Why teams connect Adyen and AWS S3

Land the financial records from Adyen in AWS S3 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 Modifications (Captures, Refunds, Cancels), Payment Links, Merchant Accounts, Stores from Adyen into tables in AWS S3 in real time, and the connection works in both directions: values computed in AWS S3 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 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.
  • 02 Provision Stores, Users, and API credentials through the Management API from an internal admin app or IdP so new locations and staff get the right Adyen access automatically.
  • 03 Export synced operational data to S3 as files feeding a data lake or downstream batch jobs.
  • 04 Trigger incremental sync runs from S3 event notifications when new files land in a prefix.

Common sync patterns

Finance analytics without ETL

Invoices, payments, and customer records from Adyen arrive in AWS S3 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 AWS S3 for reporting the finance system cannot do alone.

Write-back of computed fields

Scores or segments computed in AWS S3, 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 AWS S3

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 AWS S3 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. Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. Stores is specific to Adyen and Prefixes to AWS S3 — 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. Object Metadata System and user-defined metadata read alongside object contents. Users and API Credentials is specific to Adyen and Object Metadata to AWS S3 — 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. Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing. Webhook Configurations is specific to Adyen and Object Versions to AWS S3 — 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. Event Notifications Notifications on object creation or deletion that trigger incremental processing. Settlement Detail Reports is specific to Adyen and Event Notifications to AWS S3 — 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. Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Payments is specific to Adyen and Access Points to AWS S3 — 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. Multipart Uploads The mechanism used to write large export files reliably. Modifications (Captures, Refunds, Cancels) is specific to Adyen and Multipart Uploads to AWS S3 — each maps to any object or custom field on the other side.

How changes propagate between Adyen and AWS S3

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 AWS S3 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 AWS S3 through its API, with automatic retries and rate-limit backoff.

AWS S3 Adyen Sub-second propagation

DetectionAWS S3 notifies Stacksync of record changes through webhook events. S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge.

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.
  • AWS S3: Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes.
