Adding a User to Active Campaign on WordPress New User Signup

This is one of those scenarios where I couldn't find the sample code for what I needed - and no one has yet to build a good plugin for this functionality. Not even Active Campaign!!

So, if you need to send a subscriber to your Active Campaign account when they sign up as a new user on your WordPress site, then this article has you covered. This is actually more for me so I can reference this in the future again when I need it!

The code below will go directly into your functions.php file inside of your WP theme. You'll have the option of adding users to a specific list as well.

You'll need to get your API URL and API Key from your Active Campaign account.

function add_user_to_active( $user_id ){ $user_info = get_userdata($user_id); $user_roles = $user_info->roles; // If this is a subscriber, then let's do this! if ( in_array( 'subscriber', $user_roles, true ) ) { $first_name = $user_info->first_name; $last_name = $user_info->last_name; $user_email = $user_info->user_email; $url = ''; $params = array( 'api_key' => 'YOUR_LONG_API_KEY', 'api_action' => 'contact_add', 'api_output' => 'serialize', ); // here we define the data we are posting in order to perform an update $post = array( 'email' => $user_email, 'first_name' => $first_name, // Optional if you don't collect this in your signup form 'last_name' => $last_name, // Optional if you don't collect this in your signup form 'p[3]' => 3, // example list ID (REPLACE '3' WITH ACTUAL LIST ID, IE: p[5] = 5) 'status[3]' => 1, // 1: active, 2: unsubscribed (REPLACE '3' WITH ACTUAL LIST ID, IE: status[5] = 1) 'instantresponders[3]' => 0, // set to 0 to if you don't want to sent instant autoresponders ); // This section takes the input fields and converts them to the proper format $query = ""; foreach( $params as $key => $value ) $query .= urlencode($key) . '=' . urlencode($value) . '&'; $query = rtrim($query, '& '); // This section takes the input data and converts it to the proper format $data = ""; foreach( $post as $key => $value ) $data .= urlencode($key) . '=' . urlencode($value) . '&'; $data = rtrim($data, '& '); // clean up the url $url = rtrim($url, '/ '); // This sample code uses the CURL library for php to establish a connection, // submit your request, and show (print out) the response. if ( !function_exists('curl_init') ) die('CURL not supported. (introduced in PHP 4.0.2)'); // If JSON is used, check if json_decode is present (PHP 5.2.0+) if ( $params['api_output'] == 'json' && !function_exists('json_decode') ) { die('JSON not supported. (introduced in PHP 5.2.0)'); } // define a final API request - GET $api = $url . '/admin/api.php?' . $query; $request = curl_init($api); // initiate curl object curl_setopt($request, CURLOPT_HEADER, 0); // set to 0 to eliminate header info from response curl_setopt($request, CURLOPT_RETURNTRANSFER, 1); // Returns response data instead of TRUE(1) curl_setopt($request, CURLOPT_POSTFIELDS, $data); // use HTTP POST to send form data //curl_setopt($request, CURLOPT_SSL_VERIFYPEER, FALSE); // uncomment if you get no gateway response and are using HTTPS curl_setopt($request, CURLOPT_FOLLOWLOCATION, true); $response = (string)curl_exec($request); // execute curl post and store results in $response // additional options may be required depending upon your server configuration // you can find documentation on curl options at curl_close($request); // close curl object if ( !$response ) { die('Nothing was returned. Do you have a connection to Email Marketing server?'); } } // END if is a subscriber } // This function is triggered whenever a new user // signs up for an account on your WordPress website add_action('user_register', 'add_user_to_active', 10, 1);

So there you have it! Everytime a user is added to WordPress (as a subscriber) they will be added to a specific list in your Active Campaign account.

Side note - there is a plugin that claims to do this but in my testing it didn't work at all.
