Hi there,
I am able to get the groups fine. But get 400 error when I try to suspend a user using the following:

$token = "***********************"
$url = "https://www.yammer.com/api/v1/users/357099000000.json"
$headers = @{ "Authorization" = "Bearer "+$token }

Invoke-WebRequest -Uri $url -Method Delete -Headers $Headers

Would you be able to provide advise on why this is?

Thanks in advance

Hi, there are some more guides for Yammer API here:

Getting started with Yammer REST API and PowerShell
https://techlabs.blog/categories/office-365/getting-started-with-yammer-rest-api-and-powershell

Take a look at "Delete Yammer users with REST API PowerShell" it has step by step instructions and some info about the "remote server returned an error 400 Bad Request" error. You'll need to become a member to access the guide

Hope that helps!
