Transform paypal curl get access token request into guzzle

Question

i'm needing some help with paypal rest api.

I'm using guzzle as http client to consume paypal api

When i try paypal example in command line with curl, it does works

but when i want reproduce it with guzzle i always get Internal 500 ERROR from paypal..

Here's paypal curl example from official docs ( check here https://developer.paypal.com/webapps/developer/docs/integration/direct/make-your-first-call/ ) :

curl -v https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "clientId:clientSecret" \
  -d "grant_type=client_credentials"

Here's my guzzle code :

/**
 * Etape 1 récuperer un access token
 */
$authResponse = $client->get("https://api.sandbox.paypal.com/v1/oauth2/token", [
    'auth' =>  [$apiClientId, $apiClientSecret, 'basic'],
    'body' => ['grant_type' => 'client_credentials'],
    'headers' => [
    'Accept-Language' => 'en_US',
    'Accept'     => 'application/json' 
    ]
]);

echo $authResponse->getBody();

I've tried with auth basic, digest but none worked so far.

Thanks for any help on this !

Answer 1

This is using guzzlehttp

$uri = 'https://api.sandbox.paypal.com/v1/oauth2/token';
$clientId = \\Your client_id which you got on sign up;
$secret = \\Your secret which you got on sign up;

$client = new \GuzzleHttp\Client();
$response = $client->request('POST', $uri, [
        'headers' =>
            [
                'Accept' => 'application/json',
                'Accept-Language' => 'en_US',
               'Content-Type' => 'application/x-www-form-urlencoded',
            ],
        'body' => 'grant_type=client_credentials',

        'auth' => [$clientId, $secret, 'basic']
    ]
);

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

$access_token = $data['access_token'];

Answer 2

Your issue is on the first line.

    $authResponse = $client->get

It should be a post.

     $authResponse = $client->post

I had a similar issue for a little bit.

EDIT: I also fond that if you want to use JSON for the body of a request either use json_encode or replace body with json, guzzle will handle the rest. In your previous code...

$authResponse = $client->post("https://api.sandbox.paypal.com/v1/oauth2/token", [
    'auth' =>  [$apiClientId, $apiClientSecret, 'basic'],
    'json' => ['grant_type' => 'client_credentials'],
    'headers' => [
        'Accept-Language' => 'en_US',
        'Accept' => 'application/json' 
    ]

]);
