You can create a link for users to upload a new document:
hylandmobile://launch?appid=onbase-mobile&path=upload%3Fdtid%3D202&kw276%3D123&kw170%3DVendor1&kw170%3DVendor2&kw273%3D2020-09-17
The path is constructed by specifying values for Document Type (dtid) and Keyword Type (kw) parameters for indexing the document. At a minimum, a Document Type must be specified. Additionally, once the path value is constructed, it must be URL encoded in order for the link to execute successfully.
