Create scheduled messages

post

/messages/schedule/create

core endpoint

Use this endpoint to send messages directly from the API.

The create schedule endpoint allows you to schedule a campaign, Canvas, or other message to be sent at a designated time (up to 90 days in the future) and provides you with an identifier to reference that message for updates. If you are targeting a segment, a record of your request will be stored in the Developer Console after all scheduled messages have been sent.

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

Request parameters

Parameter Required Data Type Description
broadcast Optional Boolean See broadcast. This parameter defaults to false (as of August 31, 2017).

If recipients is omitted, broadcast must be set to true. 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.

user_aliases Optional Array of user alias objects See user alias object.
audience Optional Connected audience object See connected audience.
segment_id Optional String See segment identifier.

recipient_subscription_state Optional String Use this to send messages to only users who have opted in (opted_in), only users who have subscribed or are opted in (subscribed) or to all users, including unsubscribed users (all).

Using all users is useful for transactional email messaging. Defaults to subscribed.
schedule Required Schedule object See schedule object
