Summary I'm trying to use Vapi AI but keep getting "401 Unauthorized" errors even though I'm doing everything right. What I have: Private API key: 1ccbaa08-5fa8-44d9-a0fa-5d179674bcde Phone number ID: 9188c463-d168-40cf-b5aa-a7bc1e9fe6a8 Account email: ashah6@chewy.com Account has credits (not in trial mode) What happens: Every time I make an API call, I get: 401 Unauthorized "Invalid Key. Hot tip, you may be using the private key instead of the public key, or vice versa." What I've tried: Using the private key as Bearer token (as docs say) Regenerating new private keys Different phone number formats

Hi dark, To resolve the "401 Unauthorized" error you're encountering, verify the following steps: 1. **API Key Type**: Ensure you're using the correct type of API key for the endpoint you're accessing. For public endpoints, use a public key, and for endpoints that require authentication, use a private key. 2. **Correct Endpoint**: Double-check that the endpoint you are calling requires the key you are using (public or private). Each endpoint may have different authentication requirements. 3. **Dashboard Settings**: Visit the Vapi dashboard to manage and verify your API keys. Ensure they are active and correctly configured for the endpoints you are accessing. 4. **Token Inclusion**: Make sure that your API request includes the correct headers:

Authorization: Bearer your-api-key

Please ensure these steps are correctly implemented. If the error persists, consider generating a new API key from your Vapi dashboard to ensure your keys are up-to-date and troubleshoot further. For more information on server authentication, refer to the [Server Authentication](https://docs.vapi.ai/server-url/server-authentication) documentation. Also could you please send your request payload and the endpoint URL you are using?
