Sending Campaign Messages via API-Triggered Delivery

post

/campaigns/trigger/send

API-triggered delivery allows you to house message content inside of the Braze dashboard while dictating when a message is sent, and to whom via your API.

The send endpoint allows you to send immediate, ad-hoc messages to designated users. If you are targeting a segment, a record of your request will be stored in the Developer Console. Please note that to send messages with this endpoint, you must have a Campaign ID created when you build an API-triggered campaign.

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 (unique id for each ‘transmission’ sent from the Braze platform). For more information on dispatch_id checkout out our documentation.

Create Send Endpoint

Using the Attributes Object in Campaigns

Braze has a Messaging Object called Attributes that will allow you to add, create, or update attributes and values for a user before you send them an API-triggered campaigns using the campaign/trigger/send endpoint as this API call will process the User Attributes object before it processes and sends the campaign. This helps minimize the risk of there being issues caused by race conditions.
