## TL;DR

Use a personal access token with the official client rather than basic auth with an API key, which is the legacy pattern. Then add tasks one by one against the new project ID.

## Steps

1. When you create Asana projects via the API, fetch the workspace or team ID first and include it in the create call; the project wont create without one. Then add tasks one by one against the new project ID. Use a personal access token with the official client rather than basic auth with an API key, which is the legacy pattern.
