OneSignal is a leading Push Communication API provider that enables developers to send notifications across various platforms, including mobile and web applications. It is designed to enhance user engagement by delivering timely and relevant messages directly to users' devices.
When working with OneSignal, you might encounter an error indicating that required fields are missing from your API request. This typically manifests as an error message in your application logs or console output, preventing the successful delivery of push notifications.
The error message usually states: "Missing Required Fields". This indicates that your API request lacks essential information needed for processing.
The "Missing Required Fields" error occurs when the API request does not include all the necessary parameters. OneSignal requires specific fields to identify the target audience, message content, and other critical details for notification delivery.

Ensure your JSON payload is correctly structured. Use tools like JSONLint to validate your JSON format and catch any syntax errors.
