How do I configure server URL at the assistant level so that we hit a certain endpoint for a specific assistant? I dont see where this is available in the UI....

In Vapi the server URL usually isn’t exposed directly in the UI at the assistant level, it’s typically set via webhook/server config through the API or advanced settings. If you need a specific endpoint per assistant, you can override it when creating or updating the assistant via API. That way each assistant can route to a different backend logic. Are you trying to route tool calls, real-time functions, or post-call webhooks? @Matt

Post-call webhooks, ah I see, i think we are figuring out the way to do this through the API as you say. I think we figured it out on the Vapi side, but we need to do a little work on our app side. Thanks

Nice, that sounds like good progress, once it’s set up on the Vapi side, the main thing is making sure your backend cleanly handles the webhook payload, validates signatures, and responds fast enough to avoid retries. A lot of issues usually come from call ID mapping or slow processing that causes silent failures. It also helps to log the raw payload at first so you can confirm the event structure before running your logic. If you’d like, I can help you review the full flow and spot any weak points. We can talk more privately and make sure it’s fully stable and production-ready. @Matt

glad you figured it out matt. let us know if you need anything from us
