# Passtastic API

> Passtastic is a digital loyalty platform (Apple Wallet / Google Wallet cards) for
> small and medium businesses. The public REST API lets you enroll customers, award
> and redeem stamps/points, read balances, and subscribe to webhooks from your own
> POS, CRM, or app — Passtastic keeps the customer's wallet pass in sync automatically.
> Auth is a static `X-Api-Key` header; get a key from the Passtastic dashboard under
> Settings → API & Webhooks. This file is a short index — for the full reference
> (every endpoint, request/response examples, webhook signature verification code,
> and integration recipes) in one self-contained document, fetch `/llms-full.txt`.

## Docs

- [Full API reference](https://passtastic.io/llms-full.txt): every `/v1` endpoint
  (customers, earn/redeem/adjust, webhooks), request/response examples, the webhook
  event catalog, HMAC signature verification (JS + Python), and integration recipes —
  in one markdown file, meant for an AI agent to ingest in a single fetch.
- [Human-readable developer docs](https://passtastic.io/developers): the same
  reference rendered as a browsable page, including quickstart and "Build with AI".

## Get a key

- [Settings → API & Webhooks](https://passtastic.io/account?tab=developer): create or
