Yup. The way I do it, through the back end webhook, first step is create a new DB(message in my case), then add it to the lead that those messages belongs to. The way I find it is, when initially we create a conversation with that receivers phone #, we add the Twilio SID CH to it, so that allows us to search the DB later on. Then to convert the twilio text to url, we use their chatservicegetmediaurl endpoint. I hope that makes sense.
