Important restrictions

No free managed webhook hosting or infrastructure is included. Operate your own Go server and PostgreSQL, secure public endpoints, monitor delivery and pay for compute, networking, backups and storage. At-least-once delivery can repeat events; consumers need idempotency. Preserve MIT license notices.
