Sume webhook vs async polling vs sync vs subscribe: pick a mode

Sume has four communication modes: async, sync, webhook and subscribe. Webhook is best for servers, but keep the poll fallback for lost deliveries.

Sume documents four communication modes for jobs: async, sync, webhook and subscribe (read 2026-10-06 in the webhook docs). Webhook suits a server that needs a notification at a terminal state.

Which should I choose?

Use webhook for server pipelines, and keep polling in place because delivery is an optimization, never the only recovery path.

What should I do in practice?

Mix webhook and polling for resilience.

  • Webhook for backend pipelines.
  • Poll status_url for lost events.
  • See the Jobs and results page for the others.
