Why teams connect Cvent and Linnworks

Feed the real customer, order, and revenue records from Linnworks into Cvent 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. Linnworks holds exactly that: Processed Orders, Stock Items, Stock Levels, Locations 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 Processed Orders, Stock Items, Stock Levels, Locations in Linnworks with Sessions, Speakers, Exhibitors, Surveys in Cvent 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 Cvent 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 Cvent flow back onto the record in Linnworks.

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 Sync orders from Linnworks into an ERP or accounting system as they are processed, without CSV exports
  • 02 Keep stock levels consistent between Linnworks and external systems so multichannel listings stay aligned with sellable stock
  • 03 Sync Sessions and Speakers into a content database or agenda app so schedule and speaker changes propagate without manual re-entry.
  • 04 Read Budgets and event financials into an ERP or finance database to reconcile planned versus actual event spend.

Common sync patterns

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 Linnworks land on the matching contact or account in Cvent, so audiences are built from what customers actually bought and spent rather than from guesses.

Suppress or target existing customers

Because Linnworks knows who is already a paying customer, Cvent can exclude them from acquisition campaigns or single them out for renewal and cross-sell.

What you can sync between Cvent and Linnworks

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.

Cvent objects Linnworks objects How this pairing syncs
Surveys Survey definitions and responses; read out to a warehouse for post-event feedback analysis alongside attendance data. Shipping Services Carrier and service definitions support label and tracking data in order syncs. Surveys is specific to Cvent and Shipping Services to Linnworks — each maps to any object or custom field on the other side.
Budgets Event budget line items; read into a finance database or ERP to reconcile planned versus actual event spend. Open Orders Unshipped orders aggregated from sales channels sync into ERPs and fulfillment systems. Budgets is specific to Cvent and Open Orders to Linnworks — each maps to any object or custom field on the other side.
Events Top-level event containers created and updated through the Events endpoints; read out for reporting and written to provision events from an external system. Processed Orders Completed orders feed accounting and warehouse-based margin reporting. Events is specific to Cvent and Processed Orders to Linnworks — each maps to any object or custom field on the other side.
Contacts Account-wide people database spanning every event; synced two-way with a CRM or warehouse as the shared audience source of truth via the Create Contacts endpoint. Stock Items SKU records keep product data aligned with ERPs and PIMs. Contacts is specific to Cvent and Stock Items to Linnworks — each maps to any object or custom field on the other side.
Attendees and Registrations Per-event registrants; written in from CRM or marketing signup flows via POST /ea/attendees and read back out to a warehouse for attendance and registration-status reporting. Stock Levels Per-location quantities sync outward so channels and planning tools reflect current availability. Attendees and Registrations is specific to Cvent and Stock Levels to Linnworks — each maps to any object or custom field on the other side.
Sessions Agenda items within an event; listed or created through the API and synced so session-level attendance feeds reporting tables. Locations Warehouse and fulfillment location records scope stock data during mapping. Sessions is specific to Cvent and Locations to Linnworks — each maps to any object or custom field on the other side.

How changes propagate between Cvent and Linnworks

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.

Cvent Linnworks Sub-second propagation

DetectionCvent notifies Stacksync of record changes through webhook events. Per-event webhooks push attendee, registration, session, and speaker changes.

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

Linnworks Cvent Interval-based propagation

DetectionStacksync polls Linnworks for changes on an incremental schedule, reading only records changed since the previous pass. Polling on order and stock endpoints.

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

Rate-limit considerations

  • Cvent: Responses carry X-RateLimit-Limit/Remaining/Reset headers; a 429 signals either the per-second limit (retry with exponential backoff from ~2s) or the daily quota (up to 500,000 calls/day on the Premium tier, 1,000/day on Free) exhausted until midnight UTC.
  • Linnworks: Per-endpoint rate limits apply on the Linnworks API.
