Asana Portfolio Memberships API

The Asana Portfolio Memberships API allows developers to retrieve portfolio membership information. A portfolio membership represents the relationship between a user and a portfolio, including their access level such as admin, editor, or viewer. The API provides endpoints to get multiple portfolio memberships, get a specific portfolio membership, and get memberships from a specific portfolio.
