Dispatch ID Behavior
dispatch_id is the ID of the message dispatch - a unique ID for each “transmission” sent from Braze. Users who are send a scheduled message get the same
dispatch_id, while action-based or API-triggered messages will receive a unique
dispatch_id per user.
These IDs are per user, per Campaign for triggered (action-based or API-triggered) messages. This can result in two different users having different
dispatch_ids for a single Campaign if messages were sent at two different times. This is often because the API requests were made separately. If both users were in the same campaign audience in a single send, their Dispatch IDs would be the same.
Dispatch ID Behavior in Campaigns
Scheduled Campaign messages get the same
dispatch_id. Action-based or API-triggered Campaign messages will get a unique
dispatch_id per user.
Multi-channel Campaigns will have the same behavior as described above.
For example, if Becky and Tom are both included in your scheduled Campaign audience, then they will have the same
If they are included in the audience of an API-triggered Campaign, they will have different
Dispatch IDs are generated randomly for all Canvas Steps because Braze treats Canvas Steps as triggered events, even when they are “scheduled”. This may result in inconsistencies generating the ids. Sometimes, a Canvas step will have unique
dispatch_ids per user per send, or it may have shared
dispatch_ids across users per send.

Template Dispatch ID into Messages with Liquid
If you want to track the dispatch of a message from within the message (in a URL, for example), you can template in the
dispatch_id. You can find the formatting for this in our list of Supported Personalization Tags, under Canvas Attributes.
This behaves just like
api_id, in that since the
api_id isn’t available at Campaign creation, it is templated in as a placeholder and will preview as
dispatch_id_for_unsent_campaign. The id is generated before the message is sent, and will be included in as send time.
Liquid templating of
dispatch_id_for_unsent_campaign does not work with in-app messages, since in-app messages don’t have a
Dispatch ID Currents Field for Email
In the effort to continue enhancing our Currents capabilities, we’re adding
dispatch_id as a field to Currents Email events across all connector types.
dispatch_id is the unique id generated for each transmission – or, dispatch – sent from the Braze platform.
While all customers who are sent a scheduled message get the same
dispatch_id, customers who receive either action-based or API triggered messages will get a unique
dispatch_id per message. The
dispatch_id field enables you to identify which instance of a recurring campaign is responsible for conversion, thus equipping you with more insights and information on which types of campaigns are helping push the needle on your business goals.
