I am creating a Twilio Autopilot program that works on the SMS channel. Currently, I set up the sms channel using the messaging URL and webhooks according to the instructions in the SMS setup section here: https://www.twilio.com/docs/autopilot/guides/how-to-build-a-chatbot. This works, but I am trying to find a way to retrieve the phone number from the incoming SMS to try and match it to a user to provide context to the bot ahead of time. Is there any way to accomplish this? I am coding this in Python but any advice would be appreciated regardless of language.
