What is filename for SMS-sent images processed by Twilio?

When I send an SMS to my Twilio number which includes an image, there doesn't appear to be a filename associated with the image.

I'm using Twilio Studio.

Example:

  • Send an SMS text with image to my Twilio number
  • A Twilio Studio Flow pipes the {{trigger.message.MediaUrl0}} and sends an SMS text sent to my actual phone number
  • The URL is of the following format https://api.twilio.com/2010-04-01/Accounts/<long-GUID-1>/Messages/<long-GUID-2>/Media/<long-GUID-3>
  • Clicking on this URL opens a browser pointing to a translated URL https://s3-external-1.amazonaws.com/media.twiliocdn.com/<long-GUID-1>/<long-GUID-4> and showing the original image
  • But no filename.

I'm trying to access the filename so I can apply a naming convention to it. How is this accessed?

Solution

  • The URL to download the actual media is dynamically generated.
