Overview

The View message API allows you to fetch data from a single push, email, or SMS message at a time. If you want to get multiple messages at a time, use the View messages API. In most cases, you will likely want to use Event Streams instead.

Currently this API does not provide Journey-sent messages. See Journey analytics for details.

Messages sent through the API are only accessible 30 days after creation; however, messages sent using the OneSignal dashboard are accessible for the app’s lifetime.

See our Rate limits for details on how often you can pull your message data with this API.

​
How to use this API

This API is most commonly used when sending Transactional messages to individual users. The response of our Create message API has an id which corresponds to the message_id used in this request. You can store this message_id on your server and (after giving your users some time to interact with the message) pull the data if desired.

For example, if you send a message targeting the include_aliases parameter, the response will include the aliases you set. If you send with the included_segments parameter, then the response will only provide the segments you set. When targeting segments or filters, you can use the Export audience activity CSV API to get the user event data.

To view outcome data for the message, you must include the outcome_name parameter with the name of the outcome you want to fetch, along with the accompanying aggregation type (.count or .sum), for example: os__click.count. For more information on outcome definitions, see View Outcomes.
