JWT does not work in live but works in postman?

Hi, So I tried a few post/get requests using JWT and it worked using Postman app, but when I tried using the same JWT token in a live app, it fails.

I also tried using oath 2.0 but I was not able to get passed step 2, getting the web token.

Any help would be appreciated. Thanks.

Hey @zkegs

Thanks for using the dev forum!

Have you tried to update o the latest version of Zoom, Zoom 1.8.3? This may be the problem.


Hey @zkegs,

Can you share a copy of the request/response you’re using so that we can help debug? If you’re able to get the request to work in Postman, please double check that you’re passing all of the same headers and authentication parameters in your code.

Hey @zkegs,

Thank you for providing additional information. It looks like this is happening because you are using a Content-Type of application/xml when this endpoint only supports JSON. In my requests, I typically don’t supply a Content-Type header and based on the JSON body that the server gets, it’s able to respond as expected. If the tool/server you are using to make the request is setting this header, I would override it with the value application/json.

Let me know if you have any questions.


Yep, it works now. Thanks much for the help.
