Thank you for your response Sathees,
I've used collections and I'm able to see the fields in the transactional email but the values(Product type, Product name, Model/Product code, Date of purchase) are not populated into the email somehow when I test the email. I tried mapping them but it's not working.
Or I'm not sure how to map them correctly as they are not defined inside ACS.
- Product type: registration_type = -name-
- Product name: registration_product = -name-
- Model/Product code: registration_productcode = xyz
- Date of purchase: registration_date = timestamp dd/mm/yyyy
