Send messages immediately using the API only

post

/messages/send

core endpoint

Use this endpoint to send immediate messages to designated users using the Braze API.

If you are targeting a segment, a record of your request will be stored in the Developer Console.

See me in Postman

Prerequisites

To use this endpoint, you’ll need to generate an API key with the messages.send permission.

Rate limit

When specifying a segment or Connected Audience in your request, we apply a rate limit of 250 requests per minute to this endpoint. Otherwise, if specifying an external_id, this endpoint has a default rate limit of 250,000 requests per hour shared between /messages/send, /campaigns/trigger/send, and /canvas/trigger/send, as documented in API rate limits.

Braze endpoints support batching API requests. A single request to the messaging endpoints can reach any of the following:

  • Up to 50 specific external_ids
  • A segment of any size created in the Braze dashboard, specified by its segment_id
  • An audience segment of any size, defined in the request as a connected audience object

Response details

Message sending endpoint responses will include the message’s dispatch_id for reference back to the dispatch of the message. The dispatch_id is the ID of the message dispatch, meaning the unique ID for each “transmission” sent from Braze. For more information, refer to Dispatch ID behavior.
