Why teams connect Adyen and Apollo.io

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

Finance and sales describe the same customers in different systems. Apollo.io 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 Settlement Detail Reports, Payments, Modifications (Captures, Refunds, Cancels), Payment Links in Adyen to People (database records), Sequences, Deals (Opportunities), Tasks and calls in Apollo.io 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 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • 04 Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.

Common sync patterns

Billing detail changes flow back

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

Collections with context

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

Where Apollo.io 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 Apollo.io

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

Apollo.io Adyen Interval-based propagation

DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.

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.
  • Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
