Thanks for a quick reply!
Unfortunately, it's not what I was looking for.
I need credentials to login to Partners Interface
According to documentation only Authorize.Net developers team can help me
I hope you all are doing well, I join @nazik888 asking the same question.
I really need to get a set of partner login id and password to implement and test this workflow in the Sandbox Environment.
Could anyone that use OAuth in the Sandbox environment tell me how can We get the credentials to log into the Partners Interface??
I tried sending several emails, calling, via twitter and from here and no answers. It seems like Authorize.net is not interested in getting new customers anymore... or the customer service is so slow that is like it is absent.
