post existing JSON

[MaikelTK]

Hello,
I am creating a project where I use an ESP32 to read multiple sensor values.
Currently I use the arduinojson library to put all the data I need into a json file.

A) Is it possible to use the aRest library with this json file I already created? If so, how?
B) Or is it possible to create a json file with the aRest library and add multiple values to it?
For example I tried some of the aRest example code to GET an integer value through the postman application. But I can only get 1 integer from the GET command and I need to get more.

Any help would be appreciated, this is my first time working with JSON and REST.

you could save the JSON as a string in a variable and then expose it with rest.variable("data", jsonstring)
