I am trying to use Vapi with Inworld for voice synthesis but the integration doesn't seem to work. I am 100% certain the key I am putting in has access to the correct workspace and assets because using the same API key for any call in a local script gives me expected behavior but Vapi is unable to use the key at all. I am pretty sure the reason is because Inworld expects the authirization header to be Authorization: Basic ${Api key} and that Vapi is not making the request in that format probably.

Yeah this looks like an auth format mismatch, Vapi likely sends Bearer while Inworld expects Basic, so the request gets rejected. Best fix is using a small proxy or middleware to rewrite the Authorization header. I’ve handled similar issues and can help you get it working end-to-end. Are you calling Inworld directly from Vapi or through a custom layer? @✪ Lol_Nuggets | skinbaron.de

my company is planning to do a marketing campaign using ai voice agents and i was evaluating vendors so i havent set anything up yet and was just window shopping options for ai voice support agents. all this to say that i havent really looked in depth into vapi and only used the vapi.ai website and skimmed the docs so if you could help me out that would be great

Got you, since you’re still just exploring, the key thing is to first get clear on your use case (outbound campaigns vs inbound support) because that really shapes everything. With Vapi, you may not even need Inworld unless you’re after very specific voice or character behavior. I’d suggest starting simple: map out the call flow, choose your voice + LLM stack, then only add extras if needed. Happy to help you figure this out properly and even handle the implementation with you so you don’t waste time guessing. If you’re open, we can chat privately, what kind of campaign are you looking to run? @✪ Lol_Nuggets | skinbaron.de
