# Zinc API Key connector profile – StackOne setup guide

> Set up the API Key connector profile for Zinc in StackOne. One-time admin setup required before your users can link Zinc accounts via Hub.

<Warning>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.</Warning>

<section data-guide-section data-guide-scopes="">
  <h2>Select the Zinc environment</h2>

  <p>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.</p>

  <ul>
    <li>Select <strong>Staging</strong> if your key was generated at <a href="https://stagingapp.zincwork.com/" target="_blank" rel="noopener noreferrer">[https://stagingapp.zincwork.com/](https://stagingapp.zincwork.com/)</a>. Requests are routed to `https://stagingapi.zincwork.com/partner/v2`.</li>
    <li>Select <strong>Production</strong> if your key was generated at <a href="https://app.zincwork.com/" target="_blank" rel="noopener noreferrer">[https://app.zincwork.com/](https://app.zincwork.com/)</a>. Requests are routed to `https://api.zincwork.com/partner/v2`.</li>
    <li>The <strong>Environment</strong> value cannot be changed after the Connector Profile is created — create a separate Connector Profile per environment if you need both.</li>
  </ul>

  <h2>Understanding environments</h2>

  <p>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.</p>

  <Steps>
    <Step title="Staging environment">
      <div data-guide-step data-guide-scopes="" data-guide-display-scopes-list="">
        <p>Use Staging for development, integration testing, and QA validation without running real background checks.</p>

        <ul>
          <li><strong>Sign-in URL</strong> — <a href="https://stagingapp.zincwork.com/" target="_blank" rel="noopener noreferrer">[https://stagingapp.zincwork.com/](https://stagingapp.zincwork.com/)</a></li>
          <li><strong>API base URL</strong> — `https://stagingapi.zincwork.com/partner/v2`</li>
          <li><strong>Use case</strong> — Build and validate your integration before going live.</li>
        </ul>
      </div>
    </Step>

    <Step title="Production environment">
      <div data-guide-step data-guide-scopes="" data-guide-display-scopes-list="">
        <p>Use Production for live integrations that submit real background checks against real candidates.</p>

        <ul>
          <li><strong>Sign-in URL</strong> — <a href="https://app.zincwork.com/" target="_blank" rel="noopener noreferrer">[https://app.zincwork.com/](https://app.zincwork.com/)</a></li>
          <li><strong>API base URL</strong> — `https://api.zincwork.com/partner/v2`</li>
          <li><strong>Use case</strong> — Live production traffic with real candidate data and billable checks.</li>
