How can billable hours in Tempo worklog be set to zero programmatically?

[Nadine Schuett]

Hello Atlassian Community 

We use Tempo for time-tracking in a DC environment and got the requirement to set the billable hours field to zero for each worklog on issues with a specific component. It does not really matter whether that happens each time work is logged or scheduled at the end of the month. 

I would like to use automation but, apparently, the billable field cannot be set by simply editing the issue. I saw that the field can be changed by sending web requests and I could struggle my way through that ;-) but was wondering whether someone has already had a similar challenge and might share a solution we can adopt. 

Many thanks and happy Friday!
