Why teams connect IBM AS/400 and Paylocity

Put your workforce data where your apps can reach it: IBM AS/400 and Paylocity share the same people, positions, and org structure in real time.

Paylocity is the system of record for the people side of the business — employees, candidates, roles, and the org structure around them. IBM AS/400 is where internal tools, dashboards, provisioning jobs, and analytics actually read and store records. The overlap is the workforce itself: Onboarding, Deductions (Pay Setup), Earnings (Pay Setup), Local and State Taxes in Paylocity need to exist as queryable Libraries, Physical files (tables), Logical files (views), Members in IBM AS/400 before an app can act on them. When that bridge is a nightly export or a hand-run CSV, every downstream system spends the day working from a roster that has already moved on.

Stacksync syncs Libraries, Physical files (tables), Logical files (views), Members in IBM AS/400 with Onboarding, Deductions (Pay Setup), Earnings (Pay Setup), Local and State Taxes in Paylocity field by field, in real time. You decide which system owns which fields — Paylocity typically owns identity and org attributes, while operational or computed values can flow back the other way — and Stacksync keeps every copy consistent, matching records on a stable key and resolving conflicts by rules you set.

The result is one live picture of the workforce on both sides: HR keeps its source of truth, and the database keeps a current mirror that internal apps, reports, and access controls can trust without a batch window in between.

Common use cases

  • 01 Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.
  • 02 Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.
  • 03 Upsert recurring Deductions and Earnings on employee records when benefits or 401(k) elections change in a benefits admin system, without re-keying payroll setup.
  • 04 Read Pay Statements and Direct Deposit allocations into a Postgres or warehouse database for labor-cost, GL, and headcount reporting in SQL.

Common sync patterns

One directory of record

When a person record is added, changed, or deactivated in either system, the matching row in the other stays current, ending dual maintenance.

Reporting and analytics on current data

Onboarding, Deductions (Pay Setup), Earnings (Pay Setup), Local and State Taxes replicate into IBM AS/400 where they join operational tables, so headcount, roles, and status reports run on the live state without manual pulls.

Org and structure stay aligned

Groups, departments, managers, and reporting lines from Paylocity stay consistent in IBM AS/400, so hierarchy-driven logic and permissions don't drift.

What you can sync between IBM AS/400 and Paylocity

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.

IBM AS/400 objects Paylocity objects How this pairing syncs
Journals and journal receivers The change log that enables log-based CDC on journaled files. Deductions (Pay Setup) Recurring deduction codes at the employee level; two-way via Upsert Deduction and Delete, with Get Deduction / Get All Deductions for reads. Journals and journal receivers is specific to IBM AS/400 and Deductions (Pay Setup) to Paylocity — each maps to any object or custom field on the other side.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Earnings (Pay Setup) Recurring earning codes at the employee level; two-way via Upsert Earning and Delete, with Get All Earnings and Get by earning code for reads. Data queues is specific to IBM AS/400 and Earnings (Pay Setup) to Paylocity — each maps to any object or custom field on the other side.
Libraries The schema-equivalent containers that scope which files a sync reads. Local and State Taxes Two-way via Create/Update/Delete Local Tax and Upsert Primary / Non-Primary State Tax; Get by tax code and Get All for reads. Libraries is specific to IBM AS/400 and Local and State Taxes to Paylocity — each maps to any object or custom field on the other side.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Direct Deposit Read-only: Get All Direct Deposit and Get Employee Bank Accounts return main and additional allocations. Bank details cannot be written through the API. Physical files (tables) is specific to IBM AS/400 and Direct Deposit to Paylocity — each maps to any object or custom field on the other side.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Pay Statements Read-only detailed payroll statement data — earnings, deductions, taxes, and direct deposit allocations by year, check date, or date range. Pulled for reporting, never written. Logical files (views) is specific to IBM AS/400 and Pay Statements to Paylocity — each maps to any object or custom field on the other side.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Company Codes Read-only reference codes and descriptions (cost centers, departments, positions) used to validate field mappings on employee writes. Members is specific to IBM AS/400 and Company Codes to Paylocity — each maps to any object or custom field on the other side.

How changes propagate between IBM AS/400 and Paylocity

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.

IBM AS/400 Paylocity Sub-second propagation

DetectionChanges in IBM AS/400 are captured at the source via change data capture — no polling loop against its API. Journal-based CDC by reading journal receivers on journaled files.

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

Paylocity IBM AS/400 Sub-second propagation

DetectionPaylocity notifies Stacksync of record changes through webhook events. Webhooks — Paylocity POSTs Employee New Hire, Employee Change, Termination, Payroll Processed, and Time Off Approval events to a callback URL.

DeliveryEach detected change is applied to IBM AS/400 as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.
  • Paylocity: 25 requests per second (1,500 per minute); exceeding it returns HTTP 429. Every path is scoped to a Paylocity-assigned companyId (a company code, not a UUID).

Integration surface
SQL over JDBC/ODBC to Db2 for i (for example the JTOpen/jt400 driver), alongside native record-level access
Authentication
IBM i user profile credentials (database credentials)

Paylocity

Integration surface
REST API (v1 and v2), JSON payloads
Authentication
OAuth 2.0 client credentials via the Paylocity Identity Provider (/IdentityServer/connect/token) with the WebLinkAPI scope; access tokens expire after one hour and API access must be enabled by Paylocity for the company
Change detection
Webhooks — Paylocity POSTs Employee New Hire, Employee Change, Termination, Payroll Processed, and Time Off Approval events to a callback URL; payloads carry only companyId and employeeId, so the receiver calls the relevant API to fetch changed values. Scheduled polling is used for objects without webhooks.
