This package provides a node for Node-RED to access the Automatische Abholung of Mein Postkorb of the Austrian Unternehmensserviceportal (see references). You can retrieve new or all deliveries (Nachrichten) and you can close a delivery (mark it as not new).
npm i @vrilcode/node-red-uspmp
You can use this package also with your regular JS/TS application without Node-RED. An example code is provided in contrib/uspmp-client.mjs, which can be executed via npm run client, if an according .env file exists.
