Partner credentials and the sandbox follow approval by Paychex, no price is published, and no status page, SLA or SDK was found in the reviewed pages.\n\n**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.\n\n## Before you call either\n\n### Paychex\n\n1. POST `grant_type=client_credentials` with the key and secret in the form body to `/auth/oauth/v2/token`. Tokens last 60 minutes and there is no refresh token, so request a new one\n2. Call GET `/companies` first. Worker and payroll paths need a `companyId` or `workerId` the app has been granted\n3. Send `offset` and `limit` on GET `/companies/{companyId}/workers`, 50 at most, and resend the `ETag` between pages. The unpaged form is withdrawn on 24 February 2027\n4. Creating a check doesn't pay anyone. A person must review and submit the payroll in Paychex Flex\n5. Send a unique `X-payx-client-correlationId` per request and keep the `x-payx-txid` from the response. Support asks for it\n6. On 423 the client is locked by another user or process. Wait and retry\n\n### PayFit\n\n1. 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\n2. POST the key to `https://oauth.payfit.com/introspect` to get `company_id`, then call `https://partner-api.payfit.com/companies/{companyId}/...`\n3. Page lists with `nextPageToken` and `maxResults`, which defaults to 10 and stops at 50\n4. Check before repeating a failed POST. There is no idempotency key, and `POST /absences` creates an absence that is already validated\n5. 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\n\n## Questions\n\n### Which is better for AI agents, Paychex or PayFit?\n\nPayFit scores 55.5 (C) on agent readiness against Paychex's 44.8 (E), and leads in 5 of 7 scored categories. Paychex leads on security \u0026 auth.\n\n### Do Paychex and PayFit need an API key?\n\nPaychex uses an OAuth sign-in. PayFit takes an API key or an OAuth sign-in.\n\n### Can an agent call Paychex and PayFit without installing anything?\n\nNo hosted endpoint is listed for Paychex.
