I created an automation in Jira, which creates a branch whenever a card is moved in Jira. This automation uses a web request to trigger the Github API.
My problem is that this branch is being created based on the fixed hash of a commit, so it is not being created updated.
Below is the Github documentation I used to put together the automation.
I need to know which Github API allows me to create a branch, always starting from its last commit.
