This endpoint returns information about the virtual IBAN which YouLend create for each agreement. This endpoint also returns the account opening letter for the account.
For partners which perform the sweep, this endpoint needs to be called because the virtualIban/ secondaryVirtualIban describe the account to which the sweep needs to be sent in order to repay the funding.
virtualIban and secondaryVirtualIban have the same destination, the difference is that virtualIban is typically a DK IBAN and and secondaryVirtualIban is typically GB.
