Why teams connect Adyen and Unleashed Software

Keep Adyen and Unleashed Software 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 Stores, Users and API Credentials, Webhook Configurations, Settlement Detail Reports in Adyen with Warehouses, Stock Adjustments, Bills of Materials, Invoices in Unleashed Software 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 Mirror Purchase Orders and supplier data to a data warehouse for procurement reporting.
  • 04 Sync Customers bi-directionally with a CRM so credit terms and delivery addresses match everywhere.

Common sync patterns

Where Adyen handles billing: invoices land in Unleashed Software

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.

One customer and vendor master

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

How changes propagate between Adyen and Unleashed Software

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

Unleashed Software Adyen Interval-based propagation

DetectionStacksync polls Unleashed Software for changes on an incremental schedule, reading only records changed since the previous pass. Polling with modified-date filters on list endpoints.

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.
  • Unleashed Software: Subject to the platform's API rate limits; paginate list endpoints and batch where possible.
