Why teams connect Extensiv (3PL Central) and Seismic

Close the gap between front office and back office: Seismic and Extensiv (3PL Central) share customers and status in real time, in both directions.

Seismic holds the customer relationship; Extensiv (3PL Central) runs the operations and records behind the business. The two overlap wherever the same organizations and transactions matter to both, and when that overlap is bridged by re-keying or overnight batch, each side spends the day working from stale data.

Stacksync syncs Reporting Activities, Library Content, Content Versions, Users in Seismic with Receivers, Shipments, Warehouses, Inventory adjustments in Extensiv (3PL Central) field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 React to ContentManager and DSR webhook events to update a database when documents are published, versioned, or expired.
  • 02 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.
  • 03 Sync commerce or ERP orders into 3PL Central for fulfillment, and sync shipment confirmations with tracking numbers back.
  • 04 Keep item masters aligned between a merchant's ERP and the 3PL warehouse so receiving and picking use consistent SKUs.

Common sync patterns

One customer master

Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.

Where Extensiv (3PL Central) manages people and org data: keep Seismic aligned

Owners, territories, and org structure informed by Extensiv (3PL Central) stay current in Seismic.

Where Extensiv (3PL Central) handles order-to-cash: closed-won flows through

A deal won in Seismic creates or updates the customer in Extensiv (3PL Central) with clean data, so fulfillment and invoicing start without re-entry.

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

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 Seismic objects How this pairing syncs
Inventory adjustments Manual stock corrections that reconciliation syncs need to capture. Reporting Activities Content-interaction, engagement, and usage analytics extracted read-only through the ETL-oriented Reporting API v2 for a warehouse. Inventory adjustments is specific to Extensiv (3PL Central) and Reporting Activities to Seismic — 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. Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. Customers is specific to Extensiv (3PL Central) and Library Content to Seismic — 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. Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. Items is specific to Extensiv (3PL Central) and Content Versions to Seismic — each maps to any object or custom field on the other side.
Inventory On-hand and available quantities by warehouse, mirrored out to drive channel availability. Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. Inventory is specific to Extensiv (3PL Central) and Users to Seismic — each maps to any object or custom field on the other side.
Orders Outbound fulfillment orders pushed in from commerce or ERP systems. User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. Orders is specific to Extensiv (3PL Central) and User Groups to Seismic — each maps to any object or custom field on the other side.
Receivers Inbound receiving records (receipts/ASNs) that confirm stock arrival back to purchasing systems. Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. Receivers is specific to Extensiv (3PL Central) and Teamsites to Seismic — each maps to any object or custom field on the other side.

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

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) Seismic 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 Seismic through its API, with automatic retries and rate-limit backoff.

Seismic Extensiv (3PL Central) Sub-second propagation

DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.

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.
  • Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.
