CMA9 Transaction IDs
Transaction IDs are conditional in the OBIE Read/Write Specification v3.x. There are 4 options for how an ASPSP can treat this field in the API response:
ASPSPs provide a Unique, Immutable TransactionID from their core system
ASPSPs generate a Unique TransactionID from a set of Immutable fields
ASPSPs specify field(s) for TPP to generate a Unique Transaction Identifier
ASPSPs provide neither a TransactionID nor the method by which TPPs can generate one
Each of the CMA9 have been asked to confirm which of these 4 methods they will support, and this is listed below...
