The PayPal Commerce Platform is currently available to approved partners. Without this approval, calling the PayPal Commerce Platform APIs results in the HTTP status code of
401 Unauthorized. If you are interested in becoming an approved partner, we invite you to complete the PayPal Partner form, and we’ll add you to our interest list for the PayPal Commerce Platform. We will be sending more communications over the next couple of months as we work through the backlog of interest and have new information to share.
