Why teams connect Gatekeeper and Sage 100
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Gatekeeper and Sage 100.
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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Vendors, Inventory Items, Sales Orders, AR Invoices in Sage 100 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 Push generated documents into Gatekeeper Files, or pull executed contract PDFs and compliance evidence out into a document store or archive.
- 02 Stream workflow-form data - intake requests, vendor onboarding, risk assessments - into an operational database for cycle-time and compliance reporting.
- 03 Replicate GL and sales history to a warehouse or Postgres database for reporting off the on-premise system.
- 04 Sync customers, invoices, and payment status into a CRM so sales sees AR standing without opening the ERP.
Common sync patterns
Where Gatekeeper faces customers and Sage 100 carries account records
Order, invoice, or account status from Sage 100 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 Sage 100 as they occur, keeping the enterprise records current without manual entry.
Where Sage 100 is the HR or people system of record
Worker and organization data from Sage 100 stays current in Gatekeeper, so the tools people use daily reflect the org as it actually is.
What you can sync between Gatekeeper and Sage 100
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 | Sage 100 objects | How this pairing syncs | |
|---|---|---|---|
| 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. | Journal Entries Posted GL activity replicated to warehouses for FP&A. | Workflow form data is specific to Gatekeeper and Journal Entries to Sage 100 — 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. | Customers AR customer master records synced to CRMs for account and credit visibility. | Custom data groups is specific to Gatekeeper and Customers to Sage 100 — 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. | Vendors AP vendor master records synced with procurement and payment tools. | Users is specific to Gatekeeper and Vendors to Sage 100 — 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. | Inventory Items Item master with pricing and quantities, synced to e-commerce catalogs. | Categories is specific to Gatekeeper and Inventory Items to Sage 100 — 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. | Sales Orders Order headers and lines, the usual write target for web and EDI orders. | Contracts is specific to Gatekeeper and Sales Orders to Sage 100 — each maps to any object or custom field on the other side. | |
| Vendors (Suppliers) Company records for counterparties and suppliers with onboarding status, compliance, risk, contacts, and spend; read and written to keep vendor master data aligned with a CRM or ERP. | AR Invoices Billing documents synced outward for payment status and revenue reporting. | Vendors (Suppliers) is specific to Gatekeeper and AR Invoices to Sage 100 — each maps to any object or custom field on the other side. |
How changes propagate between Gatekeeper and Sage 100
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 Sage 100 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 applied to Sage 100 as a row-level write, with types converted between the two schemas.
Sage 100 Gatekeeper Interval-based propagation
DetectionStacksync polls Sage 100 for changes on an incremental schedule, reading only records changed since the previous pass. Scheduled polling.
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.

How the Gatekeeper and Sage 100 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.

FAQ
Gatekeeper and Sage 100 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Gatekeeper and Sage 100: authenticate both systems, choose the objects to sync (such as Gatekeeper's Workflow form data and Custom data groups), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Gatekeeper: Write access is per API key per endpoint: when you create a key you choose read-only or write for each object, so the API is write-capable and can create and update records rather than only export them. Sage 100: Sage 100 (formerly MAS 90/200) is an on-premise ERP; its data files are exposed for reads through a ProvideX ODBC driver with module-prefixed tables such as AR_Customer and SO_SalesOrderHeader. Stacksync's field mapping accounts for these differences between Gatekeeper and Sage 100 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 Gatekeeper and Sage 100 records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Gatekeeper and Sage 100 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Gatekeeper–Sage 100 integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Gatekeeper and Sage 100. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Gatekeeper: 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. On Sage 100: Scheduled polling; no webhooks or change log on the integration surface. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
