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
