Why teams connect Adyen and SQL Server

Work with Adyen's financial data straight from SQL Server: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Settlement Detail Reports, Payments, Modifications (Captures, Refunds, Cancels), Payment Links from Adyen into CDC Change Tables, Stored Procedures, Databases, Schemas in SQL Server and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against SQL Server, and rows your code writes or updates flow back into Adyen with validation, so the finance system stays the system of record.

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 Mirror on-premises ERP data held in SQL Server into cloud CRM and support systems
  • 04 Feed a cloud warehouse from SQL Server continuously using native CDC instead of SSIS batch jobs

Common sync patterns

React to financial events

Changes in Adyen appear in SQL Server as row changes, so you can trigger downstream logic with the database tooling you already use.

Query finance data like any other data

Customers, invoices, and payments from Adyen live in SQL Server as regular tables or collections your team can join, index, and query.

Internal tools without API plumbing

Build dashboards and back-office tools directly on SQL Server; Stacksync handles the API calls, rate limits, and retries against Adyen.

What you can sync between Adyen and SQL Server

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 SQL Server 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. Views Read-side projections used as outbound sync sources. Settlement Detail Reports is specific to Adyen and Views to SQL Server — 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. Columns Field-level mapping targets with T-SQL types. Payments is specific to Adyen and Columns to SQL Server — 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. Primary and Unique Keys Match keys for idempotent upserts and conflict handling. Modifications (Captures, Refunds, Cancels) is specific to Adyen and Primary and Unique Keys to SQL Server — 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. CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers. Payment Links is specific to Adyen and CDC Change Tables to SQL Server — 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. Stored Procedures T-SQL logic that can validate or post-process synced rows. Merchant Accounts is specific to Adyen and Stored Procedures to SQL Server — 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. Databases Instance-level databases that scope a sync's reads and writes. Stores is specific to Adyen and Databases to SQL Server — each maps to any object or custom field on the other side.

How changes propagate between Adyen and SQL Server

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 SQL Server 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 applied to SQL Server as a row-level write, with types converted between the two schemas.

SQL Server Adyen Sub-second propagation

DetectionChanges in SQL Server are captured at the source via change data capture — no polling loop against its API. SQL Server Native Change Data Capture (CDC).

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.
  • SQL Server: No API rate limits; throughput depends on instance resources, licensing tier, and connection limits.
