Storing Connect apps data on App Properties via REST API

[Shahryar]

Hey Everyone,

based on this article, I'm trying to store some configuration and simple data on the apps properties.

but no matter how I try, I getting this error over and over:

message: "App with key does not exist."

status-code: 404

Does anyone know how to fix it?

Looks like something with the request header / payload is wrong, but this is very hard to say from your description.

Are you calling from the application backend or from within the browser?

Mind intercepting the rest call and posting it here or sharing some code?
