Capture Requests: Body is cryptic but is should be JSON


I’m trying to reverse engineer an API and I did it successfully with the GET Requests. For the POST and PUT request, I can see the response without issues, but the request body is encrypted somehow. I’ve attached a screenshot. I have no clue where this comes from nor how to try to decrypt it. The content-type is actually JSON on the request.

Edit: Sorry, I forgot to mention that this is a iOS app and i’ve set up a proxy to port 5555, to capture the requests within postman.

I would really appreciate any help!
