SendApp Webhook API endpoint

If you have the desktop software SendApp Connect, you can create a PHP file on your server with ssl certificate, to receive all messages from your clients in JSON format. Once you have set up your PHP file, you will simply have to enter the URL into your SendApp Connect. This way, all incoming messages from your WhatsApp account will be sent to your endpoint in json format.
