Adding a custom form to a project via API V4

[RickVa1]

How can I associate an additional custom form with a project via API V4? I can't find a way to access the collection of forms, but only the primary form, via categoryID. I'm concerned that a PUT with &updates={'categoryID':'$newCategory'} would overwrite the existing primary form association rather than add to the category list/collection. Feel free to suggest a specific solution in a higher version if this can't be done in V4, but I most need a quick solution compatible with V4 if one exists. Thanks! Rick Van Surksum Altice USA

I'm trying to access the Project Details (fields on the overview tab) using the API in visual Studio.net. i downloaded the sample .NET app and got it to work listing all projects. i just need to get the details for each project. anyone have a solution or example? this is the first time using the API. Dim projects As JToken = client.Search(ObjCode.PROJECT, New With {Key .groupID = userGroupID}) this command gets me all the current projects. thanks
