Database webhooks

Database Webhooks send HTTP requests after INSERT, UPDATE, or DELETE events on a table. They use asynchronous pg_net calls, so long network requests do not block database changes for long.

Syntax

In-depth API docs are only for subscribers: parameters, examples, common mistakes and interview practice.
