Why are my API-sent push notifications not appearing in Message History, even though the API call was successful?

When you send push notifications to fewer than 10 devices using our API, these are considered "transactional" messages. By default, transactional messages are not displayed in the Message History section of the control panel. This is done to optimize data storage and manage system load.

If you need to track these API-sent messages for testing or debugging purposes, you can use the API Message Tracing feature.

Here's how to enable it: 1. Navigate to Statistics → Message History in your control panel. 2. Click the Start API Message Tracing button, usually located in the upper right corner of the screen.

Once enabled, API Message Tracing will allow all messages sent via the API, including transactional ones, to appear in your Message History for one hour.

Important Notes: * API Message Tracing is enabled at the account level, not for a specific application. This means you can activate it from the Message History section of any app within your account, and it will apply globally. * If you are viewing the Message History for an application that has not had any messages sent to it yet, the Message History section might display a prompt to send your first message instead of an empty list. Activating API Message Tracing from another app (or after sending a test message through the UI to this app) will still allow you to trace API messages for this app.

For more details, you can refer to the API Message Tracing documentation.
