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.

QuickBooks Online API + MCP

Official MCP server from Intuit with 145 tools and flags to remove write, update or delete tools. Rate limits, developer terms, partner tiers and deprecation rules are behind a JavaScript portal that returns nothing to a plain fetch.

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

QuickBooks Online API + MCP

  1. Store the realmId with the tokens. Every URL needs it and the token alone doesn't name the company
  2. Persist the new refresh token from every refresh response. The previous one expires 24 hours later
  3. Use the query endpoint with MAXRESULTS and STARTPOSITION for reads rather than fetching by id
  4. Send a unique requestid query parameter on writes, so a retry returns the first response instead of posting twice
  5. On 429, wait for Retry-After before retrying, and don't retry other 4xx errors
