With Zoho CRM 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 Zoho's real API. **Requirements:** Admin role. 1. Open Zoho CRM's **Detail** and go to the **Status** tab. 2. Click **Test connection**. **Result:** "Connection successful" if the token is still valid, or "Couldn't connect: [reason]" if the token was revoked or the data center stopped matching (section 8). Unlike the authorization code (which expires in minutes), the token saved after connecting renews itself — you don't need to repeat section 3 unless you revoke access from your own Zoho account. The example below uses Google Sheets again — with Zoho CRM connected, the same "Status" tab shows the "Test connection" and "Disconnect" buttons.
