## Which one, for what

### PayFit (C)

Good for: An agent working for an employer that already runs payroll on PayFit in France, the UK or Spain and needs employees, contracts, payslips, absences or the payroll journal.

Ahead on:
- Reliability, 79 against 25
- Schema & documentation, 78 against 71
- Agent ergonomics, 51 against 44
- Transparency & trust, 70 against 48

Also in its favour:
- No incidents deducted, where Worklio loses 3 points for them

Watch for: No operation runs, previews or approves a payroll. The API reads payroll status, payslips and accounting exports

### Worklio (E)

Good for: A software platform, PEO or payroll bureau that wants to sell US payroll under its own brand and can sign a partner agreement, with Worklio handling tax filing and money movement.

Ahead on:
- Payments & pricing, 25 against 10

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No rate limits, 429 handling or idempotency keys were found in the reviewed documentation

## Verdicts

**PayFit.** A public OpenAPI 3.0 file, llms.txt and scoped keys let a paying customer's agent read payroll outputs and write absences. The API cannot run or approve a payroll, new partner integrations are not being accepted, and no idempotency keys or SDKs were found.

**Worklio.** Worklio documents 853 REST operations with an OpenAPI fragment on every reference page, and a developer can register for the sandbox without a sales call. No rate limits or public SDK were found, the status page is password protected, and the payroll guide tells callers to treat an HTTP 500 as the signal to finalise.

## Before you call either

### PayFit

1. Have a company admin create the key at app.payfit.com/integrations/hub/api with only the scopes the task needs. The key is shown once
2. POST the key to `https://oauth.payfit.com/introspect` to get `company_id`, then call `https://partner-api.payfit.com/companies/{companyId}/...`
3. Page lists with `nextPageToken` and `maxResults`, which defaults to 10 and stops at 50
4. Check before repeating a failed POST. There is no idempotency key, and `POST /absences` creates an absence that is already validated
5. A collaborator or contract created through the API stays incomplete until an HR admin finishes it in the PayFit app, and a new contract takes 2 to 5 minutes to appear

### Worklio

1. Send `api-version: 2.0` on `/wep` calls. The reference marks the header as required
2. Get a token from `POST https://api.worklio.com/connect/token` with the password grant and scope `api`. It lasts 24 hours, so fetch a new one daily
3. Run payroll as start, `next` until it answers 500 with "Next step operation is not allowed", then `finalize`. Don't treat that 500 as a failure
4. Don't retry bonus, off-cycle, void or termination payroll starts blindly. The reference says those calls are not idempotent
5. Most `/wep` list endpoints return the whole result set. Paging, `filter` and `sort` work only under `/api/public`, and a `DataToken` expires after 60 seconds
