RevKeen is a fintech-grade API for payments, subscriptions, invoices, and billing. The canonical production MCP server is available at `https://mcp.revkeen.com/mcp`. **API Version:** `2026-05-01` — Pin with the `RevKeen-Version` header. **Quick Links:** [Full Documentation](https://docs.revkeen.com) | [Authentication](https://docs.revkeen.com/authentication) | [OAuth](https://docs.revkeen.com/oauth) | [SDKs](https://docs.revkeen.com/sdks) | [Webhooks](#webhooks) | [MCP Guide](https://docs.revkeen.com/mcp) ## Authentication Two authentication methods are supported: ### API Keys (recommended for server-to-server REST API integrations) Send your API key in the `x-api-key` header. Get keys from the [Dashboard](https://app.revkeen.com/settings/api-keys). Use `rk_sandbox_*` for test mode and `rk_live_*` for production. ### OAuth 2.1 (recommended for MCP and third-party integrations) Use OAuth 2.1 with PKCE for authorization code flow or client credentials for server-to-server. Tokens are sent via `Authorization: Bearer rk_oauth_*`. See the [OAuth guide](https://docs.revkeen.com/oauth) for setup. - **Authorization Code + PKCE** — user-facing integrations, MCP hosts - **Client Credentials** — server-to-server, automated workflows - **Dynamic Client Registration** — MCP hosts that auto-register ## MCP Integration RevKeen's canonical production MCP server is `https://mcp.revkeen.com/mcp` using Streamable HTTP and OAuth 2.1 bearer tokens. - **Customer launch surface** — read-first customer v1 tools with least-privilege scopes - **Host setup guide** — see the [MCP guide](https://docs.revkeen.com/mcp) for ChatGPT, Claude, and compatible MCP hosts ## API Key Scopes Scopes follow `{resource}:{action}` format (e.g., `invoices:read`, `customers:*`).

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.
