45002: Authentication Error

Twilio returned this error because the request to a protected resource did not include valid authentication credentials. This can happen when credentials are missing, incorrect, expired, or do not have permission to access the requested resource.

• The request did not include authentication credentials.
• The Account SID, API Key, API Secret, or auth token is incorrect.
• The request used expired or revoked credentials.
• The credentials are valid but do not have access to the requested Flex resource.
• The request sent the wrong authorization header format or malformed credentials.

• Confirm that your request includes authentication credentials.
• Verify that you are using the correct Account SID, API Key, API Secret, or auth token for the account and environment you want to access.
• Regenerate or rotate credentials if you suspect they have expired, been revoked, or been exposed.
• Check that the credentials you are using have permission to access the requested Flex resource.
• Review your authorization header and request formatting to make sure credentials are sent correctly.
• If you use API Keys or IAM controls, review your authentication setup and key management configuration.
