Is it possible to add a customer to a list (a customer who is already part of our main list being added to a specific secondary list) based on a trigger in flows?
I have a couple uses for this, which is why the vague information. One more specific use case:
I have an existing list of customers in our membership program list, and want to add anyone who purchases a particular product (the membership) in our store to this list. Is this possible? These customers would already be registered to our site and signed up to our main list.
