14109: TwiML Reply message limit exceeded

This warning occurs when your application returns more than 10 TwiML reply messages for a single incoming message. Twilio supports multiple <Message> verbs in a Messaging TwiML response, but the limit for replies to one inbound message is 10.

• Your application logic created a runaway loop or another repeated execution path that generated more than 10 reply messages for the same incoming message.
• Your webhook intentionally returned more than 10 <Message> replies for one inbound message.

• Limit your TwiML response so each incoming message produces 10 or fewer <Message> replies.
• If you need to send more than 10 outbound messages for one inbound message, create the additional messages with the Messages resource instead of returning them as TwiML replies.
• Review your webhook and application flow for loops or repeated execution so the same inbound message does not trigger the reply logic multiple times.
