## Which one, for what

### Codat (B)

Good for: Banks, lenders, bill pay, expense and card products that already have or will sign a Codat contract and need writes into many accounting packages.

Ahead on:
- Reliability, 80 against 71
- Schema & documentation, 77 against 71
- Agent ergonomics, 81 against 51
- Maintenance & community, 75 against 56

Watch for: No public price. The pricing page returns 404 and fees are set in an order form

### Zoho Books (C)

Good for: Small businesses already on Zoho that want an agent to raise invoices, record bills and payments, reconcile bank transactions and post journals with narrow scopes.

Ahead on:
- Security & auth, 68 against 49
- Payments & pricing, 30 against 10

Watch for: No profit and loss, balance sheet or other report endpoint appears in the API docs or the OpenAPI files

## 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.

**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

### 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

### 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
