API, webhooks and Zapier

Your heyhey account connects to the outside world from Settings.

API keys

You can create API keys with limited permissions. Each key is shown only once, when you create it, and carries a prefix so you can easily recognise it in your code. The REST API covers the core objects in your account (contacts, products, orders and more), so your own scripts and integrations can read and write real data.

Webhooks

Outgoing webhooks fire on account events. There are eighteen of them, including new contacts, new orders and member sign-ups. Every webhook sends a signed payload, so the receiver can verify that it’s genuine. Deliveries are queued and retried, and the delivery log shows what fired and how the receiver responded.

Zapier

The API and webhooks are exactly the language Zapier speaks: trigger a Zap when a contact is created, or push a new row from a spreadsheet into your contacts. If you can describe an automation in one sentence, you can usually build it in a few minutes.

Claude and AI tools

Your account also connects to Claude as a set of tools through the Model Context Protocol (MCP). See Connecting Claude to your account.

A note on security: API keys and webhooks are limited to your own account. No key can read anyone else’s data.
