Why teams connect MotherDuck and Paylocity

Land the people and organization records from Paylocity in MotherDuck as live tables for workforce reporting, without extract jobs, and write computed results back where Paylocity can use them.

Workforce data is some of the most requested data in the warehouse and some of the most awkward to move: the record types are many, the fields carry sensitive personal information, the APIs are strict, and hand-built extract jobs go stale or break quietly. Whether Paylocity is the system of record for employees and payroll, for candidates and applications, or for learners and course completions, the reporting belongs in MotherDuck next to everything else the company measures.

Stacksync syncs Onboarding, Deductions (Pay Setup), Earnings (Pay Setup), Local and State Taxes from Paylocity into tables in MotherDuck continuously, handling API limits and schema drift as they come. The connection is bi-directional, so values computed in MotherDuck, such as headcount rollups, cost allocations, or attrition risk flags, can be written back to fields in Paylocity where the HR team acts on them. You configure which records and fields cross over, and in which direction, instead of maintaining pipeline code.

Common use cases

  • 01 Sync modeled MotherDuck tables outward to operational tools for activation
  • 02 Share curated, synced datasets with other teams through read-only database shares
  • 03 Read Pay Statements and Direct Deposit allocations into a Postgres or warehouse database for labor-cost, GL, and headcount reporting in SQL.
  • 04 React to the Employee Change webhook to pull the updated Employee record and propagate title, location, or manager changes to downstream apps within minutes.

Common sync patterns

Queryable history for planning and audit

A continuously synced copy in MotherDuck gives you a durable, queryable record of how Paylocity's records change over time, for headcount planning and audit questions.

Write-back of computed values

Segments, rollups, or risk flags computed in MotherDuck sync back onto the matching records in Paylocity, where the HR team sees them in the system they already use.

HR data in the warehouse, minus the pipeline

People and organization records from Paylocity arrive in MotherDuck as queryable tables, current within seconds instead of a day behind, replacing hand-built extract jobs.

What you can sync between MotherDuck 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.

MotherDuck objects Paylocity objects How this pairing syncs
Database Shares Read-only copies of a database shared with other users or teams. Custom Fields Read-only company-specific custom fields returned by category, used to enrich the employee record downstream. Database Shares is specific to MotherDuck and Custom Fields to Paylocity — each maps to any object or custom field on the other side.
Attached Local DuckDB Databases Local files attached alongside cloud databases for hybrid queries. Employees Core HR record keyed by companyId + employeeId; two-way via Create New Employee (POST) and Update Employee (PATCH), plus Get Employee / Get All Employees for reads. Attached Local DuckDB Databases is specific to MotherDuck and Employees to Paylocity — each maps to any object or custom field on the other side.
Databases Cloud-hosted DuckDB databases that scope a sync's reads and writes. Onboarding Create Employee Onboarding pushes new-hire data into Paylocity's onboarding workflow; Get Onboarding Status reads back partner onboarding progress. Write-in for hires from an ATS. Databases is specific to MotherDuck and Onboarding to Paylocity — each maps to any object or custom field on the other side.
Schemas Namespaces within a database used to organize synced tables. 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. Schemas is specific to MotherDuck and Deductions (Pay Setup) to Paylocity — each maps to any object or custom field on the other side.
Tables The main landing target for synced records and source for analysis. 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. Tables is specific to MotherDuck and Earnings (Pay Setup) to Paylocity — each maps to any object or custom field on the other side.

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. Views is specific to MotherDuck and Local and State Taxes to Paylocity — each maps to any object or custom field on the other side.

How changes propagate between MotherDuck 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.

MotherDuck Paylocity Interval-based propagation

DetectionStacksync polls MotherDuck for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

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

Paylocity MotherDuck 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 MotherDuck as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • MotherDuck: Subject to the platform's compute and concurrency limits rather than per-request API rate limits.
  • 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).

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.
