Hi everyone;  
I have a process with 3 user tasks.  
My question is? Where in flowable I can set the initial process variables??

Where I can set task variables in each task?  
And what about saving task variables values back into process variables?

Thank you !!

Hi,

You can start a process instance with an initial payload. For example using the REST API.  
Or you could use `start form`.

> **[REST API · Flowable Open Source Documentation](https://flowable.com/open-source/docs/bpmn/ch15-REST/#start-a-process-instance)**

Regarding the task variables. Is using a `form` with a `user task` what you’re looking for?
