For the Twilio SMS channel, you can use the MediaUrl
parameter in the response to deliver an image. Let’s see an example of how to send an outbound message that includes an image and a text message.
Sample API CURL Script
curl -XPOST https://api.twilio.com/2010-04-01/Accounts/ACXXXXXXXXXXXXXXXX/Messages.json \
--data-urlencode "To=+13105555555" \
--data-urlencode "From=+12125551234" \
--data-urlencode "MediaUrl=https://demo.twilio.com/owl.png" \
--data-urlencode "Body=Hello, here is how it looks!" \
-u 'ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:your_auth_token'
