# Connect Open Library with User-Agent – StackOne Hub

> Link a Open Library account in the StackOne Hub using User-Agent. End-user guide to authorize the integration and start using Open Library actions.

<section data-guide-section data-guide-scopes="">
  <h2>Creating Your User-Agent</h2>

  <p>Open Library asks every API client to identify itself with a User-Agent header. You create this value yourself; it is not issued by Open Library.</p>

  <Steps>
    <Step title="Format your User-Agent string">
      <div data-guide-step data-guide-scopes="" data-guide-display-scopes-list="">
        <p>Combine your application name with a contact email address in parentheses.</p>

        <ul>
          <li>Format: `AppName (contact@example.com)`</li>
          <li>Example: `AcmeBooksBot (admin@acme.com)`</li>
          <li>Open Library uses this to identify your traffic and apply per-client rate limits (identified clients get higher limits than anonymous ones)</li>
          <li>A missing or generic value may cause your requests to be throttled or blocked</li>
        </ul>
