Provide an .hduploadconfig File
Information about your host application's upload page (URL, etc.) can be distributed to template authors via a simple configuration file distributed from your host application. When the end user clicks on a link to one of these configuration files, HotDocs will auto-configure the Cloud Upload plug-in to include your host application as an upload destination.
An .hduploadconfig file can have any base file name (such as myhostapp.hduploadconfig, config.hduploadconfig, etc.). Internally it is a plain text file consisting of two lines. The first line is the "friendly name" of your host application or upload page. The second line is the URL of your upload page (HTTPS protocol recommended). The file should use a CR/LF line break (\r\n). For example:
My Host App https://www.myhostapp.com:443/Templates/Upload
This works because HotDocs Developer is registered with the operating system (at install time) to handle .hduploadconfig files. If for any reason a user has difficulty using the configuration file, upload sites can be added manually within the Upload plugin by right-clicking on a template or folder within your HotDocs library, selecting Upload > Edit Upload Sites..., and then clicking the Add button.
Once configured to point at your upload page, the Cloud Upload plug-in makes it a simple matter to upload template packages.
