Send additional form data when requesting access_token with OAuth2

[77media-creations]

Hi there,

Great package first of all. I have recently started to implement in my laravel package.

In this particular project, I'm trying to integrate external APIs (Machine to Machine) with OAuth2 authentication.

This service requires username: xxx and password: xxx along with client_id: xxx and 'client_secret: xxx**passed in the request body** when requesting anaccess_token`.

I'm not sure where to pass these additional variables within the connector class.

So far, I have done the following:

class ServiceConnector extends Connector
{
    use ClientCredentialsGrant;

    public function __construct(public array $connectionData)
    {
    }

    /**
     * The Base URL of the API.
     */
    public function resolveBaseUrl(): string
    {
        return $this->connectionData['base_url'];
    }

    /**
     * The OAuth2 configuration
     */
    protected function defaultOauthConfig(): OAuthConfig
    {
        return OAuthConfig::make()
            ->setClientId($this->connectionData['client_id'])
            ->setClientSecret($this->connectionData['client_secret'])
            ->setRedirectUri($this->connectionData['base_url'])
            ->setDefaultScopes($this->connectionData['scopes'])
            ->setTokenEndpoint($this->connectionData['token_url'])
            ->setRequestModifier(function (Request $request) {
                if ($request instanceof GetClientCredentialsTokenRequest) {
                    $request->body()->set([
                        'username' => $this->connectionData['username'],
                        'password' => $this->connectionData['password'],
                        'grant_type' => 'password',
                    ]);
                }
            });
    }

}

It seems like the variables passed via the setRequestModifier() method are not correctly going with the request as form body.

Am I missing something somewhere or this type of authentication has a different approach?

Any help is appreciated.

@77media-creations In case you are still stuck on this the solution for me was to modify the code like this:

  ->setRequestModifier(function (Request $request) {
      if ($request instanceof GetClientCredentialsTokenRequest) {
          $request->body()->set([
                                    'username' => $this->connectionData['username'],
                                    'password' => $this->connectionData['password'],
                                    'client_id' => $this->connectionData['clientId'],
                                    'client_secret' => $this->connectionData['client_secret'],
                                    'grant_type' => 'password',
                                ]);
      }
  });

The client_id and client_secret needed to be added and everything worked from there.
