Why teams connect Extensiv (3PL Central) and Iterable

Feed the real customer, order, and revenue records from Extensiv (3PL Central) into Iterable so campaigns run on who actually bought what, and let contact and consent changes flow back in real time.

Marketing runs on lists of people, but the list rarely knows which of those people are paying customers, what they ordered, or what they are worth. Extensiv (3PL Central) holds exactly that: Inventory, Orders, Receivers, Shipments that record who the customer is, what they bought, and what they owe. When the two are joined only by a periodic export, campaigns go out against stale audiences, existing customers get prospecting emails, high-value accounts look the same as cold leads, and a canceled order still counts toward a segment.

Stacksync syncs Inventory, Orders, Receivers, Shipments in Extensiv (3PL Central) with Users, Events, Campaigns, Templates in Iterable in real time, and where both sides accept writes, in both directions. Customer, order, and invoice data maps field by field onto the contacts, audiences, or accounts Iterable works with, so segmentation and personalization run on current purchase history instead of a month-old snapshot. Contact details and consent changes that originate in Iterable flow back onto the record in Extensiv (3PL Central).

The strongest bridge between the two is identity and purchase history, who the customer is and what they have bought, so that is where most of the value sits. Because the sync is field-level, each system keeps the attributes the other has no use for; only the shared records are held in agreement.

Common use cases

  • 01 Push receiving confirmations back to purchasing systems when inbound stock arrives.
  • 02 Consolidate order and shipment data across 3PL clients into a reporting database for billing and SLA tracking.
  • 03 Stream Iterable System Webhook events into a database in near real time so opens, clicks, bounces, and unsubscribes land alongside CRM contact records.
  • 04 Write list subscribe/unsubscribe changes from a CRM back into Iterable Lists so suppression and opt-in state stay current before the next send.

Common sync patterns

Where Iterable captures new people: signups become customer records

Registrations, form fills, or new subscribers in Iterable create or update the corresponding record in Extensiv (3PL Central), so the back office sees them without anyone re-keying.

Consent and contact changes travel

Email, address, or subscription-status changes stay aligned across both systems, so a customer who updates their details or opts out is respected everywhere.

Purchase history drives segmentation

Orders, invoices, and revenue totals from Extensiv (3PL Central) land on the matching contact or account in Iterable, so audiences are built from what customers actually bought and spent rather than from guesses.

What you can sync between Extensiv (3PL Central) and Iterable

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.

Extensiv (3PL Central) objects Iterable objects How this pairing syncs
Receivers Inbound receiving records (receipts/ASNs) that confirm stock arrival back to purchasing systems. Commerce / Purchases Purchase and cart activity tracked via /api/commerce/trackPurchase and /api/commerce/updateCart, feeding revenue attribution and abandoned-cart journeys. Receivers is specific to Extensiv (3PL Central) and Commerce / Purchases to Iterable — each maps to any object or custom field on the other side.
Shipments Carrier and tracking details synced back once orders ship. 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. Shipments is specific to Extensiv (3PL Central) and Export data to Iterable — each maps to any object or custom field on the other side.
Warehouses Facility records that partition inventory and order routing. 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. Warehouses is specific to Extensiv (3PL Central) and Users to Iterable — each maps to any object or custom field on the other side.
Inventory adjustments Manual stock corrections that reconciliation syncs need to capture. 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}. Inventory adjustments is specific to Extensiv (3PL Central) and Events to Iterable — each maps to any object or custom field on the other side.
Customers The 3PL's clients; nearly every other record is scoped to one, so syncs carry customer context on each call. 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. Customers is specific to Extensiv (3PL Central) and Campaigns to Iterable — each maps to any object or custom field on the other side.
Items SKU masters kept aligned between the merchant's systems and the warehouse. 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. Items is specific to Extensiv (3PL Central) and Templates to Iterable — each maps to any object or custom field on the other side.

How changes propagate between Extensiv (3PL Central) and Iterable

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.

Extensiv (3PL Central) Iterable Sub-second propagation

DetectionExtensiv (3PL Central) notifies Stacksync of record changes through webhook events. Webhook events for order, receipt, item, and inventory changes, with polling on modified-date filters as a fallback.

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

Iterable Extensiv (3PL Central) 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 Extensiv (3PL Central) through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Extensiv (3PL Central): Subject to the platform's API rate limits; batch endpoints reduce call volume for order and inventory syncs.
  • 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.
