## Which one, for what

### Fabric (E)

Good for: A merchant-side API for retailers already on Fabric's order management, catalogue or dropship products.

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where Spree Commerce loses 5 points for them

Watch for: No public price, free tier or self-serve signup. A trial account is arranged with Fabric

### Spree Commerce (BB)

Good for: Teams that want to own a Rails commerce backend with marketplace, B2B and multi-region functions and drive it through REST.

Ahead on:
- Reliability, 82 against 23
- Schema & documentation, 85 against 79
- Agent ergonomics, 90 against 57
- Payments & pricing, 55 against 0
- Maintenance & community, 81 against 15
- Transparency & trust, 60 against 55

Also in its favour:
- Agent-ready, a grade of BB or better
- Open source

Watch for: Six GitHub security advisories between 8 January and 20 July 2026, four rated High, most of them access-control flaws on guest carts, orders and addresses

## Verdicts

**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.

**Spree Commerce.** A self-hosted BSD 3-Clause platform with public OpenAPI files for the Store and Admin APIs, scoped secret keys, documented rate limits and idempotency keys on cart and checkout calls. GitHub lists six security advisories between January and July 2026, four rated High, and the default docs describe the 6.0 release candidate while 5.6.1 is the stable release.

## Before you call either

### 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

### Spree Commerce

1. Send a publishable key in `X-Spree-Api-Key` on every Store API call. Add `X-Spree-Token` with the cart token for guest carts, or a customer JWT as a Bearer token
2. Send `Idempotency-Key` with the cart token or a customer JWT on cart, payment and completion calls. A request carrying only the publishable key is never cached
3. Ask for `fields` and `expand` explicitly. Relations are left out by default and `limit` stops at 100
4. Use a secret key with the narrowest scopes for the Admin API. `read_all` gives a read-only key, and the CLI's auto-minted local key is read-only
5. Read the docs under `/docs/v5` for a 5.6 store. The default docs describe 6.0, which renames shipments to fulfilments and splits carts from orders
