Downloading file from ServiceNow using Rest API

[DKS]

Hi,

First of all, I have gone through the documentation on Attachment API. I am able to get the repsonse from the API and also the Binary response(as mentioned in the doc) for the attachment. I dont quite understand how to decode this reponse and create back the original file that is there as attachment in SN.

Actually I have created a script in python and my response has characters like this - ��]�������VX�M��꥟�����2I

The same I am getting from postman as well. Please help how can I create a actual file from this.

Thanks

You shouldn't have to do any conversion of the data.  Just drop it into a file; (this is a pdi and nothing to hide feel free to try on your own with that authorization)

curl --request GET \
  --url https://dev69973.service-now.com/api/now/attachment/11f1e367db2423002a66364e9d9619bd/file \
  --header 'authorization: Basic c2xhY2s6c2xhY2s='

And it then is able to be opened.

I assume that you are suggesting to use the "download_link" instead of the binary response. For some reason, the download_link is not working in my browser as well as in python even though I supply the correct credentials when it asks for. So now my only solution is to decode/encode the response and create the file. Can you suggest me how to do that?

Thanks

I'm not using the download_link.

This is the binary download endpoint as documented here.

I provided a curl command with credientials that work, you should be able to do the same in python.

Here's what my rest editor says a working python example would be;

import http.client

conn = http.client.HTTPSConnection("dev69973.service-now.com")

payload = ""

headers = {
    'authorization': "Basic c2xhY2s6c2xhY2s="
    }

conn.request("GET", "/api/now/attachment/11f1e367db2423002a66364e9d9619bd/file", payload, headers)

res = conn.getresponse()
data = res.read()

print(data.decode("utf-8"))//yo'd have to write this to something.png
