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.

This endpoint allows you to send Campaign messages via API Triggered delivery, allowing you to decide what action should trigger the message to be sent. 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 attribute 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.

Click to read about the Benefits of using the Attributes Object with this Endpoint

When user information is sent to Braze via the users/track endpoint, it may occasionally take a few seconds for the user to be created in Braze’s system or for the data to propagate to the user’s profile.

When requests are made to the users/track and messaging endpoints at around the same time, Braze cannot guarantee that the request to the users/track endpoint will be processed before the request to the messaging endpoint. This can result in race conditions that can impact messaging: for example, a user may not yet have been created in Braze’s system when a request to the campaigns/trigger/send endpoint is processed, resulting in the user not receiving an API-triggered push campaign.

This is especially useful when you want to guarantee that a user has been created or that new data has populated to a user’s profile before a message is sent to a user.

  • For example, you might want to send an order confirmation to a customer that just registered. Because the user’s email information is not yet in Braze, you’ll want to make sure that Braze processes the user’s email address before the order confirmation campaign is sent to them.
  • Another example is ensuring that user attributes needed for campaign segmentation are processed before the campaign is sent. You might have a segment on your API triggered campaign that references an attribute value like gender, which is provided by the user during the registration process. If the attribute isn’t updated on the user’s profile before the campaign segmentation is evaluated, the user will not get the campaign.

Use the Attributes Object in this endpoint to guarantee that:

  • Users are created before a request to the campaign/trigger/send endpoint is processed.
  • User attributes are updated before a request to the campaign/trigger/send endpoint is processed.

Attributes that are included in this object will be processed before Braze begins to send the campaign. If the send_to_existing_only flag is set to false, and an external_user_id does not exist in Braze’s database, Braze will create a user profile for the external_user_id and process the associated attributes to the user profile before Braze begins to send the campaign. Also note, if the send_to_existing_only flag is set to false, then the attributes object must be included in order to create the user.
