Why teams connect InterSystems IRIS and Nutshell

Treat Nutshell like part of your database: its records live in InterSystems IRIS as real tables, and writes in either place sync to the other in seconds.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in InterSystems IRIS, where it can be queried and joined like everything else.

Stacksync mirrors Notes, Products, Tags, Users from Nutshell into Globals, Namespaces, Stored Procedures, Tables in InterSystems IRIS with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Nutshell with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • Push closed-won leads to accounting software to trigger invoicing automatically.
  • Keep People and Companies consistent between Nutshell and email marketing or outreach tools.
  • Sync operational tables in IRIS bi-directionally with a CRM so business teams work on IRIS-backed data without SQL access
  • Consolidate IRIS data with other databases in an analytics warehouse for cross-system reporting

Product events onto CRM records

Signup, usage, or lifecycle changes written to InterSystems IRIS sync onto the matching records in Nutshell, giving go-to-market teams live product context.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Nutshell API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Nutshell arrive as row changes in InterSystems IRIS, ready to drive jobs and notifications.

What you can sync between InterSystems IRIS and Nutshell

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

InterSystems IRIS objects Nutshell objects
Schemas Schema organization scopes which tables a sync connection can see. People Individual contacts, kept consistent with marketing and outreach tools
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. Companies Account records that group people and leads for account-level syncs
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. Activities Logged calls, meetings, and emails used for engagement reporting
Namespaces Namespaces partition databases and determine the connection context for integrations. Tasks Rep to-dos mirrored into external work-management or reporting systems
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Notes Free-text history attached to leads and contacts, replicated for a full timeline
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Products Line items attached to leads, used to sync sold products into billing
