        <h1>Developers</h1>
        <p>Outline is built on an open, best-in-class, API</p>
      </Header>
      <Container>
        <p>
          As developers, it’s our mission to make the API as great as possible.
          While Outline is still in public beta, we might make small
          adjustments, including breaking changes to the API.
        </p>
        <h2>Making requests</h2>
        <p>
          Outline’s API follows simple RPC style conventions where each API
          endpoint is a method on{' '}
          <code>https://www.getoutline.com/api/&lt;METHOD&gt;</code>. Both{' '}
          <code>GET</code> and <code>POST</code> methods are supported but it’s
          recommeded that you make all call using <code>POST</code>. Only HTTPS
          is supported in production.
        </p>

        <p>
          For <code>GET</code> requests query string parameters are expected
          (e.g.
          <code>/api/document.info?id=...&token=...</code>). When making{' '}
          <code>POST</code> requests, request parameters are parsed depending on{' '}
          <code>Content-Type</code> header. To make a call using JSON payload,
          one must pass <code>Content-Type: application/json</code> header:
        </p>

        <p>
          <strong>Example POST request:</strong>
        </p>
        <pre>
          <code>
            {`curl https://www.getoutline.com/api/documents.info
  -X POST
  -H 'authorization: Bearer API_KEY'
  -H 'content-type: application/json'
  -H 'accept: application/json'
  -d '{"id": "outline-api-NTpezNwhUP"}'
`}
          </code>
        </pre>

        <p>
          <strong>Example GET request:</strong>
        </p>
        <pre>
          <code>
            {`curl https://www.getoutline.com/api/documents.info?id=outline-api-NTpezNwhUP&token=API_KEY
`}
          </code>
        </pre>

        <h2>Authentication</h2>

        <p>
          To access private API endpoints, you must provide a valid API key. You
          can create new API keys in your{' '}
          <a href={`${process.env.URL}/settings`}>account settings</a>. Be
          careful when handling your keys as they give access to all of your
          documents.
        </p>

        <p>
          To authenticate with Outline API, you can supply the API key as a
          header (<code>Authorization: Bearer YOUR_API_KEY</code>) or as part of
          the payload using <code>token</code> parameter. If you’re making{' '}
          <code>GET</code> requests, header based authentication is recommended
          so that your keys don’t leak into logs.
        </p>

        <p>
          Some API endpoints allow unauhenticated requests for public resources
          and they can be called without an API key.
        </p>

        <h2>Errors</h2>

        <p>
          All successful API requests will be returned with <code>200</code>{' '}
          status code and <code>ok: true</code> in the response payload. If
          there’s an error while making the request, appropriate status code is
          returned with the <code>error</code> message:
        </p>

        <pre>
          <code>
            {`{
  "ok": false,
  "error: "Not Found"
}
`}
          </code>
        </pre>
