Why teams connect Adyen and ClickHouse

Land the financial records from Adyen in ClickHouse continuously, and write results back, without building or maintaining a pipeline.

Finance data belongs in the warehouse: revenue, invoices, payments, and customers joined with everything else the business measures. Getting it there usually means an extraction pipeline that breaks quietly and delivers yesterday's numbers.

Stacksync syncs Users and API Credentials, Webhook Configurations, Settlement Detail Reports, Payments from Adyen into tables in ClickHouse in real time, and the connection works in both directions: values computed in ClickHouse can be written back to fields in Adyen where you want them operational. Schema changes are handled, API limits are managed, and the sync is something you configure rather than code you maintain.

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 Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • 04 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.

Common sync patterns

Finance analytics without ETL

Invoices, payments, and customer records from Adyen arrive in ClickHouse as queryable tables, current within seconds instead of a day behind.

Revenue joined with everything else

Analysts combine Adyen's financial records with product, marketing, or operational data already in ClickHouse for reporting the finance system cannot do alone.

Write-back of computed fields

Scores or segments computed in ClickHouse, like payment-risk flags or customer tiers, sync back onto records in Adyen where the finance team can act on them.

What you can sync between Adyen and ClickHouse

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 ClickHouse objects How this pairing syncs
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. Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Webhook Configurations is specific to Adyen and Dictionaries to ClickHouse — 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. Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Settlement Detail Reports is specific to Adyen and Tables (MergeTree family) to ClickHouse — 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. Databases Namespaces that group tables and scope permissions for sync users. Payments is specific to Adyen and Databases to ClickHouse — 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. Views Saved queries used as curated, read-only sync sources. Modifications (Captures, Refunds, Cancels) is specific to Adyen and Views to ClickHouse — 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. Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Payment Links is specific to Adyen and Materialized views to ClickHouse — 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. Distributed tables Query-routing tables over cluster shards in self-managed deployments. Merchant Accounts is specific to Adyen and Distributed tables to ClickHouse — each maps to any object or custom field on the other side.

How changes propagate between Adyen and ClickHouse

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 ClickHouse 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 ClickHouse as a row-level write, with types converted between the two schemas.

ClickHouse Adyen Interval-based propagation

DetectionStacksync polls ClickHouse for changes on an incremental schedule, reading only records changed since the previous pass. No log-based CDC for consumers.

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.
