90032: Broadcast recipient's 'to' is invalid

Twilio could not process the broadcast recipient because the to value is not in a valid format. Set to to a channel and address pair in the format channel:address.

• The to value does not include the required colon separator between the channel and address
• The channel name in to is missing or misspelled
• The address portion of to is empty
• The address does not match the expected format for the selected channel
• The request sends the recipient object with an incorrectly structured or malformed to field

• Update the recipient to value to use the required channel:address format
• Verify that the channel is valid for your Notify integration, such as sms, whatsapp, facebook-messenger, or another supported channel
• Confirm that the address is valid for the selected channel, such as an E.164 phone number for sms or whatsapp
• Review your request payload before sending it and reject recipients with missing or malformed to values
• If you generate recipient objects programmatically, add validation to ensure every to value includes both a channel and an address

• Notify API overview
• E.164 formatting
• WhatsApp with Twilio
