It is necessary to make the integration of the cash register

It is required to integrate the Frontol cashier and the loyalty program via API.
These two systems have an open API. The plugin must receive requests from the Priority FRONTOL API and pass it to the loyalty program API.
Approximately the following operation of the plugin:
- the plugin itself is placed on the server of the loyalty program. There are settings
- when there is a request from the Frontol cashier, the plugin processes the request, authorizes it and (depending on the incoming request) sends the request to the loyalty program via API
- the plugin receives a response from the loyalty program and forms a response to the request to the Frontol cashier
There is documentation on the API of the loyalty program
During the discussion, I will send a description of the proposed operation of the plugin with examples of requests to the API and a description of the Frontol API
