Besides push delivery to a Worker, a queue can be configured with a pull consumer, which exposes HTTP endpoints for pulling a batch of messages and acknowledging them by lease id. That is how a process outside Cloudflare, such as a container or an existing job runner, consumes a queue.
A queue has one consumer type at a time, so switching from push to pull means removing the Worker consumer first. Pulled messages are leased rather than deleted, and a lease that is never acknowledged returns the message to the queue after a visibility timeout, so the same at-least-once and idempotency rules apply. Authentication uses an API token scoped to the queue, which must stay out of the Worker bundle and out of version control.
