In this post, we’ll focus on how to **retrieve employee data from the Lucca HR API**, a core functionality for HR teams looking to automate employee records, reporting, and analytics. If you’re looking for other use cases, such as authentication, rate limits, or advanced integrations, check out our full [**Lucca HR API Guide**](/integration/lucca-hr/). ### Getting Employee Data from Lucca HR API #### Prerequisites Before you start, make sure you have: - Access to the **Lucca HR API** with valid credentials. - A Python environment set up with the necessary libraries, such as `requests`. #### Key API Endpoints - `GET /api/v3/users`: Retrieve all active users. - `GET /api/v3/users?formerEmployees=true`: Retrieve all users, including terminated ones. - `GET /api/v3/users/{id}`: Retrieve data for a specific user by ID. ### Step-by-Step Process #### 1. Retrieve All Employees ``` import requests url = "https://your-lucca-instance/api/v3/users" headers = {"Authorization": "Bearer YOUR_ACCESS_TOKEN"} response = requests.get(url, headers=headers) all_users = response.json() print(all_users) ``` #### 2. Retrieve a Specific Employee ``` import requests user_id = "123" # Replace with the actual user ID url = f"https://your-lucca-instance/api/v3/users/{user_id}" headers = {"Authorization": "Bearer YOUR_ACCESS_TOKEN"} response = requests.get(url, headers=headers) user_data = response.json() print(user_data) ``` ### Common Pitfalls to Avoid Even seasoned developers can run into issues. Here are the most common mistakes when integrating with Lucca HR: 1. Using unsecured (non-HTTPS) endpoints for API calls. 2. Forgetting to include the required authentication header. 3. Calling incorrect or outdated API URLs. 4. Failing to handle HTTP errors and status codes. 5. Ignoring API rate limits, leading to throttling. 6. Not validating or sanitizing JSON responses. 7. Hardcoding sensitive credentials or API tokens in scripts. ### Frequently Asked Questions **1. How do I authenticate with the Lucca HR API?** Use a Bearer token in the Authorization header, for example: `Authorization: Bearer YOUR_ACCESS_TOKEN` **2. Can I filter users by specific criteria?** Yes. Use query parameters such as `firstName`, `lastName`, or `matricule` to filter results. **3. How do I update user information?** Use the `PUT /api/v3/users/{id}` endpoint with the updated data payload. **4. What format are responses in?** All responses are in **JSON** format. **5. Is there a limit to how many users I can retrieve at once?** Yes. The API uses pagination, check the documentation for details on `page` and `limit` parameters. **6. How do I handle API errors?** Inspect the HTTP status code and response body for detailed error messages. **7. Can I retrieve only specific fields from the user data?** Yes. You can use the `fields` parameter to limit your response to specific attributes. ### Knit for Lucca HR API Integration If you’re looking to skip the heavy lifting of building and maintaining direct integrations, **Knit API** offers a seamless alternative.
