.net developer for m-files plugin

this is the requirements of job , we need a plugin that will provide invoice information exchange between the api and m-files invoices ( sending invoice info to receive a qrcode and parse this qrcode in m-files invoice file to print it later by the user ) so you will need to make a plugin that will let the user authenticate with the api and store auth token to use it in authenticated api request after that we need to make new table to store egs units informations and token to use it later in sending invoice information , egs units are the same as sell points so every sell point will generate a sequential invoices , the api url is ( facturia.up.railway.app ) this is the api link , in the main page you will find some docs alongside with a flowchart ( maybe the flowchart looks complex but i redesign it in figma , i will share the link later ) and you will find a postman collection that will help you in simulating api requests , also the examples that we need are more simpler then the example you will find in postman because the postman collections contains a full invoice information while we need a few , if you are interested replay with the potential time and price
