Which one, for what

Finch BB

Good for An application that needs to read employees, pay runs and pay statements from whatever payroll or HR system an employer already uses, or to write benefit deductions back.

Ahead on

  • Reliability, 84 against 79
  • Schema & documentation, 87 against 78
  • Agent ergonomics, 71 against 51
  • Security & auth, 66 against 51
  • Payments & pricing, 30 against 10
  • Maintenance & community, 84 against 28

Also in its favour

  • Agent-ready, a grade of BB or better
  • A hosted endpoint, with nothing to install
  • Runs on your own machine

Watch for

Finch cannot create, preview or approve a payroll. Writes are limited to deductions and contributions, on Pro and Premier plans

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.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

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

Verdicts

Finch

Graded on the REST API. An employer grants each connection named product permissions, and limits, error codes and a 99.9 per cent uptime SLA are published. Finch reads payroll and writes deductions but cannot run a payroll. Access tokens never expire, no idempotency keys were found, and writes and most providers need a sales-led plan.

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.

Before you call either

Finch

  1. Send Finch-API-Version: 2020-09-17 and Authorization: Bearer <access_token> on every request. A request without the version header fails with 400
  2. Call GET /introspect first to see the connection's products, status and whether it is automated or assisted before choosing endpoints
  3. Treat a 202 response as data not ready, not as data. Retry with backoff, and expect up to 14 days for an assisted connection's first sync
  4. Stay under 20 requests a minute on organisation endpoints and 12 on pay endpoints across all tokens. Batch IDs, and on 429 wait 60 seconds
  5. After a deduction write, poll the job by job_id until it completes before enrolling individuals. Enrolment overwrites an existing enrolment
  6. Start the MCP server with --code-allow-http-gets or a token without the benefits product when only reads are intended

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
