03/25/2025, 5:56 PMAre you getting any errors? What are you trying to do? Rem with N8N you have a development and production webhook so make sure you test on DEV first then you can make sure you use the PROD webhook in production when its live.

03/25/2025, 6:13 PMhow do you know the tool is called? do you see it in the VAPI logs?
AiTitus :)
03/25/2025, 6:13 PMyou need to run on development make sure the dev webhook is running on test
AiTitus :)
03/25/2025, 6:13 PMthen use your VAPI and if its a tool call it will hit
AiTitus :)
03/25/2025, 6:14 PMotherwise if you are using for transient agents etc (server url) then you need to put in the DEV one and run to see if it hits the url which it should
AiTitus :)
03/25/2025, 6:14 PMthen do you tests etc making sure DEV is running on N8N
AiTitus :)
03/25/2025, 6:14 PMonce you are happy you can switch the VAPI prod url or Tool url to the PROD webhook and you should be good to go

03/26/2025, 11:14 PM@AiTitus :) The team decides when it's the right time to push features to the weekly channel. If they think LiveKit requires more time to be on daily rather than weekly, that's why they haven't pushed yet. So I'll suggest you wait a littel more time.
