When something happens

Lemon Squeezy sends a webhook to your app, and the app asks AI what happens next.

  1. When

    Lemon Squeezy reports that a subscription payment failed.

    AI decides

    AI looks at the customer and the history and drafts a friendly message.

    Then

    You get the draft by email to approve.

A screen for your team or customers

An app on your own address, with sign-in, on top of the same Lemon Squeezy data.

  • For your customers

    Customers sign in and see their orders, license keys and next payment date.

Add Hypamoon

Text messages, email, phone, payments and agents run in the same project as the adapter.

  • Agent on a schedule

    An agent pauses a subscription when a customer asks, after you approve.

    AI proposes, you approve

Lemon Squeezy stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Lemon Squeezy waits for your approval, one call at a time. How adapters work

Good to know

  • Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
  • The API allows 300 calls per minute. Lemon Squeezy is a merchant of record, so it is the seller on the invoice.
