Why teams connect Acumatica and Adyen

Keep Adyen and Acumatica agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.

A dedicated finance tool and an ERP end up side by side for practical reasons: a subsidiary runs lighter software than headquarters, billing runs in a specialist system while the enterprise system holds the wider view, or the company is mid-migration and both are live. Whatever the split, the two systems describe overlapping customers and transactions, and that overlap drifts without a live connection.

Stacksync syncs Merchant Accounts, Stores, Users and API Credentials, Webhook Configurations in Adyen with Customers, Vendors, Sales Orders, Invoices in Acumatica in real time and in both directions. You decide which system wins on which field, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • 01 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.
  • 02 Provision Stores, Users, and API credentials through the Management API from an internal admin app or IdP so new locations and staff get the right Adyen access automatically.
  • 03 Two-way sync of customers, orders, and invoices between Acumatica and a CRM so sales sees ERP truth without ERP logins.
  • 04 Create sales orders in Acumatica from e-commerce platforms and sync shipment and tracking status back to the storefront.

Common sync patterns

Migration without a hard cutover

When one system is replacing the other, run both in parallel with records matching until the switch is complete.

One customer and vendor master

Where both systems keep records of the same organizations, corrections made in either propagate to the other.

Subsidiary to headquarters

Where Adyen serves a business unit and Acumatica is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

What you can sync between Acumatica and Adyen

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.

Acumatica objects Adyen objects How this pairing syncs
Payments Customer payment records reconciled against invoices from payment platforms. 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. 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.
Journal Transactions GL entries replicated into reporting databases. 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. Journal Transactions is specific to Acumatica and Users and API Credentials to Adyen — each maps to any object or custom field on the other side.
Projects Project cost and billing structures synced with delivery tools. Webhook Configurations Per-company or per-merchant webhook subscriptions (Management API); created, listed, and updated to control which events Adyen sends and to which endpoint and HMAC key. Projects is specific to Acumatica and Webhook Configurations to Adyen — each maps to any object or custom field on the other side.
Opportunities and Cases Built-in CRM records synced with external sales and support tools. Settlement Detail Reports Downloadable reports of settled transactions, fees, and payouts per merchant account; read-only, delivered when a report webhook fires, and loaded for finance reconciliation. Opportunities and Cases is specific to Acumatica and Settlement Detail Reports to Adyen — each maps to any object or custom field on the other side.
Customers AR master data synced with CRMs and billing tools. 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. Customers is specific to Acumatica and Modifications (Captures, Refunds, Cancels) to Adyen — each maps to any object or custom field on the other side.
Vendors Supplier records aligned with procurement and AP automation. 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. Vendors is specific to Acumatica and Payment Links to Adyen — each maps to any object or custom field on the other side.

How changes propagate between Acumatica and Adyen

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.

Acumatica Adyen Sub-second propagation

DetectionAcumatica notifies Stacksync of record changes through webhook events. Push notifications configurable on data changes, plus polling on LastModifiedDateTime fields.

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

Adyen Acumatica 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 Acumatica 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.
