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, a rich card, an image, or a video as well as suggested replies and suggested actions.
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 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 403 error.
If you send a message with features that a user's device doesn't support, the RBM platform returns an error and doesn't deliver your message.
The maximum size of the entire stringified AgentMessage is 250 KB. Rich cards and other media contribute to this size limit. The text portion of the message has its own limit of 3072 characters.
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 Revocation can prevent offline users from receiving an outdated message when they come back online.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.
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

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 UTF-8 characters.
Enter some text in the box to check its length:
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.
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.
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.
See the best practices for file size recommendations and limits.
File URL example
The following code sends an image. For formatting and value options, see

Suggested replies
Suggested replies guide users through conversations by providing responses that your agent knows how to react to. Your agent sends suggested replies in suggestion chip lists or in rich cards.
When a user taps a suggested reply, your agent receives an event that contains the reply's text and postback data.
Suggested replies have a maximum of 25 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. Your agent sends suggested actions in suggestion chip lists or in rich cards.
When a user taps a suggested action, your agent receives an event that contains the action's postback data.
Suggested actions have a maximum of 25 characters.
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,
+14155555555
) is supported but not required. That is, both +14155555555
and
1011
are valid entries.

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
- A list of 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 or suggested replies. It can't contain a combination of suggested actions and suggested replies on a single card.
Your agent can send multiple rich cards together in a rich card carousel.
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.
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:
- Reduce the description to one line.
- Reduce the title to one line.
- Omit suggestions that don't fit in the card, starting from the end of the defined list.
- Omit the description.
- 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,
