With Salesforce already connected, the detail's **Status** tab includes a **Test connection** button that checks, on the spot, that the saved credentials are still valid against your Salesforce org. **Requirements:** Admin role. 1. Open Salesforce's **Details** and go to the **Status** tab. 2. Press **Test connection**. **Result:** "Connection successful" if the credentials are still valid, or "Couldn't connect: [reason]" if they were revoked, expired or changed (section 8). The following example again uses Google Sheets — with Salesforce connected, the same "Status" tab shows the "Test connection" and "Disconnect" buttons.
