This article, part of our in-depth [**HRIS API series**](/blog/full-list-of-knits-hris-api-guides/), focuses on how to **fetch employee and accounting data using Payfit’s API**. ### Prerequisites Before making requests to Payfit’s API, ensure you have: - Access to Payfit’s Partner API with valid credentials. - The **Company ID** for which you want to retrieve data. - A **Python environment** set up with libraries like `requests`. ### API Endpoints The following Payfit endpoints are typically used for accessing company and employee-level data: - **Company Information:** `GET https://partner-api.payfit.com/companies/{companyId}` - **Accounting Data:** `GET https://partner-api.payfit.com/companies/{companyId}/accounting-v2` ### Step-by-Step Implementation #### Step 1: Fetch Company Information ``` import requests def get_company_info(company_id, headers): url = f"https://partner-api.payfit.com/companies/{company_id}" response = requests.get(url, headers=headers) return response.json() ``` #### Step 2: Fetch Employee Accounting Data ``` def get_employee_accounting_data(company_id, date, headers): url = f"https://partner-api.payfit.com/companies/{company_id}/accounting-v2" params = {"date": date} response = requests.get(url, headers=headers, params=params) return response.json() ``` **Note:** The `date` parameter should follow the format `YYYYMM` (e.g., `202212` for December 2022). ### Common Pitfalls to Avoid 1. **Incorrect endpoint usage:** Always verify you’re using the latest Payfit API version. 2. **Authentication errors:** Missing or invalid tokens can lead to 401 Unauthorized errors. 3. **Ignoring rate limits:** Payfit enforces rate limits add retry logic with exponential backoff. 4. **Invalid date formats:** Ensure dates follow the correct `YYYYMM` format. 5. **Not validating company IDs:** Invalid IDs can cause 404 or empty responses. 6. **Poor error handling:** Always check response codes and handle failures gracefully. ### Frequently Asked Questions **1. What authentication method does Payfit API use?** Typically OAuth or API key-based authentication, depending on your access level. **2. How can I handle API rate limits?** Use retry logic with exponential backoff and respect the `Retry-After` header. **3. What is the correct date format for accounting data?** Use `YYYYMM`, e.g., `202401` for January 2024. **4. Can I retrieve data for multiple months in one call?** No, each API request fetches data for a single month. **5. What if I get a 401 Unauthorized error?** Double-check your API token and ensure it hasn’t expired. **6. How should I handle response errors?** Implement robust error handling based on HTTP status codes (e.g., 400, 401, 429, 500). ### Why Use Knit for Payfit API Integration Integrating directly with Payfit can be time-consuming, especially with complex authentication and version updates. **Knit** simplifies this by offering a **single, unified API** to access Payfit and other HRIS systems with built-in: - Authentication and authorization handling - Continuous integration maintenance - Unified data models for employees, payroll, and accounting By integrating with [Knit](https://developers.getknit.dev/reference/hris-apps) once, your team can connect to Payfit and dozens of other systems effortlessly saving engineering hours and reducing maintenance overhead. --- **Ready to build this integration?** Explore Knit’s [Payfit integration](/integration/payfit/) or read more about our [Unified HRIS API](/integration-categories/unified-hris-api/). ![](https://storage.googleapis.com/knit-website-media/2026/08/64c34ca1e0546a9d333bb35a_Kunal-3-150x150.png)Written by Kunal Mishra Changing integration landscape, one organization at a time‍ Keep Reading ------------ ![](https://storage.googleapis.com/knit-website-media/2026/08/blog-banner-green-640x400.png) [Tutorials](https://lb.getknit.dev/blogs/tutorials/) ### [How to Create a Slack Bot in 5 Minutes: A to Z Guide](https://lb.getknit.dev/blog/how-to-create-a-slack-bot/) You can create your own Slack Bot in just a few minutes with the Knit Unified API.
