I integrated twilio by following this tutorial https://v12.botpress.com/messaging-channels/broker-integrations/twilio I already built the corresponding webhook with public https call using ngrok and I configured it in twilio but the chatbot is not responding while I tested with what's app. I investigated more and I wanted to test the webhook with postman but I got 401 error with unauthorized message, is there an authentication should be done before using the webhook?

That is for the V12. If you are using the V12 feel free to ask in #1112845893931110402

no one responding from yesterday 😦

The V12 is not being maintained or updated any more. Botpress is focusing on new updates for the Cloud version. There are a few Botpress employees that still help in that channel, but they don't prioritize it over current projects 🙂
