Identifying the Symptom: Invalid API Endpoint

When working with Mailgun, one common issue developers encounter is the 'Invalid API endpoint' error. This error typically manifests when an API request fails to reach the correct server endpoint, resulting in a failed operation.

Exploring the Issue: What Causes Invalid API Endpoint?

The 'Invalid API endpoint' error occurs when the URL specified in the API request does not match the expected endpoint format.

Step 1: Verify the API Endpoint URL

Ensure that the API endpoint URL in your request matches the format specified in the Mailgun API documentation. Check for any typographical errors and confirm that the domain and path are correct.

Step 2: Update to the Latest Endpoint

If you are using an outdated endpoint, refer to the Mailgun Base URL documentation to update your API requests to the latest endpoints. This ensures compatibility with the current API version.

Step 3: Test the Endpoint

Use tools like Postman or cURL to test the API endpoint. Send a sample request to verify that the endpoint is reachable and responds correctly.
