Zinc has separate Staging and Production environments with different base URLs. A Partner API key generated in one environment will not work against the other, so pick the environment that matches the key you intend to use.

​
Select the Zinc environment

When creating the Connector Profile, choose the Zinc environment your Partner API key was generated in. This drives which Zinc base URL StackOne sends requests to.

  • Select Staging if your key was generated at https://stagingapp.zincwork.com/. Requests are routed to https://stagingapi.zincwork.com/partner/v2.
  • Select Production if your key was generated at https://app.zincwork.com/. Requests are routed to https://api.zincwork.com/partner/v2.
  • The Environment value cannot be changed after the Connector Profile is created — create a separate Connector Profile per environment if you need both.

​
Understanding environments

Zinc provides separate Staging and Production tenants for development and live operations. They are fully isolated: accounts, candidates, packages, and API keys do not cross between them.

1

Staging environment

Use Staging for development, integration testing, and QA validation without running real background checks.

  • Sign-in URL — https://stagingapp.zincwork.com/
  • API base URL — https://stagingapi.zincwork.com/partner/v2
  • Use case — Build and validate your integration before going live.
2

Production environment

Use Production for live integrations that submit real background checks against real candidates.

  • Sign-in URL — https://app.zincwork.com/
  • API base URL — https://api.zincwork.com/partner/v2
  • Use case — Live production traffic with real candidate data and billable checks.
