Why teams connect Adyen and SAP

Keep Adyen and SAP 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 Settlement Detail Reports, Payments, Modifications (Captures, Refunds, Cancels), Payment Links in Adyen with Sales Orders, Purchase Orders, Outbound Deliveries, Billing Documents in SAP 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 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 Publish plant-level inventory to e-commerce and planning systems on change or on schedule.
  • 04 Replicate journal entries and billing documents to a warehouse for finance analytics without loading the ERP.

Common sync patterns

Subsidiary to headquarters

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

Where Adyen handles billing: invoices land in SAP

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

Migration without a hard cutover

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

What you can sync between Adyen and SAP

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 SAP objects How this pairing syncs
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. Outbound Deliveries Shipment documents synced to WMS, carriers, and customer portals. Stores is specific to Adyen and Outbound Deliveries to SAP — 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. Billing Documents Invoices read for AR status and replicated for revenue reporting. Users and API Credentials is specific to Adyen and Billing Documents to SAP — each maps to any object or custom field on the other side.
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. GL Accounts and Journal Entries Financial postings replicated to warehouses for group finance analytics. Webhook Configurations is specific to Adyen and GL Accounts and Journal Entries to SAP — each maps to any object or custom field on the other side.
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. Production Orders Manufacturing orders exchanged with MES and scheduling systems. Settlement Detail Reports is specific to Adyen and Production Orders to SAP — 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. Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. Payments is specific to Adyen and Inventory / Stock to SAP — 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. Cost Centers Controlling masters read for mapping costs in finance integrations. Modifications (Captures, Refunds, Cancels) is specific to Adyen and Cost Centers to SAP — each maps to any object or custom field on the other side.

How changes propagate between Adyen and SAP

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

SAP Adyen Sub-second propagation

DetectionSAP notifies Stacksync of record changes through webhook events. Business events via SAP Event Mesh on S/4HANA.

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.
  • SAP: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.
