Prerequisites:

Go to https://www.yammer.com/client_applications and register an app.

Once the app is registered, generate a developer token.

Copy the below script and paste it in a notepad. Save the file as GetUsers.ps1.

  1. # Input Parameters
  2. $developerToken = "461-yyxH31YOkutfuKoWUEmWPg"
  3. $groupID="8010451"
  4. $headers = @{ Authorization=("Bearer " + $developerToken) }
  5. $count=0;
  7. Function GetUsers($pageNo)
  8. {
  9. #page parameter- Programmatically paginate through the users in the network. 50 users will be shown per page.
  10. $uri="https://www.yammer.com/api/v1/users/in_group/" + $groupID +".json?page=" + $pageNo
  12. # Invoke Web Request
  13. $webRequest = Invoke-WebRequest –Uri $uri –Method Get -Headers $headers
  15. # Check whether the status code is 200
  16. if ($webRequest.StatusCode -eq 200) {
  18. # Converts a JSON-formatted string to a custom object or a hash table.
  19. $results = $webRequest.Content | ConvertFrom-Json
  21. $count=$count+$results.users.length
  23. # Loop through all the users
  24. $results.users | ForEach-Object {
  25. $user = $_
  26. # Display all the user details
  27. Write-Host -ForegroundColor Green "Full Name: " $user.full_name " - Email: "$user.email
  29. }
  31. # Check if there are more items available
  32. if($results.more_available)
  33. {
  34. GetUsers($pageNo+1)
  35. }
  36. else
  37. {
  38. write-host -ForegroundColor Magenta "Total number of users in this group: " $count
  39. }
  40. }
  41. else {
  42. Write-Host -ForegroundColor Yellow "An error has occurred: " + $webRequest.StatusCode + " Description " + $webRequest.Status
  43. }
  44. }
  46. # Call the function
  47. GetUsers(1)
