Why teams connect Adyen and Sysaid

Connect the financial records in Adyen with the work happening in Sysaid, 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. Sysaid 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 Payments, Modifications (Captures, Refunds, Cancels), Payment Links, Merchant Accounts in Adyen and Service Requests, Problems, Changes, Users in Sysaid in sync, bi-directionally and in real time. Whatever records Sysaid 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 Load Settlement Detail Reports into a warehouse to break out fees, interchange, and net payouts by merchant account for finance and treasury reporting.
  • 02 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.
  • 03 Sync Users, Groups, and Companies from an HRIS or identity provider so requester and agent records, departments, and managers stay current in SysAid.
  • 04 Mirror Assets and Configuration Items with an external CMDB or asset database so inventory and ticket linkage share one source of truth.

Common sync patterns

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

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

Where Sysaid 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 Sysaid 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 Sysaid

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 Sysaid 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. Assets Hardware and software inventory; read out to a warehouse or written from a discovery or CMDB source of truth. Settlement Detail Reports is specific to Adyen and Assets to Sysaid — 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. Configuration Items (CIs) CMDB entries and their relationships; synced with an external CMDB or asset database for one inventory view. Payments is specific to Adyen and Configuration Items (CIs) to Sysaid — 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. Companies Customer and department organizations that scope tickets and users; mapped to Accounts in a CRM or org tables in a database. Modifications (Captures, Refunds, Cancels) is specific to Adyen and Companies to Sysaid — 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. Custom Fields Org-specific fields on service records, discoverable through the API so mappings can be generated without hardcoding names. Payment Links is specific to Adyen and Custom Fields to Sysaid — 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. Incidents Break/fix tickets under /api/v1/sr with type=incident; created and updated two-way with status, priority, assignee, category, and SLA fields. Merchant Accounts is specific to Adyen and Incidents to Sysaid — 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. Service Requests Catalog and help-desk requests on the same /sr endpoint (type=request); written or read so fulfillment can be driven from another system. Stores is specific to Adyen and Service Requests to Sysaid — each maps to any object or custom field on the other side.

How changes propagate between Adyen and Sysaid

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

Sysaid Adyen Sub-second propagation

DetectionSysaid notifies Stacksync of record changes through webhook events. Webhooks (beta) push sr.created and sr.updated events with changed-field diffs and an X-Sysaid-Signature.

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.
  • Sysaid: Requests are throttled per the X-RateLimit-Limit / -Remaining / -Reset headers; list calls are paginated with a limit parameter and each org is capped at 100 application keys.

How the Adyen and Sysaid connectors work

Adyen

Integration surface
REST APIs on adyen.com - Checkout (/checkout/v71), Management (/v3), Balance Platform / Configuration, Transfers, Payouts, and Reports, with standard webhooks for events
Authentication
API key in the X-API-Key header per web service or Balance Platform user (primary for Checkout, Management, and Balance Platform); Basic auth for classic web-service users; OAuth 2.0 for partner integrations; client keys are client-side only
Change detection
Standard webhooks for payment events (AUTHORISATION, CAPTURE, REFUND, CHARGEBACK, and more) plus Management, Balance Platform, and report webhooks; all HMAC-signed and acknowledged with a 2xx within about 10 seconds. No database-style CDC; historical transactions come from Settlement Detail Reports

Rate limits
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.

Sysaid

Integration surface
REST API (JSON)
Authentication
Client-credentials app keys: an application key (clientId/clientSecret) is created via /v1/application-keys, then exchanged at /v1/access-tokens for a bearer token (default 24h, up to 30 days); an x-sysaid-accountid header scopes the account. Legacy V0 uses session-cookie login.
Change detection
Webhooks (beta) push sr.created and sr.updated events with changed-field diffs and an X-Sysaid-Signature; otherwise poll the /sr endpoint filtering on update_time.gte.
