Actions are used to define what a user can do in a task. Actions are defined in the process file (BPMN) and have authorization rules attached to them defined in the policy file (XACML) to controll who can execute them.
We have two types of actions:
Server actions
Arbitrary code that can be executed on the server as part of the process. These actions are typically used to help the user fill out the form by prefilling data, perform calculations, call external api’s etc. »
