This is what “Get the Payroll Journal” would look like. Example request: ``` curl https://api.fous.com/v1/runs \ -H "Authorization: Bearer $FOUS_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "method": "myapps.paychex.com/get_payroll_journal", "input": { "date_from": "2026-10-26", "date_to": "2026-11-08", "employee": "All Employees" } }' ``` Example response: ``` { "status": "completed", "data": { "company": "Acme Supply Co", "checks": [ { "employee": "Employee 0042", "check_date": "2026-11-07", "pay_period": "2026-10-19 to 2026-11-01", "earnings": { "hourly": 2236 }, "employee_taxes": { "federal": 214.5, "fica": 171.05 }, "employer_taxes": { "fica": 171.05, "futa": 13.42 }, "deductions": { "401k": 111.8, "medical": 64 }, "net_pay": 1674.65 } ] } } ``` An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request. ## Paychex Flex’s own options Paychex has a public API with Company, Payroll, Worker, Webhooks and Management sections. A client can create its own app inside Paychex Flex if a user has permission to manage connected applications. Software vendors go through Paychex's partner process, and each client approves the connection in Integrated Apps. | Option | What it covers | What it takes | | --- | --- | --- | | API app created by a client | Paychex's public API for your own company, and for other client IDs linked to the app as Child accounts. | A Paychex Flex user allowed to manage connected applications, such as a Super Admin or a Security Admin. | | Partner application | The same API for a vendor serving many Paychex clients, with the endpoints requested for production. | A questionnaire, review by the Corporate Partnerships Team, a sandbox build, a demo, and each client's approval in Integrated Apps. | | Webhooks | Notifications to a registered app, such as CLT_ACCESS when a client accepts a partner integration. | A production app registered for the webhook. | | Paychex Flex by hand | Analytics & Reports, where reports such as the Payroll Journal are run for a date range and downloaded. | A Paychex Flex sign-in with access to the reports. | Read on November 12, 2026: [Paychex API Developer Center: process for clients](https://developer.paychex.com/client), [Paychex API Developer Center: process for partners](https://developer.paychex.com/partner), [Paychex API documentation](https://developer.paychex.com/documentation). ## Signing in to Paychex Flex Paychex Flex signs people in at login.flex.paychex.com, which asks for the username on its own first screen. With Fous, you sign in once through that page with your own Paychex Flex account. The login is sealed with AES-256 and never returned by the API or written to logs, and a method reads and does only what your account can. ## Worth knowing - **Who can create an API app**: Creating an app in Paychex Flex needs permission to manage connected applications, which roles such as Super Admin and Security Admin have. - **Several client IDs, one app**: Paychex suggests choosing one client account to manage the integration on, the Parent account, and linking other client accounts to the app as Child accounts. - **Vendors wait for client approval**: A partner sends Request Client Access with the client's 8-digit displayId. The client then signs in to Paychex Flex and selects Approve or Deny under Integrated Apps, one client at a time. - **The Payroll Journal takes two parameters**: The Payroll Journal under Analytics & Reports is run for a Date Range and an employee parameter. A full-year pull uses Current Year and All Employees. ## More in HR: payroll, hiring and screening - [The Work Number](https://fous.com/automate/the-work-number.md) - [Workday](https://fous.com/automate/workday.md) - [Indeed for Employers](https://fous.com/automate/indeed-for-employers.md) - [SEEK Employer](https://fous.com/automate/seek-employer.md) - [Paycom](https://fous.com/automate/paycom.md) - [Paylocity](https://fous.com/automate/paylocity.md) - [ADP Workforce Now](https://fous.com/automate/adp-workforce-now.md) - [Silae](https://fous.com/automate/silae.md) - [RUN Powered by ADP](https://fous.com/automate/run-powered-by-adp.md) - [Gusto](https://fous.com/automate/gusto.md) Other industries: [SOKA-BAU Online-Service](/automate/soka-bau-online-service), [NuORDER](/automate/nuorder), [Walmart Seller Center](/automate/walmart-seller-center), [AQA Centre Services](/automate/aqa-centre-services), [DTE Energy online account](/automate/dte-energy-online-account), [METRO Online-Kundenkonto](/automate/metro-online-kundenkonto). ## Frequently asked questions ### Does Paychex Flex have an API? Yes. Paychex publishes an API with Company, Payroll, Worker, Webhooks and Management sections. A client user who can manage connected applications creates an app in Paychex Flex, and vendors apply through Paychex's partner process, with each client approving in Integrated Apps. ### Can an accountant reach several Paychex clients through one app? Through Paychex's own API, yes, in two ways: a client app can link other client IDs as Child accounts, and an approved partner app is linked to each client after that client approves it in Integrated Apps. ### Where is the Payroll Journal in Paychex Flex? Under Analytics & Reports, then View All Reports, then Payroll Journal. You set the Date Range and the employee parameter, run the report and download it. ### How does a partner app get access to a client? The partner calls Request Client Access with the client's 8-digit displayId, which puts the app in that client's Integrated Apps. The client signs in to Paychex Flex and approves or denies it there, and the partner can listen for the CLT_ACCESS webhook. ### Is Fous affiliated with Paychex? No. Fous is an independent product. It works through your own Paychex Flex account, and a method reads and does only what that account can.
