WordPress developers have long known that Gravity Forms is a powerful tool that can be used to build complex applications and workflows, but sometimes good examples can help spur great ideas.
With that in mind Steven Henty, one of our brilliant Gravity Forms developers, has published a great tutorial on leveraging the Gravity Forms API to create a custom approval workflow.
This is the second indepth tutorial that Steven has written on building applications with Gravity Forms. His first was an introductory tutorial to using Gravity Forms as a platform.
If you have any interest in building applications with Gravity Forms or are just curious as to more advanced usage, we definitely encourage you to check out both of these great tutorials!
