On a schedule the scenario pulls fresh contacts from Keap and pushes them into Telfin customer lists. Retargeting always runs on a current base.
Automating Keap and Telfin takes no code: a ready-made scenario does the routine for you.
You can launch this Keap + Telfin integration in Scriptera: describe the task in plain words — the scenario is built, launched and monitored for you.
