My question: We have an api endpoint (https) which when tried from postman, we get response but we see an error which says " Unable to verify the first certificate ". Same API endpoint when open in chrome/edge browser , we see no issue with certificate and its shows valid. Can you explain why its showing invalid in postman?

Details (like screenshots):

How I found the problem: unit testing the apis

I’ve already tried: nothing so far.
