Facebook API Errors

Solution to the Missing Permission Error

December 12, 2021 by cryan.com

If your a developer using Facebook's API you may have encountered some of these errors:

  • Error validating access token: The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons.
  • Error Downloading Account: ('(#100) Missing permissions', 
  Response:
    {
      "error": {
        "message": "(#100) Missing permissions",
        "type": "OAuthException",
        "code": 100,
        "fbtrace_id": "AIxe3azfOU99dz1pMuLlN-A"
      }
    }

Easy Solution

The reason for these errors is that the user hasn't fully validated themself to Facebook. They have to prove to Facebook that they are a real person.

This is done by going to the users Facebook Settings page, https://www.facebook.com/settings/ and selecting the "Identiy Confirmation."

Facebook Identity

You'll Have to Wait!

Part of the process involves Facebook sending you a postcard to verify your address. Once you get the card, you enter the code and Facebook will enable all the Ad feeatures. This should eliminate the "Missing Permissions" error message.
