Sync Paychex data

BankInfo

The BankInfo object is used to represent the Bank Account information for an Employee.

Benefit

The Benefit object is used to represent a benefit that an employee has enrolled in.

Company

The Company object is used to represent a company within the HRIS / Payroll system.

Employee

The Employee object is used to represent any person who has been employed by a company. By default, it returns all employees. To filter for only active employees, set the employment_status query parameter to ACTIVE.

EmployeePayrollRun

The EmployeePayrollRun object is used to represent an employee's pay statement for a specific payroll run.

EmployerBenefit

The Employer Benefit object is used to represent a benefit plan offered by a company.

Employment

The Employment object is used to represent a job position at a company. If an integration supports historical tracking of employments, it will be reflected in the data. If not, a new Employment object will be created whenever there is a change in job title or pay. The effective_date field should be used to order Employment objects, with the most recent date corresponding to the latest employment record for an employee.

Group

The Group object is used to represent any subset of employees across, for example, DEPARTMENT or TEAM. Employees can be in multiple Groups.

Location

The Location object is used to represent an address that can be associated with an employee.

PayrollRun

The PayrollRun object is used to represent a group of pay statements for a specific pay schedule.

Team

The Team object is used to represent a subdivision of the company, usually a department. Each employee will be grouped into one specific Team.

FAQ on integrating with Paychex API

What types of Paychex data can I retrieve through Merge's API?

You can access comprehensive HR data, including employee records, payroll information, benefits details, direct deposit (banking) information, and more. This data is also normalized into Merge's standardized Common Models, allowing you to access and manage Paychex data seamlessly across different HRIS integrations.

Learn more about the Paychex data you can access via Merge.

How does Merge normalize Paychex data fields?

Merge normalizes Paychex data by converting it into standard data models that are consistent across other HRIS platforms supported by Merge. This process allows you to work with Paychex data in a format that's compatible with other HR systems and simplifies multi-platform data handling.

How frequently does Merge sync data from Paychex?

Merge provides flexible sync frequencies. And while they vary based on the Common Model and frequency you set (Highest, High, Standard, and Daily), they’re typically every hour, 3 hours, 6 hours, or 24 hours.

You can also sync data outside of these intervals via Merge’s Force Resync endpoint, and you can sync data in real-time by using Merge’s Automatic Webhooks feature.

How can I check when Paychex data was last synced?

You can monitor the last sync status for Paychex data directly within the Merge Dashboard. This feature allows you to view the most recent sync timestamp, ensuring visibility into data freshness and the timing of the last update

In case the issue lies on your customer’s end, Merge will diagnose the issue and provide the appropriate remediation steps, enabling your customer success team to work with the affected client on resolving the issue quickly.

Meta endpoint

Programmatically access required schemas

Third-party providers require specific (and often different) fields to write data to their APIs, making your code a mess.

Dynamically fetch required data schemas from Merge’s /meta endpoint to make POST or PATCH requests that just work.
