I had gravity forms set up on my site. They were tested and working. I then had the Gravity Forms to Infusionsoft plugin set up, and it was working and pushing the data to Infusionsoft correctly. I then installed the gravityforms / Authorize.net integration and added a credit card collection form as the last step of the process. Now, the credit cards are processing, but the Gravity Forms to Infusionsoft plugin is no longer posting data to Infusionsoft.
