57020: Authorization failed

This error appears when Twilio cannot validate the request's Authorization header on a Messaging request. Twilio API requests use HTTP Basic authentication, and Twilio recommends API keys and API key secrets for production applications.

• The request does not include an Authorization header.
• The Authorization header does not contain valid Twilio API credentials.

• Add a valid Authorization header to the request and authenticate with HTTP Basic authentication.
• Use an API key and API key secret for production requests.
• For local testing, use your Account SID and Auth Token.
