We are in the process of building a new website and have it staged on a new URL for testing. We have a Payments Pro account. The old site is using the API username and certificate for Direct Payment and PayPal Express.
The new site wants API username, password and signature. I've found where to request this info, but the big question is, can I request this info without messing up the store I already have running? Can they both run at the same time?
Thanks in advance.
