## Verdicts

**Xero API + MCP.** Granular OAuth scopes, such as accounting.reports.profitandloss.read, required for apps created from 29 April 2026. Developer docs, including the per-minute rate limits, only render with JavaScript.

**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

### Xero API + MCP

1. Send xero-tenant-id on every call. The token alone doesn't name the organisation
2. A bill is an Invoice with Type ACCPAY, a sales invoice is ACCREC. There's no separate bills endpoint
3. Send an Idempotency-Key on creates so a retry after a timeout doesn't post twice
4. Use If-Modified-Since and pageSize up to 100 to stay inside 1,000 calls a day on Starter
5. Set XERO_SCOPES to read scopes only when the agent shouldn't write. The MCP still lists its write and delete tools

### 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
