Retrieve processed Paylocity payroll pay-statement data via the PayStatements API and aggregate it into a general ledger journal for posting to an ERP system.

Steps

1. Authenticate to the Paylocity API using the OAuth 2.0 client credentials grant to obtain an access token.
2. Call the Lookup/List Values and Employee Earnings and Deductions endpoints to build a mapping of every earning and deduction code used in payroll to your GL chart of accounts.
3. Call GET /api/v2/companies/{companyId}/employees/{employeeId}/paystatement/summary/{year} (or the /{year}/{checkDate} variant) per employee, or GET /apihub/payrollhistory/v1/companies/{companyId}/employees/{employeeId}/paystatements for a date range, to retrieve check-run summary and line-item earnings/deductions/taxes.
4. Aggregate the per-employee earnings, deductions, and tax line items by mapped GL code (and department/cost center if needed) to construct journal entries yourself, since Paylocity returns pay statement data, not a pre-built GL file.
5. Subscribe to Payroll Processed Webhooks so your integration is triggered automatically once a payroll run completes, rather than polling.
6. Post the resulting journal entries to the target accounting system.
