Why teams connect Adyen and Cvent

Put revenue reality behind every campaign: Adyen and Cvent share the same customers, contacts, and billing status in real time, in both directions.

Adyen records the money — who pays, how much, and whether they are current; Cvent decides who hears from the business and what they hear. The two overlap wherever the same customers and contacts matter to both, and when that overlap is bridged by CSV exports or an overnight batch, campaigns target on stale billing data and finance works from lists marketing has already changed underneath it.

Stacksync syncs Merchant Accounts, Stores, Users and API Credentials, Webhook Configurations in Adyen with Events, Contacts, Attendees and Registrations, Sessions in Cvent field by field, in real time, and in both directions. You decide which system owns which fields — finance keeps the revenue and payment truth, marketing keeps consent and engagement — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Trigger a capture, refund, or cancel on an Adyen payment when an order's state changes in a CRM, OMS, or ERP, and write the returned pspReference and status back onto the record.
  • 02 Create Adyen Payment Links from an invoicing or billing system and sync each link's paid or expired status back so accounts receivable sees payment without opening the Customer Area.
  • 03 Write Attendees and Registrations into Cvent from external marketing signup flows, then read attendance status back into a warehouse.
  • 04 Sync Sessions and Speakers into a content database or agenda app so schedule and speaker changes propagate without manual re-entry.

Common sync patterns

Revenue and billing signals reach the audience

Plan tier, spend, or payment status from Adyen lands on the matching record in Cvent, so segments and targeting reflect who actually pays and how much.

One customer and contact list

Where both systems keep customer or contact records, an edit on either side propagates to the other, ending dual maintenance and the drift it creates.

Where Cvent captures new people: clean records flow to finance

Registrants, form fills, or leads created in Cvent create or update the matching customer or contact in Adyen, so billing and reporting start from accurate details without re-entry.

What you can sync between Adyen and Cvent

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.

Adyen objects Cvent objects How this pairing syncs
Payments Checkout API payment requests and results (/payments); created to authorize a card, wallet, or local payment, and retrieved by pspReference. Final state arrives asynchronously via the AUTHORISATION webhook. 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. Payments is specific to Adyen and Events to Cvent — each maps to any object or custom field on the other side.
Modifications (Captures, Refunds, Cancels) Actions on an authorized payment via /payments/{pspReference}/captures, /refunds, and /cancels; written to settle, return, or void funds, with results confirmed by CAPTURE and REFUND webhooks. 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. Modifications (Captures, Refunds, Cancels) is specific to Adyen and Contacts to Cvent — each maps to any object or custom field on the other side.
Payment Links Hosted payment link objects created through /paymentLinks; created, retrieved, and expired, with paid or expired status reported back through webhooks for accounts-receivable sync. 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. Payment Links is specific to Adyen and Attendees and Registrations to Cvent — each maps to any object or custom field on the other side.
Merchant Accounts Company and merchant account entities in the Management API; read and updated to keep account configuration, payment-method settings, and capabilities aligned with internal systems. Sessions Agenda items within an event; listed or created through the API and synced so session-level attendance feeds reporting tables. Merchant Accounts is specific to Adyen and Sessions to Cvent — each maps to any object or custom field on the other side.
Stores Physical and online store entities under a merchant account (Management API); full CRUD, so new locations and their payment-method configuration can be provisioned from an internal admin source. Speakers Speaker records tied to an event; synced two-way with a speaker database or CMS, with an updatedDate on each record for incremental pulls. Stores is specific to Adyen and Speakers to Cvent — each maps to any object or custom field on the other side.
Users and API Credentials Customer Area users and API-credential objects managed via the Management API; created, updated, and deprovisioned to keep Adyen access aligned with an IdP or HR source. Exhibitors Exhibitor and sponsor records; synced to a CRM or database to track booth, sponsorship, and lead-capture data per event. Users and API Credentials is specific to Adyen and Exhibitors to Cvent — each maps to any object or custom field on the other side.

How changes propagate between Adyen and Cvent

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.

Adyen Cvent Sub-second propagation

DetectionAdyen notifies Stacksync of record changes through webhook events. Standard webhooks for payment events (AUTHORISATION, CAPTURE, REFUND, CHARGEBACK, and more) plus Management, Balance Platform, and report webhooks.

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

Cvent Adyen 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 Adyen through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Adyen: Adyen does not publish fixed numeric rate limits; excessive requests return HTTP 429, and the Management API reports 'too many requests' in the error detail. Adyen recommends exponential backoff, and no rate-limit response headers are documented.
  • 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.
