Braze’s Send Identifier adds the ability to send messages and track message performance entirely programmatically, without campaign creation for each send. Using the Send Identifier to track and send messages is useful if you are planning to programmatically generate and send content.
The daily maximum number of custom send identifiers that can be created via this endpoint is 100 for a given app group. Each
campaign_id combination that you create will count towards your daily limit. The response headers for any valid request include the current rate limit status, see API rate limits for details.
