Knock API

Other

Knock is a notification infrastructure platform focused on notification workflows and in-app notification feeds. Unlike basic transactional email APIs, Knock provides a workflow engine where you visually design multi-step notification sequences: wait steps, batch/digest steps, branch conditions, and channel delivery across email, SMS, push, Slack, and in-app feeds. Knock's in-app feed is a first-class primitive — a pre-built, real-time notification feed component (React, Angular, iOS, Android SDKs) that renders a bell icon / notification drawer, eliminating the need to build this common UI pattern. The API handles user identity, preferences, workflow triggering, and feed state management (read/unread/archived).
