Get Attachments REST API php - php

Question

I am really confused in how to get a mail attachment from Outlook REST API and show it as a download link. The documentation is not precise and I have multiple forums but none could help me with it.
I took an OOP approach and this is a snippet of my code getting the attachment.
//
$getMessagesUrl = self::$outlookApiUrl."/Me/messages/".$message_id."/attachments/$attachment_id";
return self::makeApiCall($access_token, $user_email, "GET", $getMessagesUrl);
///
A get a response like this:
///
{
"#odata.context": "https://outlook.office.com/api/v2.0/$metadata#Me/Messages('AAMkAGI2THVSAAA%3D')/Attachments/$entity",
"#odata.type": "#Microsoft.OutlookServices.FileAttachment",
"#odata.id": "https://outlook.office.com/api/v2.0/Users('ddfcd489-628b-40d7-b48b-57002df800e5#1717622f-1d94-4d0c-9d74-709fad664b77')/Messages('AAMkAGI2THVSAAA=')/Attachments('AAMkAGI2j4kShdM=')",
"Id": "AAMkAGI2j4kShdM=",
"LastModifiedDateTime": "2014-10-20T00:41:52Z",
"Name": "minutes.docx",
"ContentType": "application/vnd.openxmlformats-officedocument.wordprocessingml.document",
"Size": 11585,
"IsInline": false,
"ContentId": null,
"ContentLocation": null,
"ContentBytes": "UEsDBBQABgAIAAAAIQDCAAA4KQAAAAA="
}

My problem is how to get the actual URL so I can see and download the file. Any help would be appreciated.

Answer 1

I figured out how to do it. I am using PHP and the steps are below.
1st: decode ContentBytes
$name=$attachment["Name"];
$decocedData = base64_decode($attach["ContentBytes"]);
2nd: create a file with and write the decoded data in it
$myfile = fopen("files/$name","w");
fwrite($myfile,$decocedData);
fclose($myfile);
3rd: display the url as href
echo "<a href='files/$name' download>$name</a>";
