Twitter 1.1 OAuth authenticity_token_error(99)

Question

I use the following code to get the bearer token:

$token = base64_encode($client_id.\':\'.$client_sec);

$data = array (\'grant_type\' => \'client_credent         


        

Answer 1

After fighting with this problem, i finally come up with the solution. Twitter is not actually sending the right message if error exist anywhere.

When i send request from curl, it works fine but when through code. i was having same error {"errors":[{"label":"authenticity_token_error","code":99,"message":"Unable to verify your credentials"}]}

So what i got, problem was lying with Access control header. setting these header does not work for me

     xhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded")
     xhttp.setRequestHeader('Access-Control-Allow-Headers', '*');
     xhttp.setRequestHeader('Access-Control-Allow-Origin', '*')
     xhttp.setRequestHeader('X-Requested-With', 'XMLHttpRequest')

as a workaround i just used this url to bypass request to handler cors

https://cors-anywhere.herokuapp.com/https://api.twitter.com/oauth2/token

added "https://cors-anywhere.herokuapp.com/" before the actual url and it began to work. hope someone may face this issue in problem
