Hi,

My role is an operator and I'm trying below SCOM login api using postman and i'm getting 401 error. I have followed their official documentation.

Request is like below :

POST /OperationsManager/authenticate HTTP/1.1
Host: hostname
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: token

{"credentials":"EncodedString(Network:domain\username:password)"}

And also i tried some get calls using browser and those are working.
Someone please assist. Thanks in advance!

Hi @UdeshChathurangaSendanayake-2967,

I wrote a quickstart blog post about SCOM REST API, I suggest you have a look at my examples there:

https://thesystemcenterblog.com/2020/07/09/quick-start-scom-rest-api/

My examples use PowerShell which is a modern but also a great way if you want to start automating.

(If the reply was helpful please don't forget to upvote or accept as answer, thank you)

Best regards,

Hi @LeonLaude ,

I have tried your first example to get all new alerts.
Still i'm getting below error.
{"errorMessage":"The user credentials are invalid or user does not have permissions to access the application.}

changes i have made :
$BodyRaw = "AuthenticationMode:domain\username:password" and Host

Your account does not have sufficient permissions, try first with Administrator rights.

Thank you for your quick responses.
My role is operator and do you know what is the suitable user role to achieve this? (According to POLP).

I followed below documentation,.
