If you're not familiar with Procfiles, each line specifies a process name and command for the process. So in this default Procfile, we've specified 2 processes, web and sidekiq.
Currently, Xip uses Sidekiq for processing background jobs. It is configured to monitor 2 queues by default: xip_webhooks and xip_replies. You can specify additional queues as needed by your bot by adding -q <queue_name> to the sidekiq Procfile entry.
You can even use Sidekiq Pro and Sidekiq Enterprise if you have a license
