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.

The Browse API has the following resources: item_summary: Lets shoppers search for specific items by keyword, GTIN, category, charity, product, or item aspects and refine the results by using filters.  (Experimental) search_by_image: Lets shoppers search for specific items by image. You can refine the results by using URI parameters and filters. item: Lets you retrieve the details of a specific item or all the items in an item group, which is an item with variations such as color and size. This resource also provides a bridge between the eBay legacy APIs, such as Trading and Finding, and the RESTful APIs, such as Browse, which use different formats for the item IDs. You can use the Browse API to retrieve the basic details of the item and the RESTful item ID using a legacy item ID.  (Experimental) shopping_cart: Provides the ability for eBay members to see the contents of their eBay cart, and add, remove, and change the quantity of items in their eBay cart.  *Note:* This resource is not available in the eBay API Explorer. The item_summary, search_by_image, and item resource calls require an Application access token. The shopping_cart resource calls require a User access token.
