As you can expect, not all CSML components work well with a SMS chatbot, as there is no support for any visual component or buttons. However you can use all of the following standard components:
Text
Question (buttons will be added in a new line under the question's title)
Image
Other components will be automatically reduced to simple text components.
Each call made to CSML Studio will have a number of metadata, based on what information is provided by Twilio. An example _metadata object would look like this:
To get started, you will need to create a Twilio account and purchase a phone number in the country of your choice. Twilio has a documentation on this topic. The only point of attention is that you must make sure that the number you purchase has Messaging capabilities. Please keep in mind that depending on your country of origin, the requirements may differ, and Twilio may ask you for business verification. Keep track of this phone number (including the country code) as you are going to need to add it later to CSML Studio!
To configure the webhook, you can either use a TwiML app, or directly set a webhook in the messaging configuration panel. Either way, you will need to set the HTTP POST webhook to https://clients.csml.dev/v1/twilio/sms/request, for example like so:
The last step is to provide CSML Studio with means to make sure that the requests that are sent to the Twilio Voice endpoint are indeed coming from Twilio. To do so, visit your Twilio Project Settings and copy your Account SID and Auth Token, found under API Credentials:
To setup your Twilio SMS channel in CSML Studio, you will simply need to visit the Channels section and create a new Twilio SMS channel. Then simply fill the required fields with the information you gathered earlier.
Once you click on Submit, your bot is ready to use!
