I’m trying to override the `scm_branch` used by a Job Template that is launched via a GitHub webhook.

I’ve already enabled **Allow Branch Override** and **Update Revision on Launch** on both the Project and the Job Template. The webhook payload includes the branch name, so I tried setting this on the `extra_vars` of the job template:

```yaml
scm_branch: "{{ awx_webhook_payload.pull_request.head.ref }}"

```

However, this doesn’t work. I also understand that `scm_branch` is normally set internally by the API, but I wanted to see if it could be overridden dynamically.

Has anyone successfully overridden the branch for a webhook-launched job? Is there a recommended pattern or workaround for this scenario?
