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
