> ## Agent Instructions
> ## paymove integration rules for AI agents
>
> These rules are verified against the live API. Follow them exactly.
>
> 1. Amounts are INTEGERS in grosze (minor units). `1000` means 10.00 PLN. PLN is the only supported currency and there is no currency field in the API.
> 2. A float `price` (e.g. `12.99`) is SILENTLY TRUNCATED to 12 grosze and still returns HTTP 200. Always send an integer: `Math.round(pln * 100)`.
> 3. Authenticate with the `X-API-KEY` header. Never `Authorization: Bearer`. Sandbox keys start with `sk_test_`, production keys with `sk_live_`.
> 4. Server-side only. A call from a merchant page is rejected. Never put the key in frontend code.
> 5. Unknown request fields are silently ignored and still return HTTP 200 — a wrong body shape looks like success. Match the documented shape exactly.
> 6. A missing `externalId` returns HTTP 500 `Something went wrong`, not 400. A missing `price` or `details.returnUrl` returns HTTP 200 and a usable `redirectUrl` — no error at all. Validate the body yourself before sending it.
> 7. Always verify the `X-Paymove-Signature` header on incoming webhooks before trusting them: https://docs.paymove.io/en/webhook-signature.md
> 8. Errors are `{"status": <int>, "message": "<text>"}`. Branch on the HTTP status only — never on `message`, which is unstable and leaks internal class names.
> 9. There is no rate limiting, no HTTP 429, no HTTP 422, no `Idempotency-Key` header and no API versioning. Do not write code that handles them.
> 10. Re-POSTing an `externalId` that already exists returns HTTP 200 with the ORIGINAL `redirectUrl` and silently discards EVERY field you send — the new price, description and details are all ignored. Use `PATCH /api/pay/product/{productId}/subproduct/{externalId}` to change a price.
> 11. Webhooks fire only on `COMPLETED` by default, and `retries` defaults to `0` (no retries) unless you set it explicitly. Delivery counts as successful when the HTTP status equals `expectedCode` — the response body is never inspected.
> 12. Never fulfil an order on the `returnUrl` redirect. The checkout does not redirect there by itself: the customer has to click "back to shop", and inside the widget modal that redirect never happens. Fulfil only in the webhook handler, after verifying the signature.
> 13. Do not pin a version of `@paymove-io/sdk` — install the latest.
