Regarding Form Data Model Prefill service of Interactive Communication Print Channel
When creating an Interactive communication letter, is it possible to use more than one form data model.
That is data for the letter comes from three different services. For example, Customer and Billing services. At present both are written as different API services. So is it possible to combine these two services and create one Form Data Model.
If so, can this only be done via backend servlets.
Please advise.
Thanks
