Event Tracking FAQ
If you would like to take advantage of Protocols Tracking Plan features, such as validation, you can add your custom events to your Protocols Tracking Plan. It won't impact Chord's tracking as long as you don't alter existing events.
You can customize Segment events from the Chord SDK with Segment middleware. This strategy allows you to intercept events after they're sent by the SDK and add properties. We don't support changing existing properties, because Chord models the data received in events, but this is a good strategy for adding additional properties to existing events.
When you use the Chord SDK in your website code, it sends events to Segment with Segment's Analytics.js library. Internally, the Chord SDK uses a Typewriter client generated from Chord's Protocols Tracking Plan. The Chord OMS sends events to Segment with Segment's Ruby library.
