Why teams connect Adyen and Notion

Connect the financial records in Adyen with the work happening in Notion, so both stay current without exports or copy-paste.

Adyen holds the financial truth: who the customers are, what they were billed, what they paid. Notion is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.

Stacksync keeps Payment Links, Merchant Accounts, Stores, Users and API Credentials in Adyen and Files and attachments, Pages, Databases / Data sources, Properties in Notion in sync, bi-directionally and in real time. Whatever records Notion keeps and whatever events it produces, the overlap with Adyen is mapped field by field, and a change on either side shows up on the other within seconds.

There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.

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 Sync a Notion content-calendar database with Jira or Linear by mapping status and date properties both directions.
  • 04 Read Notion wiki Pages and their Blocks into a database or search index for internal knowledge retrieval.

Common sync patterns

Where Notion is a docs or knowledge workspace: reference data kept fresh

Figures teams rely on, like customer status or outstanding balances, stay current wherever Notion surfaces them instead of going stale after a one-time paste.

Where Notion handles customer conversations: billing context in view

Front-line teams see invoice and payment status from Adyen next to the customer they are helping, without logging into the finance system.

Where Notion collects payments or triggers charges: events land in Adyen

Payment and charge activity flows into Adyen as it happens, so the books reflect reality without manual reconciliation.

What you can sync between Adyen and Notion

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 Notion 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. Files and attachments File-property and file-block values. Notion-hosted URLs are temporary and expire, so files are re-fetched or copied at sync time. Settlement Detail Reports is specific to Adyen and Files and attachments to Notion — 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. Pages The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns. Payments is specific to Adyen and Pages to Notion — 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. Databases / Data sources Collections of pages with a typed property schema. Since the 2025-09-03 API a database is a container holding one or more data sources; syncs target a specific data_source_id. Modifications (Captures, Refunds, Cancels) is specific to Adyen and Databases / Data sources to Notion — 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. Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. Payment Links is specific to Adyen and Properties to Notion — 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. Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. Merchant Accounts is specific to Adyen and Blocks to Notion — 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. Formula and Rollup properties Values computed by Notion from other fields; read-only, so they are pulled out for reporting but never written back. Stores is specific to Adyen and Formula and Rollup properties to Notion — each maps to any object or custom field on the other side.

How changes propagate between Adyen and Notion

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

Notion Adyen Sub-second propagation

DetectionNotion notifies Stacksync of record changes through webhook events. Workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created.

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.
  • Notion: Average of ~3 requests/second per integration with some bursts; 429 with a Retry-After header when exceeded. Payloads capped at 500 KB and 1000 block elements.
