Copying Twilio MMS Media files to my server - twilio

Question

I have an API end point set up on my server for Twilio to notify my server when an SMS/MMS is received.
Up until about 2 weeks ago, I was able to copy the media files of an MMS to my server using the PHP Copy function:
copy($sourceFile, $destinationFolder.$destinationFileName);
Where
$sourceFile = 'https://api.twilio.com/2010-04-01/Accounts/AC000000001/Messages/MM000000001/Media/ME000000001'
However, now, instead of getting the media file, I'm getting XML that describes the file:
<?xml version='1.0' encoding='UTF-8'?>
<TwilioResponse>
<Media>
<Sid/>
<AccountSid>AC000000001</AccountSid>
<ParentSid/>
<ContentType/>
<DateCreated>Thu, 04 Apr 2019 15:31:30 +0000</DateCreated>
<DateUpdated>Thu, 04 Apr 2019 15:31:30 +0000</DateUpdated>
<Uri>/2010-04-01/Accounts/AC000000001/Messages/MM000000001/Media/ME000000001</Uri>
</Media>
</TwilioResponse>
Nothing has changed in my code and I can't find any documentation suggesting that Twilio was changing how things work.
I tried changing to a curl request and I get the same result. I also tried using the Twilio PHP SDK and following this documentation: https://www.twilio.com/docs/sms/api/media-resource#default-content-type
Does anyone have some insight as to what is happening/what changed and how to get around this?

Answer 1

If you look at the "ME000000001" from
$sourceFile = 'https://api.twilio.com/2010-04-01/Accounts/AC000000001/Messages/MM000000001/Media/ME000000001'
and then at the "ME000000001" from the XML response
<Uri>/2010-04-01/Accounts/AC000000001/Messages/MM000000001/Media/ME000000001</Uri>
they are different.
In fact for a message with, let's say 3 media attachments, the XML response will look something like:
<?xml version='1.0' encoding='UTF-8'?>
<TwilioResponse>
<MediaList end="2" firstpageuri="/2010-04-01/Accounts/AC.../Messages/MM.../Media?Pag...>
<Media>
<Sid>ME...92c</Sid>
<AccountSid>AC...3e4</AccountSid>
<ParentSid>MM...e3d</ParentSid>
<ContentType>image/jpeg</ContentType>
<DateCreated>Tue, 09 Apr 2019 20:06:33 +0000</DateCreated>
<DateUpdated>Tue, 09 Apr 2019 20:06:33 +0000</DateUpdated>
<Uri>/2010-04-01/Accounts/AC...3e4/Messages/MM.../Media/ME...92c</Uri>
</Media>
<Media>
<Sid>ME...4ac</Sid>
<AccountSid>AC...3e4</AccountSid>
<ParentSid>MM...e3d</ParentSid>
<ContentType>image/jpeg</ContentType>
<DateCreated>Tue, 09 Apr 2019 20:06:33 +0000</DateCreated>
<DateUpdated>Tue, 09 Apr 2019 20:06:33 +0000</DateUpdated>
<Uri>/2010-04-01/Accounts/AC.../Messages/MM.../Media/ME...4ac</Uri>
</Media>
<Media>
<Sid>ME...048</Sid>
<AccountSid>AC...3e4</AccountSid>
<ParentSid>MM...e3d</ParentSid>
<ContentType>image/jpeg</ContentType>
<DateCreated>Tue, 09 Apr 2019 20:06:33 +0000</DateCreated>
<DateUpdated>Tue, 09 Apr 2019 20:06:33 +0000</DateUpdated>
<Uri>/2010-04-01/Accounts/AC.../Messages/MM.../Media/ME...048</Uri>
</Media>
</MediaList>
</TwilioResponse>
So, you'll find the media at the address in <Uri>...</Uri> (of course prepend with https://api.twilio.com).
Observe how the three Uris are different because they point to different media attached to the same message.
<Uri>/2010-04-01/Accounts/AC.../Messages/MM.../Media/ME...92c</Uri>
<Uri>/2010-04-01/Accounts/AC.../Messages/MM.../Media/ME...4ac</Uri>
<Uri>/2010-04-01/Accounts/AC.../Messages/MM.../Media/ME...048</Uri>
