Why teams connect Iterable and Nutshell

Keep the people you sell to and the people you market to in one shared view: Nutshell and Iterable sync contacts, accounts, and engagement in real time, in both directions.

Nutshell owns the customer relationship and the pipeline; Iterable runs the campaigns, audiences, and outreach that fill it. The two overlap on the same people and companies — a lead in one system is a subscriber, a segment member, an event registrant, or an ad audience in the other. When that overlap is bridged by CSV exports or a nightly job, sales works from lists that no longer match reality and marketing keeps targeting people whose status has already moved on.

Stacksync syncs Leads, People, Companies, Activities in Nutshell with Catalogs, Commerce / Purchases, Export data, Users in Iterable field by field, in real time, and in both directions. You decide which system owns which fields — Nutshell can own account and opportunity status while Iterable owns engagement and campaign membership — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Mirror tasks and activities into ops tools for cross-team visibility.
  • 02 Sync Nutshell leads into a warehouse or Postgres so small B2B teams can report on pipeline without exports.
  • 03 Track product and revenue Events (custom events, trackPurchase, updateCart) into Iterable from an app or database so journeys trigger on live behavior.
  • 04 Export Iterable engagement data (emailSend, emailOpen, emailClick, emailBounce, purchase) into a warehouse for deliverability and campaign reporting.

Common sync patterns

New and updated people stay in step

When a contact or lead is created or edited in either system, the matching record appears or updates in the other, so campaigns reach real people and reps see who is already being marketed to.

Where Iterable captures engagement: activity lands on the record

Opens, clicks, form fills, event attendance, or ad responses recorded in Iterable post back to the contact or account in Nutshell, so reps see interest before they reach out.

Lead and lifecycle status agree

Status, stage, or score set in one system updates the matching record in the other, so a lead marketing is still nurturing is not worked as sales-ready, and a closed account stops receiving prospecting.

What you can sync between Iterable 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.

Iterable objects Nutshell objects How this pairing syncs
Users User profiles keyed by email or userId with custom data fields; upserted via POST /api/users/update, read via GET /api/users/{email} or getByUserId, bulk-written via /api/users/bulkUpdate (up to 1000 users per call), and deleted or GDPR-forgotten. Users Rep records used to resolve ownership when syncing assignments Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping.
Commerce / Purchases Purchase and cart activity tracked via /api/commerce/trackPurchase and /api/commerce/updateCart, feeding revenue attribution and abandoned-cart journeys. People Individual contacts, kept consistent with marketing and outreach tools Commerce / Purchases is specific to Iterable and People to Nutshell — each maps to any object or custom field on the other side.
Export data Historical user and event records pulled through the Export API (/api/export/data.json, data.csv, and userEvents) across data types like emailSend, emailOpen, emailClick, emailBounce, purchase, and customEvent. Companies Account records that group people and leads for account-level syncs Export data is specific to Iterable and Companies to Nutshell — each maps to any object or custom field on the other side.
Events Custom and system events tracked via /api/events/track and /api/events/trackBulk (up to 1000 events per call); a single user's event history is read via GET /api/events/{email}. Activities Logged calls, meetings, and emails used for engagement reporting Events is specific to Iterable and Activities to Nutshell — each maps to any object or custom field on the other side.
Campaigns Email, SMS, push, and in-app sends; metadata and metrics read via GET /api/campaigns and /api/campaigns/metrics, created and sent via /api/campaigns/create and /api/campaigns/trigger. Tasks Rep to-dos mirrored into external work-management or reporting systems Campaigns is specific to Iterable and Tasks to Nutshell — each maps to any object or custom field on the other side.
Templates Reusable email/SMS/push/in-app message templates with handlebars fields; read via /api/templates and per-channel get endpoints, written via /api/templates/email/upsert and the other channel upserts. Notes Free-text history attached to leads and contacts, replicated for a full timeline Templates is specific to Iterable and Notes to Nutshell — each maps to any object or custom field on the other side.

How changes propagate between Iterable and Nutshell

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Iterable Nutshell Sub-second propagation

DetectionIterable notifies Stacksync of record changes through webhook events. System Webhooks push email/SMS/push/in-app and custom events (send, open, click, bounce, complaint, unsubscribe) as JSON POSTs in near real time.

DeliveryEach detected change is written to Nutshell through its API, with automatic retries and rate-limit backoff.

Nutshell Iterable Sub-second propagation

DetectionNutshell notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, with polling as fallback.

DeliveryEach detected change is written to Iterable through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Iterable: Limits are per endpoint and per project/key; exceeding one returns HTTP 429, so exponential backoff is advised. Event tracking allows far higher volume than metadata endpoints like campaigns/templates, and the Export API is throttled more tightly. Since Nov 10, 2025, passing the key in the query string or body is rate-limited more strictly than the Api-Key header.
  • Nutshell: Subject to the platform's API rate limits.

How the Iterable and Nutshell connectors work

Iterable

Integration surface
Iterable REST API (JSON over HTTPS): Users, Events, Campaigns, Templates, Lists, Catalogs, and Commerce endpoints, plus a bulk Export API for historical data
Authentication
API key sent in the Api-Key HTTP header (also accepted as Api_Key; the name is case-insensitive). Keys are scoped by type - Server-side, JavaScript (Web SDK), or Mobile - with optional JWT-enabled keys. US projects use api.iterable.com; EU projects use api.eu.iterable.com.
Change detection
System Webhooks push email/SMS/push/in-app and custom events (send, open, click, bounce, complaint, unsubscribe) as JSON POSTs in near real time; historical backfill and incremental catch-up run through the Export API over a date range.
