Fixing “Missing X-Auth-Key on Cloudflare API” Issue

When we face the Error: Unknown X-Auth-Key or X-Auth-Email (err code: 9103), we can try the following steps in order to fix the issue efficiently:

1. Make sure we’ve got a Global API key or made an API token with the right permissions for the desired action.

2. When making API requests, we must provide the X-Auth-Key header in the request. The format is usually as follows:

Authorization: Bearer YOUR_API_TOKEN, we must change “YOUR_API_TOKEN” with the actual API token or Global API key.

3. Make sure we’re using the correct API key or token in the request headers.

4. Check the API request’s header names and values to ensure they are properly formatted.

5. If the given key or token is incorrect, recreate it using the Cloudflare dashboard and update the app or script with the new details.

6. If we’re using an API token, ensure sure it has the needed rights for carrying out the tasks we’re trying to carry out via the API.

7. Use the correct key type (API token or Global API key, depending on the method).

8. Check that the token we’re using has the necessary rights for the specified activity (for example, “Zone:DNS:Edit” for Let’s Encrypt).

9. Check that the API request includes the correct header: “Authorization”.

10. The header value should be formatted as “Bearer YOUR_API_TOKEN” (replace with the real token).

11. Unless absolutely needed, we must avoid using the Global API key in code or scripts owing to security concerns.
