Feed Examples

Patch Extend is in Beta

Patch Extend is currently in beta and available for testing. We're actively refining the feature and building out comprehensive documentation. We recommend evaluating it in a test environment before deploying to production, and we welcome your feedback as we continue to improve!

Below are example Patch Extend feed definitions for a few different application scenarios.
