I just manually implemented a facebook oauth2 flow into my webapp. After receiving the correct access_token and trying to call the graph api for user data I got a 400 BAD REQUEST as response.
GET https://graph.facebook.com/me?accessToken=MY_CORRECT_TOKEN&fields=id,name,email
When I use exactly the same call within the dev tools provided on facebook it succeeds, but when I try using any other http client it doesnt work. I already tried it with curl, apache commons and some other http clients.
Is there someone able to help me with this?
Thanks in advance

An access token is an opaque string that identifies a user, app, or Page and can be used by the app to make graph API calls. When someone connects with an app using Facebook Login and approves the request for permissions, the app obtains an access token that provides temporary, secure access to Facebook APIs.
Applies to all versions. Facebook Analytics will no longer be available after June 30, 2021. Additionally, we are deprecating the App Dashboard Plugin for Marketing API. For more information visit the Business Help Center.
OAuthException: If you receive an OAuthException error, it means that Edgar doesn't have the correct permissions to access your Facebook accounts right now. The password may have been changed on Facebook or Facebook may have reset your security session.
The format of your API call is incorrect. Try the following instead:
GET https://graph.facebook.com/me?access_token=MY_CORRECT_TOKEN&fields=id,name,email
The accessToken in your URL should actually be access_token.

For people landing here with the same error message but different problem, you can also check, if you have both IPv4 and IPv6 connections, that both IPs (v4 and v6) are authorized in Facebook OAuth parameters (on developer.facebook.com). That solved my problem.
