I am implementing PayPal Checkout (https://developer.paypal.com/docs/checkout/standard/integrate/) in a Symfony 5.4 project.
I am kind of stuck retrieving an access token by sending clientId and clientSecret to the PayPal REST API (https://developer.paypal.com/api/rest/authentication/) using Symfony HttpClient.
PayPal defines a curl request to get the token:
curl -v -X POST "https://api-m.sandbox.paypal.com/v1/oauth2/token" \
-u "<CLIENT_ID>:<CLIENT_SECRET>" \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "grant_type=client_credentials"
I was trying to do that using HttpClient from Symfony. Without any success unfortunately as I can't figure out how to pass the options.
I tried passing the options with extra.curl using CURLOPT_VERBOSE, CURLOPT_USERNAME, CURLOPT_HEADER (couldn't find a define for the grant_type option). It seems that setting header and verbose mode is not allowed in extra.curl so I tried setting that in the 'body' part instead. That led to 401 then.
Here is what I tried:
$response = $this->httpClient->request('POST', 'https://api-m.sandbox.paypal.com/v1/oauth2/token', [
'extra' => [
'curl'=> [
CURLOPT_VERBOSE => 1,
CURLOPT_USERNAME => $clientId.':'.$clientSecret,
CURLOPT_HEADER => "Content-Type: application/x-www-form-urlencoded"
]
]
]);
And alternatively:
$response = $this->httpClient->request('POST', 'https://api-m.sandbox.paypal.com/v1/oauth2/token', [
'body' => [
'Content-Type' => 'application/x-www-form-urlencoded',
'grant_type' => 'client_credentials'
],
'extra' => [
'curl'=> [
CURLOPT_USERNAME => $clientId.':'.$clientSecret,
]
]
]);
I couldn't find any proper HttpClient curl usage examples. So basicaly I am trying to understand how to realize the PayPal Auth request using HttpClient. Any hints on that would be most welcome.
CodePudding user response:
$response = $this->httpClient->request('POST', 'https://api-m.sandbox.paypal.com/v1/oauth2/token', [
'auth_basic' => [$clientId, $clientSecret],
// ...
]);
