Schedule API-triggered Canvases

post

/canvas/trigger/schedule/create

core endpoint

Use this endpoint to schedule Canvas messages (up to 90 days in advance) via API-triggered delivery, allowing you to decide what action should trigger the message to be sent.

You can pass in canvas_entry_properties that will be templated into the messages sent by the first steps of the Canvas.

Note that to send messages with this endpoint, you must have a Canvas ID, created when you build a Canvas.

See me in Postman

Rate limit

We apply the default Braze rate limit of 250,000 requests per hour to this endpoint, 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, each with individual message parameters
  • A segment of any size created in the Braze dashboard, specified by its segment_id
  • An ad-hoc audience segment of any size, defined in the request as a Connected Audience object

{
  "canvas_id": (required, string) see Canvas identifier,
  // Including 'recipients' will send only to the provided user ids if they are in the campaign's segment
  "recipients": (optional, array of recipients object),
  // for any keys that conflict between these trigger properties and those in a Recipients Object, the value from the
  // Recipients Object will be used
  "audience": (optional, connected audience object) see connected audience,
  // Including 'audience' will only send to users in the audience
  // If 'recipients' and 'audience' are not provided and broadcast is not set to 'false',
  // the message will send to entire segment targeted by the Canvas
  "broadcast": (optional, boolean) see broadcast -- defaults to false on 8/31/17, must be set to true if "recipients" object is omitted,
  "canvas_entry_properties": (optional, object) personalization key-value pairs for the first step for all users in this send; see trigger properties,
  "schedule": {
    "time": (required, datetime as ISO 8601 string) time to send the message (up to 90 days in the future),
    "in_local_time": (optional, bool),
    "at_optimal_time": (optional, bool),
  }
}

Request parameters

Parameter Required Data Type Description
canvas_id Required String See Canvas identifier.
recipients Optional Array of recipients objects See recipients object.
audience Optional Connected audience object See connected audience.
broadcast Optional Boolean You must set broadcast to true when sending a message to an entire segment that a campaign or Canvas targets. This parameter defaults to false (as of August 31, 2017).

If broadcast is set to true, a recipients list cannot be included. However, use caution when setting broadcast: true, as unintentionally setting this flag may cause you to send your message to a larger than expected audience.
canvas_entry_properties Optional Object Personalization key-value pairs for all users in this send. See Canvas entry properties object.
schedule Required Schedule object See schedule object.
