CiviCRM CiviContribute CiviMember CiviMail CiviEvent payment processor

Hello everyone,

I've been trying to sort through the various payment options and gateways. We have a need based to use Verisign/Payflow Pro as our payment gateway because some legacy software we have (iMis) will only integrate with that one option, but would also like to transition to CiviCRM, but after talking on the phone with PayPal have decided that what's currently listed as payment processor will not support Payflow Pro.
