Triggering Plan for specific PR using API

Hi,

I’ve got a question is it possible to provide PR details in request body in request to create speculative plan?

I was able to create a plan based on PR using API by reusing configuration_version from Plan automatically triggered by VCS. So I guess it should be possible to do it without already existing configuration_version, but by creating a new one (I would like to avoid uploading zip file).

Regards,
