I have created Sendable DE and I have created form on landing page. When user fill that form then data from that fields are inserted into my created DE using post method and AMp Script.
User will select care center and interested product in the form and we want to initialize journey builder and our goal will be : he should do registration for that product.
I have started to build journey. I have selected entry point is API and then select my DE and select contact filter as event data (Email not equal to null).
Should I create contact attribute and linked to DE? I want to send an automated email to the person who email is in DE after they submit the form.
