rollback_app
Rollback an app to a previous deployment. A new deployment will be
created to perform the rollback.
The app will be pinned to the rollback deployment preventing any new
deployments from being created, either manually or through Auto Deploy on Push webhooks.
To resume deployments, the rollback must beeither committed or reverted.
It is recommended to use the Validate App Rollback endpoint to double check if the rollback is valid and if there are any warnings.
