Accessing Cisco Prime API

Hi All - sorry i'm not too experienced with API's and development, hopefully this question is OK;

I am interested in using the API in Cisco Prime Infrastructure (3.7.0). Following the built in tutorial on Prime (https://Server/webacs/api/v4/?id=tutorials ) I get to this step;

For this tutorial, the host name of my server is "my_server". So without further ado, here's our first cURL query.

curl -k "https://user:password@my_server/webacs/api/v4/data/Devices "

When i try that, this is the output i get (i added the Prime Cert to my PC Trusted Certs, i'm using windows w/ PowerShell);

PS C:\Users\> curl "https://MyUser:MyPass@ServerIP/webacs/api/v4/data/Devices"

StatusCode : 200

I believe I should get a list of Devices managed in Prime. I'm not sure why this is happening. The account I'm using for the API call has these permissions ticked;

NBI Credential

NBI Read

NBI Write

Any idea's or tips on what to try next?

Thanks !

Hi @luke.brooker1,

The cURL example uses the -k flag (probably -K, see list-of-curl-options.txt) but it appears you left this out in your call.

Hope this helps!

I got this all working, i ended up using 'Postman API platform' which created the Auth details for me, and could export for use in PowerShell.. This was what i required;

$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Authorization", "Basic <<Snip>>")
$headers.Add("Cookie", "JSESSIONID=<<Snip>>")

and then any API call just needed to be appended with;

-Method 'GET' -Headers $headers

Once i worked this bit out, everything worked fine 🙂
