Replacement of document repository with an independent system with REST API and Outlook add-in

Methodically, work is carried out every four weeks according to customer standards. The documents are stored in a Microsoft SQL database. The REST API is used to retrieve and add the documents and validate the technical context by communicating with the REST API of the central master data application. To do this, endpoints must be added to this application, which then take over the validation. The Microsoft Outlook 365 add-in is based on a dynamically generated HTML page, which then calls the REST API of the document repository to upload the desired document. The conceptualisation was documented in Confluence and adapted using an agile approach.
