Hello, it's not possible at this time, what would the use case be?

I want automatic deployments triggered on branch deploy. This is no longer possible due to the recent deployment approval feature, without inviting every collaborator to the Railway project (which is not feasible in out situation). I'm hoping to circumvent this by approving deployments with a script, e.g. a Github action using Railway CLI to approve any pending deployment requests. (Ideally I'd like to disable the deployment approval feature altogether, but I understand there are no current plans for allowing this)

Yep you are right, there are no current plans to allow users to disable this security feature, and similarly there are no current plans to allow it to be circumvented in such a way.

Okay. Does deployment with railway up require approval? Thanks

It does not, but it should be made to require approval, good catch!
