verification.

Here's a sample RBM text message for user verification: Your code is <OTP> <app hash>.

For example, Your code is 123456 M8tue43FGT.

Tip: Remember to set a message expiration for OTPs and other time-sensitive messages.

Media and PDF files

When you send a message with an image, video, audio, or PDF file, your agent must provide a publicly accessible URL for the content or directly upload the file. For media files, you can also specify a thumbnail image that lets users preview the content before clicking on it. For audio files, the default audio widget is used as a placeholder.

Important: For user privacy and security, the RBM platform downloads and processes media and PDF files from the provided URLs before delivering them to the user. This prevents agent tracking by unique URLs. Therefore, don't submit a high volume of unique URLs. The RBM platform does not support this, whether the URLs point to the same or different files. Use the same URL for identical files.

The RBM platform caches files for 60 days, and the API returns a file ID that your agent can include in messages to users. After 60 days, RBM removes files from the cache.

When specifying files by URL, it's best practice to set contentMessage.forceRefresh to false. Setting contentMessage.forceRefresh to true forces RBM to fetch new content from the specified URL, even if the URL content is cached, which increases message delivery times for users.

See the best practices for file size recommendations and limits.

The following code sends an image. For formatting and value options, see AgentContentMessage.

Suggestions

Your agent sends suggestions (suggested replies and suggested actions) in suggestion chip lists (maximum of 11 suggestions) or in rich cards (maximum of four suggestions).

Each suggestion has a maximum of 25 characters.

Suggested replies

Suggested replies guide users through conversations by providing responses that your agent knows how to react to.

When a user taps a suggested reply, your agent receives an event that contains the reply's text and postback data. The payload has a maximum of 2048 characters.

Example

The following code sends text with two suggested replies. For formatting and value options, see SuggestedReply.

Suggested actions

Suggested actions guide users through conversations by leaveraging the built-in functionality of the their devices. Your agent can suggest that users dial a number, open a location on a map, share a location, open a URL, or create a calendar event.

For each suggested action, you can optionally provide a fallback URL (maximum 2048 characters). This URL will open in a new browser window if the user's device doesn't support the suggested action.

When a user taps a suggested action, your agent receives an event that contains the action's postback data.

For formatting and value options, see SuggestedAction.

Dial a number

The Dial action guides the user to dial a phone number specified by your agent. Phone numbers can only include digits (0-9), plus sign (+), asterisk (*), and number sign (#). The E.164 international format (for example, [phone]) is supported but not required. That is, both [phone] and 1011 are valid entries.

Open a URL

The Open URL action lets you guide users to a web page specified by your agent. By default, the web page opens in the user's browser. If a user has a default app configured for the web page, that app will open instead. In that case, the icon on the suggested action button will be the app's icon.

The Open URL action also supports integrated webviews; see Open URL with webview.

Example

The following code sends an open URL action. For formatting and value options, see OpenUrlAction.

Open a URL with webview

The Open URL with webview action loads the specified web page inside the messaging app with the rendering engine of your default browser. This allows the user to interact with the web page without leaving the RBM conversation. If the user's device doesn't support webviews, the web page opens in the user's browser instead. To enable webviews, see OpenURLApplication.

Webviews have three display modes. For formatting and value options, see WebviewViewMode.

• Full: The web page takes up the full screen
• Half: The web page takes up half of the screen
• Tall: The web page takes up three quarters of the screen

Example

The following code sends an Open URL with webview action. For formatting and value options, see OpenURLAction.

Compose messages

The Compose action opens the user's messaging app so they can send messages to a predefined phone number, such as a Customer Support number.

Beta: We're gradually rolling out the Compose action in Google Messages, so you may not have access to it right away. To get access before the full rollout, you can join the Messages Open Beta program.

There are three types of Compose actions. For visual examples, see Compose a text, audio, or video message.

• Compose a text message: Opens the messaging app with prefilled text for the user to send.
• Compose an audio message: Opens the messaging app and launches the microphone so the user can record audio.
• Compose a video message: Opens the messaging app and launches the camera so the user can record a video.

Example

The following code sends a compose action. For formatting and value options, see ComposeAction.

Suggestion chip list

Your agent sends suggestion chip lists with messages to guide users' subsequent actions. The chip list only displays when the associated message is at the bottom of the conversation. Any subsequent messages in the conversation (from either a user or your agent) overwrite the chip list.

The chips in the list are suggested replies and suggested actions.

Chip lists contain a maximum of 11 suggestion chips, and each chip label can have a maximum of 25 characters.

For formatting and value options, see AgentContentMessage.

Rich cards

When you need to send a chunk of related information, media, or suggestions, you should send a rich card. Rich cards allow your agent to send multiple units of information in a single message.

Rich cards can contain the following items:

• An image or video
• Title text
• Description text
• Suggested replies and suggested actions (maximum 4)

A rich card can contain all of the listed items, but a card must contain at least an image, video, or title to be valid. A rich card can contain a maximum of four suggested actions and suggested replies.

Your agent can send multiple rich cards together in a rich card carousel.

The maximum size of a rich card payload is 250 KB. See the best practices for media file size recommendations and limits.

You can find the rich card specifications in Rich cards.

Card height

Cards expand vertically to fit their contents. Rich cards have a minimum height of 112 DP and a maximum height of 344 DP. If the contents of a card are not large enough to fill the minimum card height, the card expands and fills the extra height with whitespace.

Media in rich cards must fit one of three heights:

• Short: 112 DP
• Medium: 168 DP
• Tall: 264 DP

If the media doesn't fit the dimensions within the card given the selected height, the media preview is chosen by zooming and cropping the media.

Example

The following code sends a rich card with an image and suggested replies. For formatting and value options, see RichCard.

Rich card carousels

When you need to present a user with multiple options to choose between, use a rich card carousel. Carousels string together multiple rich cards, allowing users to compare items and react to each individually.

Carousels may contain a minimum of two and a maximum of ten rich cards. Rich cards within carousels must conform to general rich card requirements for content and height. You can find the carousel specifications in Rich cards.

The maximum size of a rich card carousel payload is 250 KB. See the best practices for media file size recommendations and limits.

Truncation

Much like rich cards, many factors (such as screen resolution, pixel density, and user preferences) affect how cards appear to end users. In a carousel, however, the height of the first few cards defines the height of all the cards in the carousel, and card height affects title, description, and suggestion truncation.

If a device can't display all elements of a card because of display constraints or card height, RBM truncates the card until it can display on the device, using the following logic:

1. Reduce the description to one line.
2. Reduce the title to one line.
3. Omit suggestions that don't fit in the card, starting from the end of the defined list.
4. Omit the description.
5. Omit the title.

To avoid truncation, keep titles and descriptions as short as possible. For tall media, use either a title and description or one suggestion. For medium media, use up to two suggestions. For short media, use up to three suggestions. To fit four suggestions, don't include media in the card.

Keep cards roughly equivalent in terms of content sizing and length, and if necessary, front-load the carousel with larger cards to avoid truncation in following cards.

Example

The following code sends a rich card carousel. For formatting and value options, see RichCard.
