## 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.

**Fabric.** Public OpenAPI files for about 980 operations, llms.txt, client credentials with role-limited system apps, and a published 99.9 per cent SLA. Access needs a sales contract, with no public price or self-serve trial. The commerce docs are labelled legacy, the newest release notes date from July 2025, and no status page was found.

## 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

### Fabric

1. Get the tenant ID and a System App client ID and secret from the merchant's Copilot admin, with the narrowest role the task needs
2. Request a new system token from {authURL}/v1/token every 10 minutes, since system apps receive no refresh token
3. Send x-fabric-tenant-id on every call, and x-fabric-channel-id where the merchant sells in more than one channel
4. Page order searches with offset and limit, because the default response returns 10 orders
5. Read errorCode and context.endpoint in Orders and Inventory errors, and check for duplicates before retrying a write
