Two authentication modes are supported: - **API key.** Per-org bearer token issued from Settings → API keys (`pk_live_…` / `pk_test_…`). Right choice for direct integrations, single-tenant POS adapters, and back-office sync. - **OAuth 2.0.** Three-legged authorization-code flow with PKCE, for marketplace listings (Square App Marketplace, Shopify App Store, Toast Partner Marketplace, Lightspeed). The merchant installs your app from the partner marketplace, lands on `/oauth/authorize`, approves the requested scopes, and your server exchanges the code at `/api/oauth/token` for a short-lived access token. See the dedicated OAuth section below. Every endpoint is scoped, rate-limited, and idempotent on POST. POS-adapter builders should start with the `/marketplace/*` endpoints — they collapse the typical "find-or-create customer + enrolment + post transaction" flow into a single round-trip with permanent dedupe via `external_transaction_id`. ## Test credentials Test credentials (`pk_test_…` or OAuth applications in TEST mode) can read API data, create isolated test transactions, and simulate wallet pushes. They cannot create, update, or delete live customers, enrolments, or webhook configuration. Test calls to `/marketplace/accrue` only work with an existing customer and enrolment; `/marketplace/enroll` is live-only. This prevents a sandbox integration from changing live customer records. Copy-paste cURL recipes are published at `/api/v1/curl-recipes.md` for teams that want to test the API before wiring the SDK. ## Response headers (universal) Every response, success or error, carries: - **X-Request-Id** — unique per request. Echo this in support tickets; we can find the exact call in the per-key audit log. - **X-API-Version** — date-versioned schema marker (`2026-05-04` as of writing). 12-month deprecation policy. - **X-RateLimit-Limit** — per-minute quota for the credential. - **X-RateLimit-Remaining** — tokens left in the current window. - **X-RateLimit-Reset** — unix-seconds when the window refills. - **Retry-After** — emitted on 429 only; seconds to wait. The reusable error responses below (`Unauthorized`, `Forbidden`, `NotFound`, `RateLimited`, `ValidationError`) declare these as strongly-typed `headers` so codegen against an error path has them. Success responses inline their `"200"` / `"201"` and rely on this convention rather than per-endpoint header declarations. contact: name: Perkstar url: https://perkstar.co.uk servers: - url: https://dashboard.perkstar.co.uk/api/v1 description: Production security: - bearerAuth: [] paths: /locations: get: tags: - Locations summary: List locations operationId: listLocations parameters: - $ref: '#/components/parameters/Cursor' - $ref: '#/components/parameters/Limit' - in: query name: externalVendor description: | Filter to a specific POS vendor (e.g. `square`, `toast`, `lightspeed`, `clover`, `aloha-cloud`). schema: type: string - in: query name: externalLocationId description: | Filter by the vendor-side location id the operator linked in their integrations admin UI.
