The lockally control plane lets integrators and direct customers manage everything except actual mail data flow (which uses standard JMAP / IMAP / SMTP-submission against the data plane endpoints). **Authentication.** All `/v1/_*` endpoints require a Bearer API key in the `Authorization` header. Keys are formatted `lk_live__`, or `lk_test_` for a test key. Create keys in the dashboard, or with `POST /v1/api-keys` using a key that holds `tenant:admin`. The key's plan is checked on every request, so a key stops working if the account moves to a plan without API access, and works again if it moves back. **Errors.** Failures return [RFC 9457](https://www.rfc-editor.org/rfc/rfc9457) `application/problem+json` documents. **Scopes.** Each endpoint requires a specific scope on the presented key. Insufficient scope returns `403` with the required scope name in `detail`.

Build a fully custom headless storefront - your own web app, mobile app, or POS - against a single OE Commerce store. Every endpoint below is namespaced under `/api/v1/store/...`. Building admin/back-office tooling instead? See [/docs/admin](/docs/admin). New here? [/guides/store](/guides/store) walks through getting a key, the anonymous cart session, and calling your first endpoints step by step - this page is the field-level reference to come back to afterward. ## Getting Started 1. Click the **Authorize** button at the top of this page. 2. Provide credentials: - **X-Commerce-Key** (always required) - your store's Store Access Key from Backoffice > Settings > Application APIs. `pk_store_...` (publishable) is safe for browser/mobile code; `sk_store_...` (secret) is server-to-server only and is rejected outright if a browser Origin header is present. - **Bearer** (only for endpoints acting on a specific customer - Account, Orders, Wishlists, etc.) - the token from **Auth > register** or **Auth > login**. Once authorized, you can explore and test all available endpoints directly from this interface. ## Anonymous Carts A guest cart is tracked by an `X-Session-Ref` header, not a cookie - the server generates one on your first request and echoes it back on every response after. Keep sending back whatever value you last received. Logging in carries that same cart forward onto the customer's account automatically, with no separate merge step. ## Errors Failures use RFC 9457 Problem Details (`application/problem+json`) with a stable `code` field for programmatic handling, e.g. `store_key_invalid`, `store_key_revoked`, `store_key_scope_denied`, `rate_limited`. A rejected *business* action (e.g. adding fewer than a product's minimum order quantity to the cart) instead comes back as HTTP 200 with `"success": false` and a human-readable `message` - always check `success` in the body, not just the HTTP status code. ## Rate Limits Requests are limited per Store Access Key (200/minute). The credential-stuffing surface (register/login/forgot-password/reset-password) is limited more tightly per caller IP (10 per 5 minutes). A 429 response includes a `Retry-After` header.
