How to make a API Call to Heroku from Chrome Extension

Hi Dev,

So, I am stuck here trying to make this API Call to a Heroku project from a Chrome Extension I am developing.

I am familiar with Flask and NodeJs.
I understand this has something to do with headers somewhere.
I tried searching but could not find a point solution.

Help me solve this problem.

Thanks in advance,

Hi Erick,

Thanks for responding.
I have seen this document but I don't know how to solve the problem. I have been able to use some APIs freely. This occurs only with my Heroku App. I want to know how the other websites are handling this problem. It will be great if you can explain this to me in a development point of view

You were a lot of help. Thanks again 😊.
