Why teams connect Adyen and Sage Intacct

Keep Adyen and Sage Intacct agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.

A dedicated finance tool and an ERP end up side by side for practical reasons: a subsidiary runs lighter software than headquarters, billing runs in a specialist system while the enterprise system holds the wider view, or the company is mid-migration and both are live. Whatever the split, the two systems describe overlapping customers and transactions, and that overlap drifts without a live connection.

Stacksync syncs Webhook Configurations, Settlement Detail Reports, Payments, Modifications (Captures, Refunds, Cancels) in Adyen with Customers, Vendors, AR Invoices, AP Bills in Sage Intacct in real time and in both directions. You decide which system wins on which field, and every change made in one is reflected in the other within seconds instead of at the next batch run.

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 Replicate GL and journal detail, with full dimension tags, to a warehouse for FP&A reporting.
  • 04 Sync vendors and AP bills with procurement and spend management tools.

Common sync patterns

Where Adyen handles billing: invoices land in Sage Intacct

Invoices and payment activity from the billing side post through to the enterprise system automatically.

Migration without a hard cutover

When one system is replacing the other, run both in parallel with records matching until the switch is complete.

One customer and vendor master

Where both systems keep records of the same organizations, corrections made in either propagate to the other.

What you can sync between Adyen and Sage Intacct

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 Sage Intacct objects How this pairing syncs
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. Payments AR and AP payment records synced for cash application and status reporting. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
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. Customers AR masters synced bi-directionally with CRMs like Salesforce and HubSpot. Users and API Credentials is specific to Adyen and Customers to Sage Intacct — 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. Vendors AP masters kept aligned with procurement and payment platforms. Webhook Configurations is specific to Adyen and Vendors to Sage Intacct — 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. AR Invoices Billing documents created from upstream order or subscription data. Settlement Detail Reports is specific to Adyen and AR Invoices to Sage Intacct — 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. AP Bills Payables documents written from procurement tools and OCR pipelines. Modifications (Captures, Refunds, Cancels) is specific to Adyen and AP Bills to Sage Intacct — 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. Order Entry Transactions Configurable sales transaction documents used as write targets for order-to-cash syncs. Payment Links is specific to Adyen and Order Entry Transactions to Sage Intacct — each maps to any object or custom field on the other side.

How changes propagate between Adyen and Sage Intacct

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

Sage Intacct Adyen Interval-based propagation

DetectionStacksync polls Sage Intacct for changes on an incremental schedule, reading only records changed since the previous pass. Polling on WHENMODIFIED audit fields.

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.
