# Outgoing webhooks

Outgoing webhooks let your app's customers receive its events at an
address of their own. They are built on `publishing`
([Where events travel](where-events-travel.md)): a
customer registers an address, and the public events you choose are
delivered to it, typed from the event, signed and retried.

The customers' addresses can't be listed as connections, so outgoing
webhooks get one network exception, owned by the runtime. Its guards are
fixed:

- HTTPS only;
- no private, loopback or link-local addresses, checked on the resolved
  address at every attempt;
- no redirects followed.

The exception is listed once in the network report
([The network report](connecting-in-app-jadpo.md#the-network-report)). Nothing
else in your app, a package included, can reach an address that isn't a
declared connection.

Outgoing webhooks aren't built yet ([What is built](built-in-services-built.md)).
