Property Filter

This connector sets all specified properties on ingested events to null, effectively preventing PostHog from collecting information you do not want it to use.

It is used by teams such as WittyWorks to protect user privacy by removing unneeded geographic data.

Requirements

Using this connector requires either PostHog Cloud with the data pipeline add-on, or a self-hosted PostHog instance running version 1.30.0 or later.

Self-hosting and not running 1.30.0? Find out how to update your self-hosted PostHog deployment.

Installation

Log in to your PostHog instance
Click "Data pipeline" in the left sidebar
Search for 'Property Filter' press 'Install'
Configure the by connector by following the onscreen instructions.

It's important to note that this connector effectively removes information from PostHog events by setting properties to null. Apps on PostHog run in sequence, so it usually makes sense to place this connector at the end of a sequence.

Note: If you are filtering $ip, event.ip will also be set to null.

Does this filter properties for retrospective events?

No. The Property Filter connector will only work on events ingested after it was enabled.

Configuration
