Gift Certificate setup

I followed the V4 guide to setup gift certificates but it’s slightly different in V5.

anyone have experience setting it up?

Maybe try actually asking about the problem/difference.
What are you struggling on?

It works fine on V5. But the issue you mentioned before about not being able to save account document types was a bug in 5.2.2/3, it is now fixed. Update to latest release (5.2.12 or 5.2.13 beta) and you should be able to follow the tutorial without issue.
