Why teams connect Adyen and Affinity

Sync customers, invoices, and payment status between Adyen and Affinity in real time, so sales sees the money and finance sees the relationship.

Finance and sales describe the same customers in different systems. Affinity knows the relationship: who the contacts are and what is in motion with the account. Adyen knows the money: what was invoiced, what was paid, what is overdue. When the two are connected only by exports, each side works partly blind.

Stacksync links Users and API Credentials, Webhook Configurations, Settlement Detail Reports, Payments in Adyen to List Entries, Persons, Organizations, Opportunities in Affinity with bi-directional, real-time sync. New customers, updated billing details, invoice status, and payment activity move in whichever direction you configure, field by field, with conflicts resolved by rules you set. The result is one version of each customer, visible from both sides.

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 notes and reminders into project or task systems used outside the deal team.
  • 04 Mirror deal-flow lists into a warehouse or BI tool for pipeline and portfolio reporting.

Common sync patterns

Collections with context

Finance sees the account owner and relationship history from Affinity when chasing a balance, and sales sees that the chase is happening.

Where Affinity tracks deals: closed-won creates the finance record

A won opportunity creates or updates the customer in Adyen with the right billing details, so invoicing starts without re-keying.

Payment status on the account

Invoice and payment status from Adyen appears on the account in Affinity, so reps see overdue balances before they promise the next order.

How changes propagate between Adyen and Affinity

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

Affinity Adyen Sub-second propagation

DetectionAffinity notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, supplemented by polling.

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.
  • Affinity: Subject to the platform's published API rate limits.
