Hi Bradley, just to clarify—are you using the latest Twilio authentication method (with

apiKey

and

apiSecret

instead of

authToken

) when making your API call to import the number? This change is required as per the latest Vapi documentation. Source: - [Vapi Changelog April 27, 2025](https://docs.vapi.ai/changelog/2025/4/27)

yes i am using those, already updated that.

Try this API request format to import your Twilio number via Vapi:

json
POST https://api.vapi.ai/phone-numbers/import
{
  "number": "+1XXXXXXXXXX",
  "twilioAccountSid": "YOUR_TWILIO_ACCOUNT_SID",
  "twilioApiKey": "YOUR_TWILIO_API_KEY",
  "twilioApiSecret": "YOUR_TWILIO_API_SECRET"
}

Ensure the phone number is in E.164 format (e.g., +1XXXXXXXXXX) and matches exactly what appears in your Twilio console. If the issue persists, double-check the number's status in Twilio and that your API credentials have the correct permissions. [See the import guide for more details.](https://docs.vapi.ai/quickstart/import-twillio) Source: - [Import number from Twilio](https://docs.vapi.ai/quickstart/import-twillio)
