This requires a base64-encoded string of your credentials in the format 'username:password'. - **Username**: Use your MoEngage workspace ID (also known as the App ID). You can find it in the MoEngage dashboard at **Settings** > **Account** > **APIs** > **Workspace ID (earlier app id)**. - **Password**: Use your API Key, which you can find within the **Data** tile. **Note**: After you generate and save the Data API Key, DO NOT generate a new key unless there is a security breach. After you generate a different Data API key and save it, the authentication will start failing. You must update your existing data tracking.
