Hey team, I'm trying to trigger an outbound call using the new POST https://api.vapi.ai/call endpoint. I have my assistantId, phoneNumberId, and request body correct. The only issue I'm getting is authentication. When I use my Private Key (UUID format) in the Authorization header, I get: "failed to extract key" Can you provide the exact required Authorization header format for the new API? Do I need: Authorization: Bearer Authorization: api-key Authorization: X-API-Key: or another header name or format? Just want to confirm the correct header and prefix for the new Vapi key system.

Hi there, Thank you for your message. Our team is currently out of the office. We operate Monday through Friday, from 9:00 AM to 8:00 PM Pacific Standard Time (PST).

The exact Authorization header format you need for the Vapi API is:

http
Authorization: Bearer <your-api-key>

Replace

<your-api-key>

with your actual API key (not a UUID private key). This format is shown in the official documentation and is required for authentication with the

POST https://api.vapi.ai/call

endpoint. For reference, see the [Vapi API documentation](https://docs.vapi.ai/api-reference/calls/call-controller-find-all-paginated). Source: - [Vapi API Reference: Call Controller Find All Paginated](https://docs.vapi.ai/api-reference/calls/call-controller-find-all-paginated)
