We’ve added a new API endpoint that lets you fetch all Lists in your Courier account. This makes it easier to programmatically manage and inspect your Lists, keep external systems in sync, and build tooling or workflows that rely on up-to-date audience data. Whether you’re automating list management or powering internal dashboards, this endpoint gives you better visibility and control.
