## Which one, for what

### Odoo External API (C)

Good for: An agent working inside a company that already runs Odoo, where invoices, bills, journal entries, stock and sales sit in one database behind one endpoint pattern.

Ahead on:
- Security & auth, 61 against 36
- Maintenance & community, 73 against 62
- Transparency & trust, 93 against 48

Also in its favour:

Watch for: On Odoo Online the external API is limited to the Custom plan. One App Free and Standard exclude it

### Rutter Accounting API (C)

Good for: Lenders, spend-management and fintech products that read ledgers alongside commerce and payment platforms, and that need writes an agent can retry safely.

Ahead on:
- Reliability, 67 against 44
- Schema & documentation, 79 against 51

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: Production prices are quote-only

## Verdicts

**Odoo External API.** One endpoint pattern reaches every model, with field selection, filters and paging, and keys that expire within three months. On Odoo Online the external API needs the Custom plan, there is no OpenAPI file, and the acceptable use policy asks for about one call a second with no parallel calls.

**Rutter Accounting API.** Idempotency-Key header on writes, and prefer_sync writes that fall back to async after 30 seconds. Production prices are quote-only.

## Before you call either

### Odoo External API

1. POST to `/json/2/<model>/<method>` with `Authorization: bearer <key>` and named arguments in a JSON body. Add `X-Odoo-Database` when one host serves several databases
2. Pass `fields` and `limit` on `search_read`. The default limit is every matching record
3. Create invoices and bills on `account.move` with `move_type` set to `out_invoice` or `in_invoice`, then call `action_post`. A new move is a draft
4. Keep to about one call a second with no parallel calls on Odoo Online, and batch records into one `create` call
5. Ask the owner for a key on a dedicated bot user with the minimum access rights, and rotate it before its expiry date

### Rutter Accounting API

1. Send X-Rutter-Version: 2024-08-31 on every call
2. Send an Idempotency-Key on every create so a retry after a timeout doesn't write twice
3. Use response_mode=prefer_sync and handle the 202 async_response anyway
4. Treat 452 as the ledger throttling you and 429 as Rutter's 500-per-10-seconds organisation limit
5. Keep access_token out of logged URLs. The docs only show it as a query parameter
