[nuruzzamanhimel0]

Hi, I am working with ebay API's. i have connectd Sandbox account and its working fine. But when i want to connect PRODUCTION then it give me error (request is missing a required parameter or malformed). i don't understand where is the problem. My code is here

public function getUserAccessToken($consent_token) {

$client = new Client();

$response = $client->request('POST', "https://api.ebay.com/identity/v1/oauth2/token",

[ 'headers' => [

'content-type' => 'application/x-www-form-urlencoded',

'Authorization' => $this->getBasicAuthorizationHeader()

],

'form_params' => [

'grant_type' => 'authorization_code',

'code' => $consent_token,

'redirect_uri' => xxx.....

]

]);

if ($response) {

$data = json_decode($response->getBody()->getContents());

return $data;

}

}

In moving from Sandbox to Production, have you remembered to change:

• client id
• client secret
• redirect_uri

Yes, I changed it but didn't work.
