Two-way sync
Changes in Adyen or NextGen Healthcare instantly reflect in both systems. No stale data, no manual imports.
Keep Adyen and NextGen Healthcare in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Adyen holds the financial truth: who the customers are, what they were billed, what they paid. NextGen Healthcare 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 Payment Links, Merchant Accounts, Stores, Users and API Credentials in Adyen and Clinical Documents, Medications & Allergies, Lab Results, Insurance / Coverage in NextGen Healthcare in sync, bi-directionally and in real time. Whatever records NextGen Healthcare 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.
Payment and charge activity flows into Adyen as it happens, so the books reflect reality without manual reconciliation.
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.
Figures teams rely on, like customer status or outstanding balances, stay current wherever NextGen Healthcare surfaces them instead of going stale after a one-time paste.
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 | NextGen Healthcare objects | How this pairing syncs | |
|---|---|---|---|
| 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. | Charges & Billing Practice-management financial data synced for revenue-cycle analytics. | Payment Links is specific to Adyen and Charges & Billing to NextGen Healthcare — 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. | Patients Demographic records synced to CRMs and engagement tools for outreach and intake. | Merchant Accounts is specific to Adyen and Patients to NextGen Healthcare — 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. | Appointments Schedule data read and written for reminders, self-scheduling, and capacity reporting. | Stores is specific to Adyen and Appointments to NextGen Healthcare — 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. | Encounters Visit records landed in analytics stores for utilization and quality reporting. | Users and API Credentials is specific to Adyen and Encounters to NextGen Healthcare — each maps to any object or custom field on the other side. | |
| Webhook Configurations Per-company or per-merchant webhook subscriptions (Management API); created, listed, and updated to control which events Adyen sends and to which endpoint and HMAC key. | Providers Clinician and location directories kept consistent across scheduling and web systems. | Webhook Configurations is specific to Adyen and Providers to NextGen Healthcare — each maps to any object or custom field on the other side. | |
| Settlement Detail Reports Downloadable reports of settled transactions, fees, and payouts per merchant account; read-only, delivered when a report webhook fires, and loaded for finance reconciliation. | Clinical Documents Notes and attachments exchanged with referral and document-management workflows. | Settlement Detail Reports is specific to Adyen and Clinical Documents to NextGen Healthcare — each maps to any object or custom field on the other side. |
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.
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 NextGen Healthcare through its API, with automatic retries and rate-limit backoff.
DetectionStacksync polls NextGen Healthcare for changes on an incremental schedule, reading only records changed since the previous pass. Polling, typically filtering on last-updated timestamps.

Yes. Stacksync provides a managed, real-time two-way integration between Adyen and NextGen Healthcare: authenticate both systems, choose the objects to sync (such as Adyen's Payment Links and Merchant Accounts), map fields visually, and changes propagate both ways in milliseconds — no code required.
Adyen: REST APIs on adyen.com - Checkout (/checkout/v71), Management (/v3), Balance Platform / Configuration, Transfers, Payouts, and Reports, with standard webhooks for events. Authentication: API key in the X-API-Key header per web service or Balance Platform user (primary for Checkout, Management, and Balance Platform); Basic auth for classic web-service users; OAuth 2.0 for partner integrations; client keys are client-side only. NextGen Healthcare: REST API, including FHIR-based endpoints published through NextGen's developer API program. Authentication: OAuth 2.0. Stacksync manages authentication, retries, and rate limits on both sides.
Adyen: Adyen does not publish fixed numeric API rate limits; excessive requests return HTTP 429 (the Management API surfaces 'too many requests' in the error detail), and clients are expected to apply exponential backoff. NextGen Healthcare: The platform combines EHR and practice management, so both clinical data and scheduling/billing data are in integration scope. Stacksync's field mapping accounts for these differences between Adyen and NextGen Healthcare without custom code.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Adyen and NextGen Healthcare records are not retained after a sync operation.
