When someone messages your WhatsApp or Instagram, HookMyApp hands that message to your code, then sends your code’s reply right back to them. Your number and account stay yours, and nothing in the middle reads your messages. New here? Start with the quickstart for your channel, then connect your own number or account when you are ready.
