I'm working with UPS's API's to create a shipping label, the problem is UPS's servers are slow so I want to breakup my queries using separate pages to avoid the user clicking submit multiple times while all the API's are being called.
Here's the rundown:
Page 1: Contact Info
gform_validation is called to validate the address (1 sec)
gform_post_paging is called to calculate the fastest/cheapest way to ship the package to us. (3 sec)
Page 2: More Information & Hidden Field w/ bestShippingMethod.
Page 3: UPS Label (generated using bestShippingMethod)
My problem is that I don't know how to pass this information to the final page. I was thinking I could pass it as a hidden field, but I don't see how to do this.
