Verdicts

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.

Zoho Books

The public OpenAPI files cover 885 operations with OAuth scopes per module and operation, and the Free plan allows 1,000 API requests a day. No report endpoint, official SDK, SLA or dated API changelog was found, and the documented token calls put the client secret in the URL.

Before you call either

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

Zoho Books

  1. Send organization_id as a query parameter on every call. Read it from GET /organizations first
  2. Use the api_domain returned with the token, since each of the nine data centres has its own host (zohoapis.com, zohoapis.eu, zohoapis.in and others)
  3. Send Authorization: Zoho-oauthtoken <token> and refresh hourly. Each user keeps at most 20 refresh tokens and the oldest is deleted
  4. Stay under 100 requests a minute and the plan's daily cap. Codes 44, 45 and 1070 on a 429 mean minute, day and concurrency limits
  5. To repeat an update safely, send X-Unique-Identifier-Key, X-Unique-Identifier-Value and X-Upsert with a unique custom field. Creates have no idempotency key
