Understanding OneSignal: A Powerful Push Communication API

OneSignal is a leading Push Communication API provider that enables developers to send notifications across various platforms, including web, mobile, and email. It is widely used for its ease of integration and robust features that enhance user engagement and retention.

Identifying the Symptom: Invalid Language Code Error

When using OneSignal, you might encounter an 'Invalid Language Code' error. This typically occurs when attempting to send notifications with a language code that OneSignal does not recognize or support.

Exploring the Issue: What Causes the Invalid Language Code?

The 'Invalid Language Code' error arises when the language code specified in your API request does not match any of the supported language codes by OneSignal. This can happen due to typos, outdated codes, or unsupported languages.

Common Scenarios Leading to the Error

  • Using a language code that is not part of the OneSignal supported languages.
  • Incorrectly formatted language codes.
  • Attempting to use a regional dialect that is not supported.

Steps to Fix the Invalid Language Code Issue

Resolving this issue involves ensuring that the language code used in your API requests is valid and supported by OneSignal.

Step 1: Verify Supported Language Codes

First, check the list of supported language codes in the OneSignal documentation. Ensure that the code you are using is included in this list.

Step 2: Correct the Language Code in Your Request

Once you have verified the correct language code, update your API request to use this code. For example, if you were using 'en-UK' and the supported code is 'en-GB', make the necessary change.

{
"app_id": "YOUR_APP_ID",
"contents": {"en": "Your message here"},
"included_segments": ["All"],
"language": "en-GB"
}

Step 3: Test Your Notification

After making the changes, test your notification to ensure it is sent without errors. Use OneSignal's notification creation guide for reference.

Conclusion

By following these steps, you can effectively resolve the 'Invalid Language Code' error in OneSignal. Always ensure to keep your language codes updated and refer to the official documentation for any changes or updates in supported languages.
