Why teams connect Adyen and Attio

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

Finance and sales describe the same customers in different systems. Attio 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 Stores, Users and API Credentials, Webhook Configurations, Settlement Detail Reports in Adyen to People, Companies, Users, Deals in Attio 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 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.
  • 02 Create Adyen Payment Links from an invoicing or billing system and sync each link's paid or expired status back so accounts receivable sees payment without opening the Customer Area.
  • 03 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
  • 04 Run a two-way dual-run when migrating to Attio from another CRM.

Common sync patterns

Billing detail changes flow back

When a contact or address is corrected in Attio, Adyen gets the update before the next invoice goes out.

Collections with context

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

Where Attio 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.

How changes propagate between Adyen and Attio

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

Attio Adyen Sub-second propagation

DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.

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