Why teams connect Adyen and Supabase

Work with Adyen's financial data straight from Supabase: 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 Schemas, auth.users, Row Level Security Policies, JSONB Columns in Supabase and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Supabase, 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 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.
  • 02 Load Settlement Detail Reports into a warehouse to break out fees, interchange, and net payouts by merchant account for finance and treasury reporting.
  • 03 Mirror billing and subscription records into Supabase tables the application can join directly
  • 04 Reflect auth.users state into support and CRM systems so teams see account status without querying the database

Common sync patterns

Internal tools without API plumbing

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

Write back safely

Updates written to the synced tables in Supabase propagate into Adyen, so automations can create or correct finance records without custom integration code.

React to financial events

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

What you can sync between Adyen and Supabase

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 Supabase 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. Storage Object Metadata File metadata rows that can be joined to synced application data. Webhook Configurations is specific to Adyen and Storage Object Metadata to Supabase — 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 Standard Postgres tables; the primary two-way sync target. Settlement Detail Reports is specific to Adyen and Tables to Supabase — 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. Views Read-side projections exposed to outbound syncs. Payments is specific to Adyen and Views to Supabase — 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. Schemas Namespaces (public and custom) that scope sync access. Modifications (Captures, Refunds, Cancels) is specific to Adyen and Schemas to Supabase — 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. auth.users Managed authentication users, often mirrored into CRM or support systems. Payment Links is specific to Adyen and auth.users to Supabase — 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. Row Level Security Policies Row-level access rules that govern what the REST layer exposes. Merchant Accounts is specific to Adyen and Row Level Security Policies to Supabase — each maps to any object or custom field on the other side.

How changes propagate between Adyen and Supabase

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

Supabase Adyen Sub-second propagation

DetectionSupabase pushes changes as they happen — webhook events backed by change data capture. Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime.

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.
  • Supabase: SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits.
