Routing Conversations Based on Webhook Responses in Voice Assistants

Hi! I’m working on a voice assistant where a webhook returns a value like {"exists": true} or false, and I want to send the user down different paths based on that. I tried using If / Else inside Actions, but it doesn’t seem to support conditional routing. I also looked into using Outcomes on a Speak node, but it looks like I can’t reference a variable like {{exists}} or define logic like "if true then go to X". Is there a recommended way to route the conversation based on a webhook’s response value? Any help would be greatly appreciated!
