In this blog, you will see how to get all Yammer messages in a specific thread using PowerShell.

Prerequisites

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

  3. $threadID="1138117349"
  4. $headers = @{ Authorization=("Bearer " + $developerToken) }
  6. Function GetMessages($pageNo)
  7. {
  8. #page parameter- Programmatically paginate through the messages in the network.
  9. $uri="https://www.yammer.com/api/v1/messages/in_thread/" + $threadID +".json?page=" + $pageNo
  11. # Invoke Web Request
  12. $webRequest = Invoke-WebRequest –Uri $uri –Method Get -Headers $headers
  14. # Check whether the status code is 200
  15. if ($webRequest.StatusCode -eq 200) {
  17. # Converts a JSON-formatted string to a custom object or a hash table.
  18. $results = $webRequest.Content | ConvertFrom-Json
  20. # Loop through all the messages
  21. $results.messages | ForEach-Object {
  22. $message = $_
  23. # Display all the messages
  24. Write-Host -ForegroundColor Green $message.id ": body - plain: " $message.body.plain
  25. }
  27. # Check if there are more items available
  28. if($results.more_available)
  29. {
  30. GetMessages($pageNo+1)
  31. }
  32. }
  33. else {
  34. Write-Host -ForegroundColor Yellow "An error has occurred: " + $webRequest.StatusCode + " Description " + $webRequest.Status
  35. }
  36. }
  38. # Call the function
  39. GetMessages(1)
