I get authorization codes without issue but when using the following code I only get the response below.
<html> <head><title>400 Bad Request</title></head> <body> <center><h1>400 Bad Request</h1></center> <hr><center>cloudflare</center> </body> </html>
The code I am using to call for the access token is below.
// Use cURL to get access token and refresh token
$ch = curl_init();
// Define base URL
$base = 'https://authz.constantcontact.com/oauth2/default/v1/token';
// Create full request URL
$url = $base . '?code=' . $_GET['code'] . '&redirect_uri=' . urlencode(DOMAIN.'connect/constantcontact/') . '&grant_type=authorization_code';
//echo $url;
curl_setopt($ch, CURLOPT_URL, $url);
// Set authorization header
// Make string of "API_KEY:SECRET"
$auth = $this->_clientID . ':' . $this->_clientSecret;
//echo $auth;
// Base64 encode it
$credentials = base64_encode($auth);
// Create and set the Authorization header to use the encoded credentials, and set the Content-Type header
$authorization = 'Authorization: Basic ' . $credentials;
curl_setopt($ch, CURLOPT_HTTPHEADER, array($authorization, 'Accept: application/json', 'Content-Type: application/x-www-form-urlencoded'));
// Set method and to expect response
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Make the call
$result = curl_exec($ch);
curl_close($ch);
print_r($result);
Any ideas on what could be causing this? We are following the docs exactly...
I solved this by adding the following to the post body
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode(['client_id' => $this->_clientID, 'client_secret' => $this->_clientSecret, 'code' => $_GET['code']]) );
