Two-way sync
Changes in Gatekeeper or Sage 300 instantly reflect in both systems. No stale data, no manual imports.
Keep Gatekeeper and Sage 300 in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.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 Users, Categories, Contracts, Vendors (Suppliers) in Gatekeeper with AP Vendors, GL Accounts, Journal Batches, Order Entry Orders in Sage 300 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.
Order, invoice, or account status from Sage 300 appears alongside the customer in Gatekeeper, so front-line teams answer from live data.
Payment events sync into Sage 300 as they occur, keeping the enterprise records current without manual entry.
Worker and organization data from Sage 300 stays current in Gatekeeper, so the tools people use daily reflect the org as it actually is.
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 300 objects | How this pairing syncs | |
|---|---|---|---|
| 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. | AP Vendors Payables vendor master synced with procurement and payment systems. | Vendors (Suppliers) is specific to Gatekeeper and AP Vendors to Sage 300 — each maps to any object or custom field on the other side. | |
| 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. | GL Accounts Chart of accounts read for transaction mapping across integrations. | Files is specific to Gatekeeper and GL Accounts to Sage 300 — 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. | Journal Batches GL entries staged in batches that must be posted; a common write target for external systems. | Workflow form data is specific to Gatekeeper and Journal Batches to Sage 300 — 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. | Order Entry Orders Sales orders written from e-commerce or EDI feeds. | Custom data groups is specific to Gatekeeper and Order Entry Orders to Sage 300 — 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. | Purchase Orders Procurement documents read for spend visibility and receiving. | Users is specific to Gatekeeper and Purchase Orders to Sage 300 — 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 costing and quantities, synced to storefronts and WMS. | Categories is specific to Gatekeeper and Inventory Items to Sage 300 — 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.
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 300 as a row-level write, with types converted between the two schemas.
DetectionStacksync polls Sage 300 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.
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Gatekeeper–Sage 300 connection.
Changes in Gatekeeper or Sage 300 instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Gatekeeper or Sage 300 data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Gatekeeper or Sage 300 record.
Track your Gatekeeper ⇄ Sage 300 sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Gatekeeper and Sage 300.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Gatekeeper and Sage 300 with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Gatekeeper and Sage 300 objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Gatekeeper and Sage 300: authenticate both systems, choose the objects to sync (such as Gatekeeper's Vendors (Suppliers) and Files), map fields visually, and changes propagate both ways in milliseconds — no code required.
On the Gatekeeper side: Users, Categories, Contracts, Vendors (Suppliers), plus custom fields where Gatekeeper exposes them. On the Sage 300 side: AP Vendors, GL Accounts, Journal Batches, Order Entry Orders. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for Gatekeeper and Sage 300: Where Gatekeeper faces customers and Sage 300 carries account records; Where Gatekeeper collects payments: transactions post through; Where Sage 300 is the HR or people system of record. Order, invoice, or account status from Sage 300 appears alongside the customer in Gatekeeper, so front-line teams answer from live data.
Gatekeeper: 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. Sage 300: Sage 300 Web API (REST) on newer releases; .NET/COM SDK and direct SQL Server access on-prem. Authentication: Sage 300 user credentials (Basic auth on the Web API); database credentials for direct SQL reads. Stacksync manages authentication, retries, and rate limits on both sides.
Gatekeeper: There is no native developer webhook subscription API and no database CDC log; change detection is polling by updated-at. Event-driven automation lives in Gatekeeper's Workflow Engine and Interconnect, inside the platform. Sage 300: Sage 300 (formerly Accpac) stores each company's data in its own SQL Server database with module-prefixed tables, so direct SQL reads are a common integration path on-prem. Stacksync's field mapping accounts for these differences between Gatekeeper and Sage 300 without custom code.
