60436: Recipient invalid or not provided

Twilio returns this error when your Verify request does not include a valid recipient destination. Verify accepts a phone number or an email address as the destination, and phone numbers must be provided in E.164 format.

• The request did not include the recipient destination required for the verification request.
• The recipient is a phone number that is not formatted in E.164.
• The selected Verify channel and recipient type do not match, such as using the email channel without an email address.
• Your application passed unconfirmed user input, such as a mistyped phone number or email address. Confirming contact information and validating phone numbers before sending an OTP helps catch these errors earlier.

• Include the recipient destination in the request body and resend the verification request.
• For sms, call, whatsapp, sna, or auto, send the recipient as a complete E.164 phone number, such as +14155552671.
• For the email channel, send an email address as the destination and make sure your Verify email integration is configured before sending email verifications.
• Normalize and validate phone numbers before creating a verification. Use Lookup if you need help converting or screening user input before you send the OTP.
