Why teams connect Gatekeeper and SAP S/4HANA

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Gatekeeper and SAP S/4HANA.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Gatekeeper is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs Custom data groups, Users, Categories, Contracts in Gatekeeper with Billing Documents (Invoices), Deliveries, Journal Entries, Customer / Supplier Roles in SAP S/4HANA bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

Common use cases

  • 01 Write contract or vendor records into Gatekeeper when a deal closes in the CRM to kick off downstream procurement and legal workflows.
  • 02 Two-way sync Contracts between Gatekeeper and an ERP or warehouse so value, renewal dates, owner, and status stay current without manual re-keying.
  • 03 Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.
  • 04 Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.

Common sync patterns

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.

Where Gatekeeper faces customers and SAP S/4HANA carries account records

Order, invoice, or account status from SAP S/4HANA appears alongside the customer in Gatekeeper, so front-line teams answer from live data.

Where Gatekeeper collects payments: transactions post through

Payment events sync into SAP S/4HANA as they occur, keeping the enterprise records current without manual entry.

What you can sync between Gatekeeper and SAP S/4HANA

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.

Gatekeeper objects SAP S/4HANA objects How this pairing syncs
Files Document files attached to contracts and vendors - executed PDFs, certificates, and compliance evidence; read to pull signed files and evidence out, or written to push generated documents in. Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs. Files is specific to Gatekeeper and Products / Materials to SAP S/4HANA — each maps to any object or custom field on the other side.
Workflow form data The structured data captured on Gatekeeper workflow forms (intake requests, vendor onboarding, risk assessments); exposed by the API since 2025 so form results sync into an operational database, not only contract and vendor records. Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility. Workflow form data is specific to Gatekeeper and Billing Documents (Invoices) to SAP S/4HANA — each maps to any object or custom field on the other side.
Custom data groups Customer-configured custom fields and data groups; because the JSON:API and its docs are dynamic, any custom data added in Configuration exposes the same read/write endpoints as the standard objects and syncs the same way. Deliveries Outbound delivery status synced to customer-facing systems for order tracking. Custom data groups is specific to Gatekeeper and Deliveries to SAP S/4HANA — each maps to any object or custom field on the other side.
Users Gatekeeper user and team records governed by role-based access; read to map contract and vendor owners, approvers, and internal contacts to CRM or HR records. Journal Entries Financial postings read into warehouses and consolidation tools for reporting. Users is specific to Gatekeeper and Journal Entries to SAP S/4HANA — each maps to any object or custom field on the other side.
Categories The classification taxonomy applied to contracts and vendors (type, department, business unit); synced so categorization stays consistent between Gatekeeper and downstream reporting or ERP dimensions. Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. Categories is specific to Gatekeeper and Customer / Supplier Roles to SAP S/4HANA — each maps to any object or custom field on the other side.
Contracts The core contract records holding value, key dates, renewal terms, status, type, owner, and the linked vendor; created, read, updated, and deleted so contract data moves two-way between Gatekeeper and a database, ERP, or CRM. Production Orders Manufacturing order status surfaced in planning and operations tools. Contracts is specific to Gatekeeper and Production Orders to SAP S/4HANA — each maps to any object or custom field on the other side.

How changes propagate between Gatekeeper and SAP S/4HANA

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.

Gatekeeper SAP S/4HANA Interval-based propagation

DetectionStacksync polls Gatekeeper for changes on an incremental schedule, reading only records changed since the previous pass. No native developer webhook subscription API and no database change-data-capture log.

DeliveryEach detected change is written to SAP S/4HANA through its API, with automatic retries and rate-limit backoff.

DeliveryEach detected change is written to Gatekeeper through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Gatekeeper: Gatekeeper publishes no fixed public per-minute request quota; throughput is governed per key by its endpoint permissions, and every call is recorded (parameters, payload, response) under API Logs for monitoring. Pace bulk writes and use JSON:API pagination on list endpoints.
  • SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.

How the Gatekeeper and SAP S/4HANA connectors work

Gatekeeper

Integration surface
RESTful API following the JSON:API specification, tenant-scoped with interactive docs at {tenant}.gatekeeperhq.com/api_docs and a published Postman collection. The API is dynamic: it exposes the standard Contract and Vendor objects plus any custom data groups and workflow-form data configured in the tenant.
Authentication
API keys created and managed under Configuration > API Keys and passed as a token; each key carries granular per-endpoint permissions set to read-only or write, so access is scoped per object. Multiple keys can be issued and revoked independently.
Change detection
No native developer webhook subscription API and no database change-data-capture log; detect changes by polling the JSON:API list endpoints filtered and sorted on updated-at timestamps. Gatekeeper's own event automation - Workflow Engine phase transitions and Interconnect process orchestration - runs inside the platform rather than as a subscribable webhook stream.
