Getting Authentication error while calling the Orange Number Verification service

Question

We are implementing the Orange Number Verification API. For this, we need to call an Orange service. This service has Bearer type authentication (Oauth2). I am able to get access token successfully and access token validity is 90 days. By using latest access token, I tried to call an Orange service by sending the access token in header but getting unauthorized access error every time.

```
curl -X POST 
-H "Authorization: Basic NktSSHljksdj7P...Jjndb6UdnlrT2lOaA==" 
-d "grant_type=authorization_code
&code=OFR-908cb0277a7e3d358c39d0792750875e...f4139a840cdcb6e
&redirect_uri=https%3F%2F%2Fwww.myserver.com"

```

Can you try to change quote ' to "? Like this:

```
$requestArray = [
    'name' => 'User',
    'age'  => 100
];

'header'  => "Content-type: application/x-www-form-urlencoded
" .
             "Authorization: Bearer xxxxxxxxxxxxxxxxx
",
'content' => http_build_query($requestArray)
Because 
 doesn't work inside one quote ', it sends 'as is'
```
