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**Salsa.** Salsa is reached as an embedded-payroll partner, not through an employer's existing payroll account. The REST API has a public OpenAPI 3.1 spec with 123 operations, a payroll preview, a separate confirm step and short-lived user tokens limited by role. Access starts with a sales conversation, and no public price, self-serve sandbox, status page or API changelog was found.\n\n## Before you call either\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### Salsa\n\n1. Use the sandbox token against https://api.sandbox.salsa.dev and the production token against https://api.salsa.dev. Each environment has its own token\n2. Call POST /payroll-runs/preview before creating a run, then confirm the PENDING run in a separate call. Confirming starts the employer debit\n3. Send your own externalId on every create. A repeat returns a uniqueness error, which is the only duplicate protection\n4. Make sure externalId values are unique across all employers, since each entity type has one namespace\n5. Mint a user token with the lowest role and the fewest employerIds the task needs, and keep the partner token on the server\n\n## Questions\n\n### Which is better for AI agents, PayFit or Salsa?\n\nPayFit scores 55.5 (C) on agent readiness against Salsa's 46.1 (D), and leads in 5 of 7 scored categories. Salsa leads on security \u0026 auth and maintenance \u0026 community.\n\n### Do PayFit and Salsa need an API key?\n\nPayFit takes an API key or an OAuth sign-in. Salsa needs an API key.\n\n### Can an agent call PayFit and Salsa without installing anything?\n\nNo hosted endpoint is listed for PayFit.
