How to download attachments from test run evidence?

[Vignesh Sundar]

Hi, I am trying to download the attachments from test run evidence using python script. But I am unable to download it. 

I am using the rest api suggested by the xray cloud documents. 

https://docs.getxray.app/display/XRAYCLOUD/Attachments+-+REST

Here is the API I used, https://xray.cloud.xpand-it.com/api/v1/attachments/{attachmentId}

But that is always through response code 404. 

TestRun results are shown in different link like execution page.

Here is my attachment link,

https://xray.cloud.xpand-it.com/api/internal/attachments/{attachmentId}

Can anyone please help me to download the attachments from above API
