Why Does My API Work in Browser but Return 406 in Postman?

Hi Everyone,

I’m running into a 406 Not Acceptable error while testing my REST API in Postman. Interestingly, the same API works just fine when accessed through a browser, but fails in Postman.

I’ve already played around with the Accept headers — tried application/json, text/html, and a few others — but no luck so far.

A developer friend shared a blog post that gives a good overview of what a 406 error typically means. It was helpful for general understanding, but it didn’t quite address my specific issue with Postman.

Has anyone experienced something similar? Could this be a Postman-specific behavior, or might it be something off in my server config? I’d love to hear your thoughts or suggestions — even just a sanity check to see if I’m overlooking something obvious.

Thanks in advance!
