My guess is that there actually is an error occurring—something to do with the fact that my credit card is not a real card (but a test card) and Stripe is attempting to process in production mode.
I also set up a WePay account. Neither Stripe nor WePay seem to have a way to switch to test mode. I know that Stripe can be set to test mode by using the test keys on my Stripe account, but how do I configure Infusionsoft to use those keys?
According to Support, they basically act as a pass-through for each of the different payment gateway merchants and you have to sign into Infusionsoft to check the actual error message. That’s what I understood, anyway. Nothing helpful comes through the API call.
