You posted in the UI end user forums.

@Kathi_at_Intuit at Intuit should give you access to the SDK user group subforum here:

https://accountants.intuit.com/community/user-groups/discussion/03/309

It's actually here:

https://accountants.intuit.com/community/lacerte-sdk-group/gp-p/501

And that second link gives me a blank listing, so I don't know which will work for you.

I'm guessing you have the reference materials, but just in case, here are the linkes:

https://developer.intuit.com/app/developer/lacerte-sdk/docs/lacerte-get-started

https://accountants.intuit.com/support/en-us/help-article/license-information/lacerte-software-devel...

Hope that helps.
