Laravel Socialite Facebook error: “POST https://graph.facebook.com/oauth/access_token resulted in a `400 Bad Request` ” [duplicate]

Answer 1

Yeah, I didn't check the request at all to see what's returned but someone on Larachat helped me solve this problem.

All I had to do before getting the user and handle the request was to add the following code in the callback method:

if (!$request->has('code') || $request->has('denied')) {
   return redirect('/');}

Answer 2

What's your Laravel version?

I've experienced the exact same problem and after going through the socialite package and make little changes, it solves the problem. You might want to give it a try.

vendor/laravel/socialite/TwoFacebookProvider line 81

Replace this

parse_str($response->getBody(), $data);

with

$data = json_decode($response->getBody(), true);

It seems like the data isn't adding

Answer 3

I had this message on my local machine after getting secret key value from .env file

ClientException in RequestException.php line 111:
enter code here Client error: `POST 
https://graph.facebook.com/v2.8/oauth/access_token` resulted in a `400 
Bad Request` response:
{"error":{"message":"Error validating client 
secret.","type":"OAuthException","code":1,"fbtrace_id":"ID"}}

As expected problem was with secret key, I pasted it wrong, so after double check and right copy/past from fb everything worked.

Hope this info will help somebody.
