After logging in, you'll see "API" in the top navbar — click on it.

On the API page, you'll see a "+ New API Key" button on the right side. Click it — a popup will open.

A long key will appear like: "abc123XYZ..." — select it all and copy (Ctrl+C). This key is shown only once!

Come back to Studio Print. On Step 2 (Remove Background) you'll see an API Key field at the top — paste it there (Ctrl+V). It saves automatically.
