# Application API Key

The API should only be interacted with by the React application server-side. You will need to authenticate the React application using the API Key below:

<table><thead><tr><th>NAME</th><th>VALUE</th></tr></thead><tbody><tr><td>X-Application-API-Private-Key</td><td><pre><code>940921de7d6d42290b57c9a5504a10da6de81eb4feab60adbd3bb4f54c28cbdd
</code></pre></td></tr><tr><td>X-Application-API-Public-Key</td><td><pre><code>7296bbcdd0e83b6cb3c7f905fee43b088266bf297a3fc210a844f52f78a18537
</code></pre></td></tr><tr><td>X-Application-Forwarded-Client-IP-Address</td><td>{User IP Address}</td></tr><tr><td>X-Application-Forwarded-Client-User-Agent</td><td>{User UA}</td></tr></tbody></table>
