Why teams connect Adyen and Marketo
Put revenue reality behind every campaign: Adyen and Marketo share the same customers, contacts, and billing status in real time, in both directions.
Adyen records the money — who pays, how much, and whether they are current; Marketo decides who hears from the business and what they hear. The two overlap wherever the same customers and contacts matter to both, and when that overlap is bridged by CSV exports or an overnight batch, campaigns target on stale billing data and finance works from lists marketing has already changed underneath it.
Stacksync syncs Webhook Configurations, Settlement Detail Reports, Payments, Modifications (Captures, Refunds, Cancels) in Adyen with Opportunities and Opportunity Roles, Custom Objects, Activities and Lead Changes, Static Lists in Marketo field by field, in real time, and in both directions. You decide which system owns which fields — finance keeps the revenue and payment truth, marketing keeps consent and engagement — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.
Common use cases
- 01 Load Settlement Detail Reports into a warehouse to break out fees, interchange, and net payouts by merchant account for finance and treasury reporting.
- 02 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.
- 03 Sync Opportunities and Opportunity Roles into Marketo so revenue and pipeline data can drive account-aware nurture and reporting.
- 04 Two-way sync Marketo Leads with a Postgres or warehouse table, matched on email, so RevOps queries and updates marketing profiles in SQL while marketers keep working in Marketo.
Common sync patterns
Where Marketo captures new people: clean records flow to finance
Registrants, form fills, or leads created in Marketo create or update the matching customer or contact in Adyen, so billing and reporting start from accurate details without re-entry.
Where Adyen tracks lifecycle state: keep Marketo current
Trial, renewal, churn, or payment state from Adyen updates the contact in Marketo, so lifecycle campaigns and audience suppression run on current billing reality.
Consent and contact details stay aligned
Email, phone, address, and opt-out flags kept in either system stay consistent in the other, so every send and record honors the latest preferences.
What you can sync between Adyen and Marketo
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 | Marketo 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. | Leads Core person records (called Leads/People), deduped on email address by default or a configured dedupe field; read via GET /rest/v1/leads.json with a filterType, upserted via POST /rest/v1/leads.json (action createOrUpdate/createOnly/updateOnly), bulk-imported via CSV through POST /bulk/v1/leads.json, and bulk-exported via /bulk/v1/leads/export/create.json. | Payments is specific to Adyen and Leads to Marketo — 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. | Companies Company records linked to Leads via a company link field; read and upserted through /rest/v1/companies.json, typically mastered in a CRM or ERP and written into Marketo for account context. | Modifications (Captures, Refunds, Cancels) is specific to Adyen and Companies to Marketo — 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. | Opportunities and Opportunity Roles Revenue objects synced via /rest/v1/opportunities.json and /rest/v1/opportunities/roles.json; roles associate an opportunity with a Lead, so pipeline data can drive nurture and scoring. | Payment Links is specific to Adyen and Opportunities and Opportunity Roles to Marketo — each maps to any object or custom field on the other side. | |
| Merchant Accounts Company and merchant account entities in the Management API; read and updated to keep account configuration, payment-method settings, and capabilities aligned with internal systems. | Custom Objects Auxiliary data tables described via /rest/v1/customobjects.json and read/written via /rest/v1/customobjects/{apiName}.json, linked to Leads by a dedupe/link field so campaigns branch on records like purchases or subscriptions. | Merchant Accounts is specific to Adyen and Custom Objects to Marketo — each maps to any object or custom field on the other side. | |
| Stores Physical and online store entities under a merchant account (Management API); full CRUD, so new locations and their payment-method configuration can be provisioned from an internal admin source. | Activities and Lead Changes Engagement feed (opens, clicks, form fills, Data Value Changes) read via GET /rest/v1/activities.json using a paging token from /rest/v1/activities/pagingtoken.json (sinceDatetime), plus Get Lead Changes and Get Deleted Leads; read-only, also available via async Bulk Activity Extract. | Stores is specific to Adyen and Activities and Lead Changes to Marketo — each maps to any object or custom field on the other side. | |
| 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. | Static Lists Named static lists; read via /rest/v1/lists.json, with Leads added or removed via POST and DELETE on /rest/v1/lists/{listId}/leads.json to control campaign membership from lifecycle logic computed downstream. | Users and API Credentials is specific to Adyen and Static Lists to Marketo — each maps to any object or custom field on the other side. |
How changes propagate between Adyen and Marketo
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 Marketo 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 Marketo through its API, with automatic retries and rate-limit backoff.
Marketo Adyen Interval-based propagation
DetectionStacksync polls Marketo for changes on an incremental schedule, reading only records changed since the previous pass. Polling: Get Lead Changes and Get Lead Activities from a paging token seeded by a sinceDatetime, plus Get Deleted Leads, or Bulk Extract filtered on.
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.
- Marketo: Interactive calls are capped at 100 per 20 seconds (error 606) and a maximum of 10 concurrent calls (error 615) per instance, neither increasable; a default daily quota of 50,000 calls (increasable, resets midnight CST) applies. Bulk Extract shares a 500 MB/day export quota across data types with at most 2 concurrent jobs and 10 queued.

- Change detection
- Standard webhooks for payment events (AUTHORISATION, CAPTURE, REFUND, CHARGEBACK, and more) plus Management, Balance Platform, and report webhooks; all HMAC-signed and acknowledged with a 2xx within about 10 seconds. No database-style CDC; historical transactions come from Settlement Detail Reports

Marketo
- Integration surface
- Marketo REST API (JSON over HTTPS) for Leads, Companies, Opportunities, Custom Objects, Activities, Lists, Programs, and Campaigns, plus an asynchronous Bulk Import (leads) and Bulk Extract (leads/activities/program members/custom objects) API and an Asset REST API for emails, forms, and landing pages
- Authentication
- OAuth 2.0 client_credentials (2-legged): GET the Identity URL /oauth/token?grant_type=client_credentials with a Custom Service client_id and client_secret to receive an access token valid for 3600 seconds, then send it as Authorization: Bearer on each call. The instance base URL is https://{munchkinId}.mktorest.com; passing the token as an access_token query parameter is deprecated (removal July 31, 2026).
- Change detection
- Polling: Get Lead Changes and Get Lead Activities from a paging token seeded by a sinceDatetime, plus Get Deleted Leads, or Bulk Extract filtered on createdAt/updatedAt. Marketo's Webhooks are Smart Campaign flow-step outbound HTTP calls to a URL, not a general record-change subscription, so there is no push feed of arbitrary CRUD.

Adyen: Standard webhooks are HMAC-signed with a per-webhook key that must be verified, and Adyen expects a 2xx acknowledgment within about 10 seconds (classic standard notifications acknowledge with an [accepted] response body). Marketo: Interactive calls are limited to 100 per 20 seconds (error 606) and 10 concurrent calls (error 615) per instance, neither of which can be increased, under a default 50,000-calls-per-day quota that resets at midnight CST. Stacksync's field mapping accounts for these differences between Adyen and Marketo without custom code.
