Solution 1

I believed you have used different redirect_uri in your facebook app settings and Oauth API code. thats why you got this error.

For facebook login you must set same redirect_uri into both place.

Solution 2

You can set redirect URI in Go to https://developers.facebook.com/apps Select your app.

Under Products > Facebook Login > Settings

Enable Embedded Browser OAuth Login
Set Valid OAuth Redirect URIs

You can Validate Redirect URI with Redirect URI Validator.

You can only use https URIs. Also set App Domain in Settings > Basic > App Domains

Try / at the end of redirect URI

In my case I was using https://localhost everywhere but somehow when getting access token specifying https://localhost/ worked.

Solution 3

As absurd as it sounds, verify you're using the correct app_secret.

Facebook will give you this instead of just saying "invalid secret" in the response

So I'm out of ideas, I don't know what to check or debug anymore, but on the exception I get this:

string(188203) "Facebook\FacebookAuthorizationException Object
(
    [statusCode:Facebook\FacebookRequestException:private] => 400
    [rawResponse:Facebook\FacebookRequestException:private] => {"error":{"message":"Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request","type":"OAuthException","code":100,"fbtrace_id":"DqCCKoiN0r4"}}
    [responseData:Facebook\FacebookRequestException:private] => Array
        (
            [error] => Array
                (
                    [message] => Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request
                    [type] => OAuthException
                    [code] => 100
                    [fbtrace_id] => DqCCKoiN0r4
                )

        )

    [message:protected] => Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request
    [string:Exception:private] => 
    [code:protected] => 100

@Uffo In Basic or Advanced settings, you can see callback URL option.

@Uffo Do you have 'https' in your redirect_uri ? If yes then change it to 'http' in both place.

Adding the slash on the end fixed this for me (no slash was needed on the initial request)

Can indeed confirm this is the case, I missed one character when copy/pasting the secret resulting into this error. Thanks for saving me some time!

strangely enough, it accepts redirect_uri without trailing / for oauth request, but requires / when getting token
