Requirements

The following versions of PHP are supported.

• PHP 5.6
• PHP 7.0
• PHP 7.1
• PHP 7.2

API Key

All API calls require an API Key. You can find your API Key in the ConvertKit Account page.

API Secret

Some API calls require an API Secret. All calls that require the api key will also work with the api secret, there's no need to use both. This key grants access to sensitive data and actions on your subscribers.

Usage

Start by using ConvertKit API and creating an instance with your ConvertKit API key

$api = new \Firewards\Apis\ConvertKit($api_key, $api_secret);

    {
        break;
    }
    
    var_dump($subscribers);
