Developers

Build perks natively into your product.

A partner-authenticated REST API, a drop-in embed widget, and signed webhooks, with an isolated sandbox so you can integrate without touching live members.

Authentication

Each partner is issued a public and private key. Exchange them at the authentication endpoint for a short-lived token, then send that token as a bearer credential on subsequent requests. Start with sandbox keys to build safely, then switch to live keys when you’re ready.

What you can build

  • Read the catalogue: categories and deals behind your own front-end.
  • Sync & read members scoped to your partner account.
  • Embed the widget: a config-driven iframe themed via URL parameters.
  • Subscribe to webhooks: signed payloads, delivery logs and a test send.
  • Test in the sandbox: an isolated twin with seeded deals and test keys.

Webhooks

Register an endpoint, copy the signing secret, and verify each delivery’s signature before trusting it. Inspect every attempt in the delivery log and replay a test event to confirm your handler.
