Why teams connect Adyen and ConnectWise

Connect the financial records in Adyen with the work happening in ConnectWise, 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. ConnectWise 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 Users and API Credentials, Webhook Configurations, Settlement Detail Reports, Payments in Adyen and Opportunities, Agreements, Projects, Time Entries in ConnectWise in sync, bi-directionally and in real time. Whatever records ConnectWise 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 Reconcile ConnectWise invoices and agreements against the accounting system to catch billing gaps.
  • 04 Keep configuration (asset) records aligned with an external CMDB or RMM tool.

Common sync patterns

Where ConnectWise 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 ConnectWise 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.

Where ConnectWise tracks people or companies: one identity

A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.

How changes propagate between Adyen and ConnectWise

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

ConnectWise Adyen Sub-second propagation

DetectionConnectWise notifies Stacksync of record changes through webhook events. Callbacks (webhooks) on record changes, supplemented by polling on last-updated 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.
  • ConnectWise: Subject to the platform's API rate limits per company and integration.
