title: Can you make external API requests from Firebase so all API requests are done in the backend if your stack utilizes just React and Firebase?
body: <p>I am a newbie front end developer with no backend experience so please be patient with me.</p>
  
  <p>I currently have a stack utilizing React and Firebase. I would like to make API requests to external sources such as Etsy or Twitter. I cannot make the requests from the front end side (React) for two reasons:</p>
  
  <ol>
  <li><p>In order to do the GET request, a lot of APIs require you to get a key. If I do these API requests on the front end, I believe my key will be exposed.</p></li>
  <li><p>I will most likely get a CORS error.</p></li>
  </ol>
  
  <p>So my question is, can I do API requests from the Firebase side so that all the API requests are done in the backend? If so, what component of Firebase would allow for this capability? If not, what do I need to add to my stack without having to implement an entire backend structure in order to do these API requests?</p>
  
  <p>Thank you very much for your time!</p>
