Hi I am using authorize.net integration in test mode and using SIM method. The payment process is working fine. But I could not able to capture return values from the gateway. After successful payment I need to capture the return values from the gateway and based on that need to update the table. For example if payment process is succeeded the date of expiration for a subscription process has to be extended. Can any one suggest whether this is possible in test mode? If it is how can I do that? Thanks in advance. Shanthini.G
