Authentication: OAuth 2.0 of API-keys

  • Shifts (time tracking) and payroll supplements

What a Factorial integration does

What to watch for

  • Contracts are stored as versions with an effective date. For payroll we read the version that applies to the payroll period.
  • The API version is part of the path. When a new version appears we test the integration before switching.

In your IT landscape

  • Runs as a managed integration on the KoppelHet platform, next to your existing integration layer. No VPN into your network.
  • Only the fields in the design you approve are transferred. The platform keeps no register of its own.
  • Tested first in the test or acceptance environment where there is one. You choose the go-live moment.
  • ISO 27001 certified, hosted in Amsterdam. When the contract ends you receive the configuration and the audit logs.
