Why teams connect Adyen and Plex ERP

Keep Adyen and Plex ERP 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 Payments, Modifications (Captures, Refunds, Cancels), Payment Links, Merchant Accounts in Adyen with Parts, Inventory, Production jobs, Sales orders in Plex ERP 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 Ingest AUTHORISATION, CAPTURE, REFUND, and CHARGEBACK webhooks into Postgres or a warehouse so finance reconciles Adyen settlements against orders in an ERP without manual report exports.
  • 02 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.
  • 03 Sync production and inventory data from Plex into a warehouse or Postgres for plant-level analytics.
  • 04 Keep customers, parts, and pricing aligned between Plex and the CRM the sales team uses.

Common sync patterns

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 Plex ERP is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.

Where Adyen handles billing: invoices land in Plex ERP

Invoices and payment activity from the billing side post through to the enterprise system automatically.

What you can sync between Adyen and Plex ERP

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 Plex ERP objects How this pairing syncs
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. Suppliers Vendor records aligned with procurement and AP tools Settlement Detail Reports is specific to Adyen and Suppliers to Plex ERP — each maps to any object or custom field on the other side.
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. Shipments Outbound logistics records synced to trading partners and tracking systems Payments is specific to Adyen and Shipments to Plex ERP — 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. Quality records Checksheet and inspection data pulled into plant dashboards Modifications (Captures, Refunds, Cancels) is specific to Adyen and Quality records to Plex ERP — 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. Parts Item master records shared with CRM, e-commerce, and planning tools Payment Links is specific to Adyen and Parts to Plex ERP — 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. Inventory On-hand balances and locations replicated for visibility outside the plant system Merchant Accounts is specific to Adyen and Inventory to Plex ERP — 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. Production jobs Shop-floor work records combining ERP and MES data for output reporting Stores is specific to Adyen and Production jobs to Plex ERP — each maps to any object or custom field on the other side.

How changes propagate between Adyen and Plex ERP

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 Plex ERP 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 Plex ERP through its API, with automatic retries and rate-limit backoff.

Plex ERP Adyen Interval-based propagation

DetectionStacksync polls Plex ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

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.
  • Plex ERP: Subject to the platform's API rate limits.
