I installed this in Lifetime to test this component out and was met with many integration 404 errors such as:

https://www.mydomain.net/PropertiesServices/rest/ModuleServices//Module_GetSharedSitePropertiesList

The error is of course due to the double "//" between ModuleServices and Module_GetSharedSitePropertiesList path names.

In the OnBeforeRequest of the ModuleServices API, you are setting the CustomizedRequest.BaseURL = Protocol + "://" + Hostname + "/PropertiesServices/rest/ModuleServices/"

The BaseURL is then prepended to the method path, such as:

/Module_GetSharedSitePropertiesList?ModuleKey={ModuleKey}&SearchKeyword={SearchKeyword}&OnlyActive={OnlyActive}&Hostname={Hostname}&Protocol={Protocol}

As a result, you end up with double "//" in the full URL.

The quick solution for me was to remove the trailing "/" in the CustomizedRequest.BaseURL.  

Pointing this out for anyone else that attempts to use this component; and hopefully fixed by the team.
