Sitecore Forms represents new feature introduced in Sitecore 9 and newer versions. It is considered as replacement of WffM, but current situation is still little bit painfull. Some features from WffM are missing, and many behavior aspects are not configurable as they are hardcoded in code provided by Sitecore.
In this article we will cover one of missing features – “Identify Contact” submit action, which allows us simply “Identify” anonymous contacts by filling subscription form.
This article reuses and simplifies scenario used in Sitecore Documentation here.
