Preferences

Learn how notification preferences work in Knock.

Preferences enable your users to opt-out of the notifications you send using Knock.

How preferences work

A user has a PreferenceSet. A PreferenceSet is a JSON object that tells Knock which channels, categories, and/or workflows a user has opted out of receiving.

When Knock runs a workflow for a user, we evalute their PreferenceSet. A message will not send if the user has opted out of receiving it.

With Knock preferences you can power standard preference use cases, such as the topic-channel preferences grid picture below, as well as advanced use cases such as per-workflow preferences, send time preferences, and more.
