Why teams connect Coupa and Ukg Pro

Keep the employee, department, and cost records that Coupa and Ukg Pro share consistent in real time, so the finance system and the people system stop drifting apart.

Coupa runs the money side of the company: who gets paid, what it costs, and which part of the business the cost belongs to. Ukg Pro runs the people side: who works here, which team they sit in, and how their employment changes over time. The two overlap on the same people and the same org structure, because every employee is also a payee and every department is also a cost center. When that overlap is maintained by hand, a new hire, a transfer, or a termination has to be keyed twice, and the two systems start to disagree about who is active and where the cost lands.

Stacksync syncs Expense Reports, Requisitions, Purchase Orders, Invoices in Coupa with Terminations, Configuration Setup (Code Tables), Time & Attendance (UTA), Employee (Person Details) in Ukg Pro bi-directionally and in real time. A person added, updated, or deactivated on either side appears on the other within seconds, with field-level mapping and conflict resolution in place of CSV exports and nightly batch jobs.

That matters most when money follows a people event. A hire that finance can pay, a leaver whose access ends, a transfer that redirects cost to the right team, all happen from one change instead of two, so headcount and spend reconcile from the same set of records.

Common use cases

  • 01 Mirror Purchase Orders and their status into an operational Postgres database for spend reporting and three-way match analytics.
  • 02 Export approved Invoices and their lines from Coupa into an accounting/ERP system to drive the AP pay cycle and GL posting.
  • 03 Replicate Compensation and pay-statement / earnings history into a warehouse for headcount, labor-cost, and payroll reporting without manual BI exports.
  • 04 Deprovision accounts by subscribing to UKG Pro termination and job-change webhook events to disable IdP and app access as changes become effective.

Common sync patterns

One employee identity

A person's name, ID, or contact details corrected in either system update the other, so finance and HR reference the same person instead of maintaining two versions.

Department and cost-center alignment

The org structure maintained in Ukg Pro keeps the departments or cost centers in Coupa current, so spend and headcount roll up the same way.

Status changes propagate

A role, department, or employment-status change in either system updates the other within seconds, so cost allocation, access, and reporting reflect the current state.

What you can sync between Coupa and Ukg Pro

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.

Coupa objects Ukg Pro objects How this pairing syncs
Expense Reports Employee expense reports and their lines; exported to AP or ERP for reimbursement and GL posting. Time & Attendance (UTA) Timekeeping and worked-hours data exposed by the UTA services; synced into scheduling, payroll, or workforce-analytics databases. Expense Reports is specific to Coupa and Time & Attendance (UTA) to Ukg Pro — each maps to any object or custom field on the other side.
Requisitions Employee purchase requests with lines and approval chains; read out to warehouses, or created via the API from upstream intake tools. Employee (Person Details) Core worker record with demographics and identifiers; read by listing employee IDs then fetching each profile, and created on hire via the personnel/onboarding endpoints. Requisitions is specific to Coupa and Employee (Person Details) to Ukg Pro — each maps to any object or custom field on the other side.
Purchase Orders PO headers and lines; synced two-way with ERPs so orders raised in Coupa flow to the ledger and status updates flow back on the /purchase_orders resource. Employment Details Employment status, hire and service dates, and company assignment; the record that drives active/terminated state for provisioning downstream. Purchase Orders is specific to Coupa and Employment Details to Ukg Pro — each maps to any object or custom field on the other side.
Invoices Supplier/AP invoices with lines and approval status; polled out to accounting and ERP systems for the pay cycle, or created through the API. Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. Invoices is specific to Coupa and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side.
Suppliers Supplier master records; kept aligned with an ERP vendor master and onboarding tools, synced two-way on the /suppliers resource. Compensation Details Effective-dated pay rate and salary; usually read into a warehouse for comp reporting and writable as new dated changes through the compensation endpoints. Suppliers is specific to Coupa and Compensation Details to Ukg Pro — each maps to any object or custom field on the other side.
Users Employee and user accounts with roles and content groups; provisioned and updated from an HRIS or identity provider. Payroll (Pay Statements, Direct Deposit, Earnings) Pay statements, direct-deposit accounts, and earnings history; read-only pay data replicated into finance and warehouse systems for labor-cost reporting. Users is specific to Coupa and Payroll (Pay Statements, Direct Deposit, Earnings) to Ukg Pro — each maps to any object or custom field on the other side.

How changes propagate between Coupa and Ukg Pro

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.

Coupa Ukg Pro Interval-based propagation

DetectionStacksync polls Coupa for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at and created-at filters (e.g.

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

Ukg Pro Coupa Sub-second propagation

DetectionUkg Pro notifies Stacksync of record changes through webhook events. No CDC stream.

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

Rate-limit considerations

  • Coupa: Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.
  • Ukg Pro: An API gateway throttles calls per client over a rolling window (typically per minute); UKG does not publish exact numeric thresholds. Exceeding the limit returns HTTP 429, and UKG recommends a roughly one-second looping backoff before resuming (a Retry-After header is not yet standard). Reads are offset-paginated.

How the Coupa and Ukg Pro connectors work

Coupa

Integration surface
REST Core API (JSON or XML)
Authentication
OAuth 2.0 / OIDC via the client-credentials grant; scopes take the service.object.right form (e.g. core.accounting.read, core.accounting.write). Legacy API keys are being retired (no new keys since R34; API-key auth unsupported from R36). Access tokens last 24 hours.
Change detection
Polling on updated-at and created-at filters (e.g. updated-at[gt]=<timestamp>); Coupa has no native webhook subscriptions, though admins can configure outbound Call Out / external notifications.
Capabilities

Rate limits
Coupa does not publish explicit rate limits or expose X-RateLimit/Retry-After headers; integrations page 50 records at a time and back off on 429/503 responses.

Ukg Pro

Integration surface
REST API (UKG Pro HCM REST services) with separate Onboarding and Recruiting REST APIs, plus legacy SOAP-based UKG Pro Web Services
Authentication
Core HCM REST APIs use HTTP Basic authentication with a dedicated web service account, plus a Customer API Key and a User API Key sent as headers (found under System Configuration > Security > Service Account Administration); the Onboarding and Recruiting REST APIs instead require a bearer Authorization Token from the token endpoint.
Change detection
No CDC stream. UKG Pro publishes Pro HCM Webhook Events for changes such as new hire, employee and job detail changes, termination, and PTO, which Stacksync subscribes to for near-real-time triggers; bulk and historical loads use paged reads with each service's modified-since filters.
Capabilities

Rate limits
An API gateway throttles calls per client over a rolling window (typically per minute); UKG does not publish exact numeric thresholds. Exceeding the limit returns HTTP 429, and UKG recommends a roughly one-second looping backoff before resuming (a Retry-After header is not yet standard). Reads are offset-paginated.
