The Transactional API allows you to send action-oriented or time-sensitive push notifications to a specific user ID or to a group of IDs (device token, install ID or custom user ID).
Once your POST successfully reaches the API endpoint, you should receive an HTTP 201 confirmation and a unique Transactional response token representing the transaction.
You can display information related to the transactional push notifications delivery using the Transactional response token in the debug tool (Dashboard settings > Debug).
This allows you to check the effective sending time of a transactional push as well as the API call time to monitor potential latencies.
If the POST data does not meet the API requirements you will receive an actionable error message.
