Hello,
Thank you for reaching out to Constant Contact API Developer Support.
There are a few reasons that you may get a 401 error response, and more detail should be included in the error response message. In order to troubleshoot this further, I'd recommend capturing any error messages. For example:
public function register_contact($email, $first_name, $country, $zip)
{
// Initialize a cURL object
$payload = json_encode(array(
"email_address" => array("address" => $email, "permission_to_send" => "implicit"),
"first_name" => $first_name,
"create_source" => "Account"
));
// Define base URL
$base = 'https://api.cc.email/v3/contacts';
// Create full request URL with chosen parameters
$url = $base;
// Set the URL
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, true);
// Add option to capture the error response
curl_setopt($ch, CURLOPT_FAILONERROR, true);
// Set authorization header
$authorization = 'Authorization: Bearer ' . get_option('constant_token');
curl_setopt($ch, CURLOPT_HTTPHEADER, array($authorization));
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
// Make the call
$result = curl_exec($ch);
// Check for error
if (curl_errno($ch)) {
$error = curl_error($ch);
}
// Close cURL
curl_close($ch);
// Display results
if (isset($error)) {
echo $error;
} else {
echo $result;
}
}
Please have a look and let me know what the error response message you are seeing is, so that we can look into this in more detail.
