## Which one, for what

### Codat (B)

Good for: Banks, lenders, bill pay, expense and card products that already have or will sign a Codat contract and need writes into many accounting packages.

Ahead on:
- Reliability, 80 against 44
- Schema & documentation, 77 against 51
- Agent ergonomics, 81 against 67

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No public price. The pricing page returns 404 and fees are set in an order form

### 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 49
- Payments & pricing, 22 against 10
- Transparency & trust, 93 against 71

Also in its favour:
- Open source

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

## Verdicts

**Codat.** Public OpenAPI specs, an Idempotency-Key header on writes, Retry-After on 429 and a written three-month deprecation notice suit an agent that retries. Access is the limitation. No price or self-serve signup is published, the general Accounting API is closed to new clients, and API keys carry no scopes.

**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.

## Before you call either

### Codat

1. Send `Authorization: Basic <base64 of the API key>` to https://api.codat.io. The Portal shows the ready-made header value
2. Send a new GUID as `Idempotency-Key` on every POST and PATCH, and reuse the same key when retrying after a 429
3. Treat writes as asynchronous on most APIs. Keep the push operation key and wait for the `{dataType}.write.successful` or `.unsuccessful` webhook
4. Call the Get model (options) endpoint for the connection before a create or update, because required fields differ by accounting package
5. Filter with `query=modifiedDate>...` and keep `pageSize` at 100. The daily quota is 1,000 requests times one plus the number of active connected companies

### 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
