Hi,
This SDK's Template constructor/class is missing the attributes require_all_signers and reminders, along with getters & setters for same.
It's necessary to have these available to set these boolean values for a document created from a template with createDocumentFromTemplate.
Interestingly enough, the API docs for Use Template also fail to mention these two parameters (they are only mentioned in the docs for Create Document).
However, they are definitely valid & work as expected when creating a document from a template when interacting with the API directly via HTTP.
Cheers.
