Hello Marcelo,

Form key is still the mechanism to implement external forms in 5.21 and even in 6.0.
Keep in mind, form key is simply another piece of metadata that in this case is bound to the task.

Think of it in the same way as business data key that is bound to a process instance.

There is no built in mechanism to exploit the form key. What you have to do is create an application framework that uses REST (or the Java API if you are using server side rendering) to retrieve the task details, then take the returned form key and act on it. The form key could represent an html page, or a json structure that your frameworks understands or XML. There is no restriction on what the form key string is or represents, it is simply a piece of metadata your application understands and knows how to handle.

As an example, I wrote a simple Alpaca EZForms integration a couple of years agi that you can find here:

GitHub - gdharley/activiti-alpaca: This webapp acts as a primer to demonstrate the use of Alpaca EZforms with Activiti u…

It is dated as it was built for 1.14 and some of the REST API's I used were "legacy" API's so may no longer exist, but it should give you an idea of how to handle.

Hope this helps,

Greg
