I'm bit new to this whole implementation of Visa API to issuer bank, need few clarification
1. For "Debit Card Inquiry" api in "DPS Card and Account Services", the request parameters has two mandatory parameters "directDebitAccountNumber" and "routingNumber". For "directDebitAccountNumber" is it referring to the customer savings account number or is it some internal account number not known to end customer and only used for interaction between bank and Visa. How different is "directDebitAccountNumber" is from "primaryAccountNumber".
2. For "Customer Rules API" in "Visa Transaction Control", after going through the docs my understanding is when a customer registers a card for VTC a document_id is generated for the that particular card. Now when different controls are configured by the customer for that particular card they are all linked to the previous generated document_id. Can there be a case when a particular card that has more than one document_id. If so what the scenario in which many document_id for a particular card is possible.

VTC: Anytime that an application calls Visa Transaction Controls (VTC) to register a card, a document will be created and VTC will respond with the document ID. If that same card is registered again, the same document ID will be returned unless the second registration is from a second application. At this time, VTC does not have a full solution for multiple applications and there is potential for conflict unless the document ID is stored by each application. During onboarding, VTC requests that a single application ID be generated in VDP to prevent multiple documents being created.

DPS: Yes, the "directDebitAccountNumber" is referring to the customer savings account number. The "primaryAccountNumber" or PAN, refers to the 16 digit card number.
