How to get the current issue workflow transition by name

[serge calderara]

Dear all,

I am actually investigating on the way to go for the following steps

1. From the current Issue Key
2. Get the current associated Workflow
3. From the Workflow ID fetch in point 2, get the Transisition ID by name
4. Transition the WF

Those are the steps that I try to process from my Jira cloud in script runner but could not get through

Question 1 : What is the correct way to get the Work flow from an Issue Key ?

Question 2 : How to get from the fetch WF, the transition ID of a transition name ?

Thanks for help

regards
