Update assistant dynamic variables from webhook tool responses
24, Mar 2026
Webhook tools can now write values directly into an assistant's dynamic variables. This lets you route tool output into prompts, actions, and insights without extra middleware or post-processing.
What's new
Dynamic variable assignment: Map response fields to variables using response paths.
Response path mapping: Extract values like current.precipitation from JSON responses.
Instruction injection: Use updated variables in assistant instructions at runtime.
