Hi,

Yes, writing a javascript code did solved it. So for those who got into this issue here was how this was solved.

Create an APEX Class to make the external API callout:

Call that APEX class from your custom button.

Now add this custom button on your page layout and your good.

Note: Add handler for the response object on your APEX code as how you would like it handled.
