I am not sure how to use a Chase Bank account with OSC to process Credit Card Payments in Authorize.net Posted February 11, 2016 Hi Jesse, They had that when I signed up several years ago but when I asked them about Authorize.net they told me I could use it and it was easy set up. Did you ask them to use Authorize.net? The gateway fees are covered by Chase and I only pay Chase. Call them and talk with somone, but I'm still using Authorize.net with Chase. Ask for interchange plus pricing too. Don't do the tier system setup if you can go interchange plus pricing. I saved a lot when I switched to Chase. John, I had Authorize.net two years ago, I had to get off that service because Authorize.net has its own transaction fees that are not part of Chase Bank. Some of the transaction fees based on $6,000 orders etc etc where well over $100. Calling Authorize.net to correct these issues was hard because they do not have USA reps. All my issues where first handled via email.... took 2 weeks to hear from them. Then I called them. That was a pain also. So I canceled the service. Chase currently does not have any business with Authorize.net because of these issues the Chase business customers where having. So Chase decided to bring their program 'Orbital Paymentech' ... here is the catch. Chase Payment tech has support for all other ecomm open source platforms, but OSC is not one of them. YES there is an app created for the Orbital Paymentech for OSC, but when I asked Paymentech for my API information, Paymentech could not get that info for me. This is why I am asking if anyone is using the Orbital Paymentech API, and how did you get your info form them? @@dan-Cole How did you get your API to get your Chase Paymentech to work?
