Task inputs can be provided in multiple ways. This is configured in the workflow definition when a task is participating in the workflow.
Inputs referred from Workflow inputs
When we start a workflow, we can provide inputs to the workflow in a json format. For example:
These values can be referred as inputs into your task using the following expression:
In this example, the tasks will receive the following inputs after they are evaluated:
Inputs referred from other Task outputs
Similar to how we can refer to workflow inputs, we can also refer to an output field that was generated by a task that executed before.
Let's assume a task with the task reference name
previousTaskReference executed and produced the following output:
We can refer to these as the new task's input by using the following expression:
The expression format is based on Json Path and you can construct complex input params based on the syntax.
Hard coded inputs
Task inputs can also be hard coded in the workflow definitions. This is useful when you have a re-usable task which has configurable options that can be applied in different workflow contexts.
