Originally created by @jamescraig-cl on GitHub (Mar 7, 2025).

Hello! I have multiple tracing projects in my workspace and need to send data via API traces to a specific project. I looked at the API documentation for creating a run and do not see any project/workspace/other options. I can add tags, which does help segment out the data, but I'd prefer to specify a tracing project. Can the API accept project names?

Hi @jamescraig-cl, You can specify a session name or session id within each run object.

def post_run(run_id, name, run_type, inputs, parent_id=None):
    """Function to post a new run to the API."""
    data = {
        "id": run_id.hex,
        "name": name,
        "run_type": run_type,
        "inputs": inputs,
        "start_time": datetime.utcnow().isoformat(),
        "session_name: "<your project name>" <---- Add this line (or session_id)
    }
   
    requests.post(
        "https://api.smith.langchain.com/runs", # Update appropriately for self-hosted installations or the EU region
        json=data,
        headers=headers
    )
