User Task Extension property update

How can I use the REST API to update a Extension property defined in my user task activity?

Hi @adat,
I don’t think that Camunda has such API. Can you may be explain, why would you need to change it? What is your use case? Can’t you use variables instead?

@sdorokhova - I have dashboard for layman user to whom the cockpit process flow is too technical. I have to change the color of the activity depending on what state it is, for whoich I want to use the extension variable value in BPMN.io aoi.
Uploading what I have in place now.

I’m afraid, you can’t change property value in runtime at all. They are just not intended to be used like this. Try to use process variable instead.
