With HubSpot already connected, the detail's **Status** tab includes a **Test connection** button that checks, on the spot, that the saved token is still valid against HubSpot's real API. **Requirements:** Admin role. 1. Open HubSpot's **Details** and go to the **Status** tab. 2. Press **Test connection**. **Result:** "Connection successful" if the token is still valid, or "Couldn't connect: [reason]" if the token was revoked or changed (section 8). Use it if you notice actions have stopped syncing — it's the fastest way to confirm whether the credential is the problem. The following example again uses Google Sheets — with HubSpot connected, the same "Status" tab shows the "Test connection" and "Disconnect" buttons.
