How to get token from JSON and output to JS?

Question

JavaScript

Good afternoon. The goal is to solve the following problem:

Write an application in JS that receives a token or an error from a json file (will be issued within an hour).

If you have a token, add it to Cookies.
If there is no token, display an error as a notification.

Mandatory condition:
the length of the token is 32 characters, the last character must be the symbol =, the thirteenth and fifteenth - !

How to implement this, just with JSON there is no experience at all?
