Can you integrate Nutshell with Vtiger CRM?

Yes. Stacksync provides a managed, real-time two-way integration between Nutshell and Vtiger CRM: authenticate both systems, choose the objects to sync (such as Nutshell's Companies and Activities), map fields visually, and changes propagate both ways in milliseconds — no code required.

Can the Nutshell–Vtiger CRM sync run one-way instead of two-way?

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

How do teams use the Nutshell and Vtiger CRM integration?

Common patterns for Nutshell and Vtiger CRM: Post-acquisition consolidation; Migration with a parallel run; Divisional or regional split. Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.

What should I know about the two APIs?

Nutshell: JSON-RPC API over HTTPS; a newer REST API is also offered. Authentication: HTTP Basic with account email and API key. Vtiger CRM: REST API. Authentication: HTTP Basic with username and access key. Stacksync manages authentication, retries, and rate limits on both sides.

What makes Nutshell's data model different?

Nutshell: Nutshell's most full-featured API is JSON-RPC: each call names a method such as findLeads or editLead instead of hitting resource URLs, though a newer REST API is also available. Vtiger CRM: Every entity is a module sharing a uniform CRUD interface, and the API accepts a SQL-like query syntax for filtered reads. Stacksync's field mapping accounts for these differences between Nutshell and Vtiger CRM without custom code.

Is the Nutshell–Vtiger CRM integration secure?

Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Nutshell and Vtiger CRM records are not retained after a sync operation.

Why teams connect Nutshell and Vtiger CRM

Run Nutshell and Vtiger CRM side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.

Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.

Stacksync syncs Companies, Activities, Tasks, Notes in Nutshell with Contacts, Organizations, Leads, Opportunities in Vtiger CRM in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.

Common use cases

Sync Nutshell leads into a warehouse or Postgres so small B2B teams can report on pipeline without exports.
Push closed-won leads to accounting software to trigger invoicing automatically.
Two-way contact and organization sync between Vtiger and a billing or ERP system.
Sync Cases to an external help desk or engineering tracker so support and product teams work from the same tickets.

Post-acquisition consolidation

Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.

Migration with a parallel run

When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.

Divisional or regional split

Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.
