DeleteSubscribe. Unsubscribe a Contact from a Group.

You can unsubscribe contacts from a group in your JustClick account by requesting a query to the API service using software methods.

The query is sent by the POST method in the URLencode format to the address: http://username.justclick.io/api/DeleteSubscribe.

Where username is the login of the user in the system, as well as their domain of the third level in the JustClick service.

Parameters Transferred in the Query

• lead_email is the email of the unsubscribing contact
• rass_name is the unsubscribing client contacts group identifier

Both fields are required.

How Does It Work?

Your system will receive the result of the function in response. The response is coded in JSON format. For more details, see the “API Service Responses“.

The activation confirmation letter will not come after re-subscribing.

Example of Changing the Contact Data in PHP

In the example, we unsubscribe the user with the “[email protected]” email from the “super” group. Login to the system is “username”.

Function GetHash forms the hash to the transferred data.

Function CheckHash checks the hash of the service response.

 // Login to the JustClick system
 $user_rs['user_id'] = 'username';
 //The key for forming a hash. See API section (the link in the bottom right corner of the personal account).
 $user_rs['user_rps_key'] = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
 
 // Forming the data array for transferring to the API.
 $send_data = array(
   'lead_email' => '[email protected]', // user’s email 
   'rass_name' => 'super' // unsubscribing group

   );
// Forming the hash to the transmitted data.
$send_data['hash'] = GetHash($send_data, $user_rs);
// Forming the hash to the transmitted data.
$resp = json_decode(Send('http://username.justclick.io/api/DeleteSubscribe', $send_data));
//Checking the service response.
if(!CheckHash($resp, $user_rs)){
 echo "Error! The response hash is not valid!" ;
 exit;
}
if($resp->error_code == 0)
 echo "The user unsubscribed the group {$send_data['rid[0]']}. Service resonse: {$resp->error_code}";
else
 echo "Error code:{$resp->error_code} - description: {$resp->error_text}";
