Hello Everyone, 

I would like to add a team / user on Workfront project (i.e. people section of the WF project).
I tried the beloew 

 

  1. Custom API module 
    URI : prjusr
    Method : Post 
    Query String : ProjectID & UserID

    Error : Invalid Json at line 1 (If the parameters are passed in the Body section)
    -OR-
    null objCode (when the parameters were passed as Query Strings)
     
  2. Create Record
    Record type : Project User
    Passed both fields : Project ID & User ID 

    Error : PRTU is not a top level object

Hi ​@harishdev,  It’s a bit of a tricky api call.   but,  Here’s my call:

 

In the URL field (without quotes) add “proj/IDGOESHERE?updates=”

 

Body: {"projectUsers":[{"userID":"IDGOESHERE"},{"userID":"IDGOESHERE"}]}

    ​@harishdev  Use the Project User API (prjusr). Don’t pass an objCode—POST projectID and userID to the prjusr endpoint with proper JSON or form-encoded body and include your apiKey or sessionID.

     

    Example (JSON, curl) curl -X POST "https://<company>.my.workfront.com/attask/api/v9.0/prjusr?apiKey=<APIKEY>"
    -H "Content-Type: application/json"
    -d '{"projectID":"<PROJECT_ID>","userID":"<USER_ID>"}'
     

    Example (form-encoded, curl) curl -X POST "https://<company>.my.workfront.com/attask/api/v9.0/prjusr?apiKey=<APIKEY>"
    -H "Content-Type: application/x-www-form-urlencoded"
    --data "projectID=<PROJECT_ID>&userID=<USER_ID>"

     

    Notes / common fixes:

    • Error “Invalid JSON at line 1” means your request body wasn’t valid JSON; use a JSON object or use form-encoded data and set the correct Content-Type header.
    • Error “null objCode / PRTU is not a top level object” means you supplied the wrong object code or payload structure. The endpoint is prjusr (no objCode needed). Don’t set objCode in the body.
    • Make sure the user ID and project ID exist and you have permission to add team members.
    • If you need to set role or billing, include extra fields (roleID or isPM etc.) — check your Workfront schema for allowed prjusr fields.
    • If using a connector (Zapier/Workato/etc.), pick the “Project User” object or set the object code to prjusr (not PRTU).
