Integrations
Zoho
Two-way sync with Zoho Mail, Calendar, and CRM. Multi-DC support (US, EU, IN, AU). Keep Zoho if you want to.
What's connected
| Surface | Sync direction | Notes |
|---|---|---|
| Zoho Mail | Two-way | Read, send, label. Threaded with other connected mailboxes. |
| Zoho Calendar | Two-way | Events, free/busy, conflict detection. |
| Zoho CRM | Two-way | Contacts, companies, deals, activities. |
Multi-DC
Zoho runs separate accounts.zoho domains per data center. ThorStack supports US, EU, IN, AU. The DC is detected from your account during connect; you can override if needed (rare).
CRM two-way sync
The Zoho CRM integration is a real two-way sync, not a one-shot import:
- Initial sync copies your existing CRM into ThorStack with consistent IDs.
- Live sync propagates changes in either direction within a tick.
- Conflict resolution prefers the most-recent change by default; you can configure field-level "winner" rules in Settings → Integrations → Zoho CRM → Sync rules.
If you decide later to retire Zoho CRM, the data has already been migrated, flipping the switch from "Zoho is system of record" to "ThorStack is system of record" is a setting change, not a re-import.
Mail and calendar
Zoho Mail and Calendar behave like the Google and Microsoft equivalents, unified inbox, unified calendar, conflict detection.
