Common notes on TransactionId:
The TransactionId is completely different than the TransId:
the TransId is provided by you to identify a request sent by you to Computop Paygate
the TransactionId is provided by an external service provider (like credit card schemes / providers, PayPal, PPRO, ...)
Credit cards:
The TransactionId is a reference returned by card schemes or external CC providers to identify a credit card on their side.
with "MsgVer=2.0" (i.e. used to initiate a payment with 3-D Secure 2.x - including fallback 3-D Secure 2.x -> 3-D Secure 1.0)
the schemeReferenceID is returned instead of the TransactionId
you will use JSON-objects in combination with schemeReferenceID for recurring use cases
without "MsgVer=2.0" (i.e. do not apply for 3-D Secure 2.x)
the TransactionId is returned
you will use RTF-parameter in combination with TransactionId for recurring use cases
