Failed to obtain access token

[suederade]

We are using WP Oauth Server and Passport-Oauth2-Complete-for-Wordpress and we are constantly running into this issue no matter what settings are chosen on WP Oauth Server. It is returned as code?=token, but never finds it.

InternalOAuthError: failed to obtain access token

Hi,
we have a similar issue, trying to authenticate using the wordpress credentials, but always getting a error back:
failed to obtain access token (status: 400 data: {"error":"invalid_request","error_description":"Unknown request"})
This is the kind of query string that is returned:
?code=xhgcfxpf5cmphkc8uoequhvvqhjjg0ybmtbaky&state=_

Could you get yours to work? And what was for you the solution?
Thanks for help
regards

Change
$response = $client->getAccessToken(TOKEN_ENDPOINT, 'authorization_code', $params);
to
$response = $client->getAccessToken(TOKEN_ENDPOINT, 'AuthorizationCode', $params);

Hi,

I'm getting the same error using WP Oauth Server and Passport-Oauth2-Complete-for-Wordpress

failed to obtain access token (status: 400 data: {"error":"invalid_request","error_description":"Unknown request"})

Where do I have to change the code in the Wordpress plugin or at the node passport-wordpress code?

Change
$response = $client->getAccessToken(TOKEN_ENDPOINT, 'authorization_code', $params);
to
$response = $client->getAccessToken(TOKEN_ENDPOINT, 'AuthorizationCode', $params);

Thanks!

I finally made it!

Using this module https://github.com/ido-ran/passport-wordpress-oauth-server

I think that complete-wordpress plugin uses an old version of oauth and that is why is not working...

Thanks!
