can I add User handle/namespace on my trigger on the workflow?
I want to add a membership type field on my module and add a workflow automation that checks on this field if it has a value. In order to do this, I need to use the User for checking, before/after login, on the record link between the two modules - system user and membership module.
You can see all of the constraints and initial scope variables the trigger defines in the trigger configuration side panel. For the before/after login, IIRC, you get the entire user object so you should have the user handle there. And the namespace, shouldn’t be there, but you can hard-code it in a function/expression step.
What you could consider, if it simplifies things, is to define a user module on your namespace which would serve as a little interface between system users and your other modules.
