## Verdicts

**Ecwid by Lightspeed.** The REST API has 40 access scopes, a published limit of 600 requests a minute per token with `Retry-After` on a 429, field selection through `responseFields`, and Markdown docs with an llms.txt index. Tokens never expire, there is no test mode or idempotency key, API access needs a paid plan, and carts are built only in the browser.

**Saleor API + MCP.** One GraphQL schema with 78 typed error-code enums and 464 marked deprecations. The MCP server can't create checkouts or orders.

## Before you call either

### Ecwid by Lightspeed

1. Send the token as `Authorization: Bearer` to `https://app.ecwid.com/api/v3/{storeId}`. Tokens in the query string stopped working in March 2025
2. Use the secret token server-side only. The public token reads enabled products and places orders that are not marked paid
3. Add `responseFields`, for example `total,items(id,name,price)`, to keep responses small, and page with `offset` and `limit` (maximum 100)
4. Stay under 600 requests a minute per token and wait the `Retry-After` seconds on a 429. Repeated calls with a bad token get the token and IP blocked for longer
5. Work in a separate test store. There is no test mode, and `POST /orders` writes a real order with no idempotency key
6. After changing an app's scopes, uninstall and reinstall it, then replace the stored tokens. The old ones stop working

### Saleor API + MCP

1. Pass the channel slug on product and checkout queries. Prices and availability are per channel
2. Send X-Saleor-API-URL and X-Saleor-Auth-Token on every MCP request, with a token holding MANAGE_PRODUCTS and MANAGE_ORDERS
3. Read the `errors` array in every mutation payload. A 200 response can still carry a CheckoutErrorCode
4. Keep queries under the 50,000 complexity cap and 100 items a page, and send at most 4 mutations per request
5. The 3.24 changelog removes the old dummy payment plugins, so test checkouts should use a payment app
