Payflow dotNET - Adding additonal data parameters

[Yellowstreak]

I am using Payflow_dotNET.dll in my VB.NET web application to manage payments.  This is working fine.  Our client is an airline and has requested that we include the Airline Passenger Data Parameters detailed here in the payflow documentation:

https://developer.paypal.com/docs/classic/payflow/integration-guide/?mark=airline#processors-requiri...https://developer.paypal.com/docs/classic/payflow/integration-guide/?mark=airline#processors-requiri...

I can't see anything in the PayFlow_DotNet object model to facilitate passing this data with the transaction.  Is this possible?  If so, please can someone explain how I can do it?

Thanks,

Col.

After further investigation, it looks like I need to use the Transaction.AddToExtendData method.  I can add the name/value pairs I need via the ExtendData object and this method.

Can anyone confirm I'm on the right track?
