              <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>
