Facebook login ant not fetch email

A common issue!

When using Facebook Login, you may encounter situations where the email address is not fetched or is not available. Here are some possible reasons and solutions:

  1. Facebook Login settings: Ensure that you have enabled the "Email" permission in your Facebook Login settings. You can do this by going to your Facebook Developer account, selecting your app, and clicking on "Settings" > "Basic" > "Facebook Login". Make sure the "Email" permission is enabled.
  2. User's Facebook settings: Check if the user has enabled the "Email" permission for your app in their Facebook settings. Users can do this by going to their Facebook account settings, clicking on "Apps and Websites", and selecting your app. If the "Email" permission is not enabled, the user will need to do so.
  3. Facebook Login version: Ensure that you are using the latest version of the Facebook Login SDK. Outdated versions may not fetch email addresses correctly.
  4. Error handling: Check your error handling code to see if there are any errors occurring during the login process. You can use the Facebook Login SDK's error handling mechanisms to catch and handle any errors that may occur.
  5. Facebook's email policy: Facebook has strict policies regarding email addresses. If a user has not provided an email address or has opted out of sharing their email address, it may not be available for your app to fetch.
  6. User's Facebook account type: If the user has a Facebook account that is not associated with an email address (e.g., a Facebook account created using a phone number), the email address may not be available for your app to fetch.
  7. Facebook's rate limiting: Facebook has rate limits on the number of requests you can make to their API. If you are making too many requests, you may encounter errors or limitations on the data that is returned, including email addresses.

To troubleshoot the issue, you can try the following:

  1. Check the Facebook Login SDK's documentation and error handling mechanisms to see if there are any specific solutions or workarounds for this issue.
  2. Use the Facebook Login SDK's debug logging feature to see if there are any errors or warnings occurring during the login process.
  3. Test the login process with different users to see if the issue is specific to a particular user or account type.
  4. Reach out to Facebook's support team for assistance with resolving the issue.
