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.
