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.\n\n## Before you call either\n\n### FreeAgent API\n\n1. Store the new refresh token from every refresh response. The old one stops working\n2. Create the invoice, then PUT /v2/invoices/:id/transitions/mark_as_sent. A draft isn't visible to the customer\n3. Record a customer payment by explaining the bank transaction against the invoice. There's no invoice payments endpoint\n4. Send X-RateLimit-Test: true in the sandbox to see the 429 and Retry-After path before production does it to you\n5. Use view= and updated_since= on list calls and per_page up to 100 to stay under 120 requests a minute\n\n### Odoo External API\n\n1. POST to `/json/2/\u003cmodel\u003e/\u003cmethod\u003e` with `Authorization: bearer \u003ckey\u003e` and named arguments in a JSON body. Add `X-Odoo-Database` when one host serves several databases\n2. Pass `fields` and `limit` on `search_read`. The default limit is every matching record\n3. 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\n4. Keep to about one call a second with no parallel calls on Odoo Online, and batch records into one `create` call\n5. Ask the owner for a key on a dedicated bot user with the minimum access rights, and rotate it before its expiry date\n\n## Questions\n\n### Which is better for AI agents, FreeAgent API or Odoo External API?\n\nFreeAgent API scores 57.2 (C) on agent readiness against Odoo External API's 55.9 (C), and leads in 2 of 7 scored categories.
