### **Introduction**
This guide is part of our in-depth series on the [**HRIS API**](/integration-categories/unified-hris-api/)**.** In this edition, we will explore Kallidus API and its functionality, authentication mechanisms, and best practices. We’ll focus on one of the most common use cases, **retrieving employee data using the Kallidus API**.
### **Get Employee Data from Kallidus API**
#### **Prerequisites**
Before you begin, ensure that:
- You have access to the **Kallidus (Sapling) API key**, which can be generated from your Sapling Admin Settings.
- All requests are made using **HTTPS with TLS 1.2 or higher**.
- You know your company’s **subdomain**, which is required to construct the API endpoint.
#### **API Endpoints**
- **US Data Centers:** `https://{{subdomain}}.saplingapp.io/api/v1/beta/users`
- **UK Data Centers:** `https://{{subdomain}}.kallidus-suite.com/hr/api/v1/beta/users`
### **Step-by-Step Guide**
#### **1. Set Up Authentication**
```
import requests
headers = {'Authorization': 'Bearer YOUR_API_KEY'}
```
`
`
#### **2. Get Data for a Single Employee**
```
subdomain = 'your_subdomain'
employee_id = 'specific_employee_id'
url = f'https://{subdomain}.saplingapp.io/api/v1/beta/users/{employee_id}'
response = requests.get(url, headers=headers)
if response.status_code == 200:
employee_data = response.json()
print(employee_data)
else:
print('Error:', response.status_code)
```
`
`
#### **3. Get Data for All Employees**
```
url = f'https://{subdomain}.saplingapp.io/api/v1/beta/users'
response = requests.get(url, headers=headers)
if response.status_code == 200:
all_employees_data = response.json()
print(all_employees_data)
else:
print('Error:', response.status_code)
```
`
`
### **Common Pitfalls to Avoid**
1. **Invalid API Key:** Ensure your API key is active and correctly formatted in the Authorization header.
2. **Outdated TLS Version:** The API only supports TLS 1.2 and above.
3. **Incorrect Subdomain:** Replace `{{subdomain}}` with your actual company subdomain.
4. **Ignoring Pagination:** For large datasets, use pagination (`?page=` parameter) to avoid incomplete responses.
5. **Improper Error Handling:** Always check HTTP status codes and handle 4xx/5xx errors gracefully.
6. **Missing Fields:** Not all fields may be present, verify using the fields endpoint before assuming availability.
7. **Rate Limiting:** While Kallidus doesn’t strictly enforce rate limits, excessive requests may lead to throttling.
### **Frequently Asked Questions**
**1. How do I generate an API key for Kallidus?**
You can create an API key in your **Sapling Admin Settings** under API Configuration.
**2. What format does the API return data in?**
Responses are returned in **JSON format**.
**3. Is there a rate limit for requests?**
Currently, there’s no fixed limit, but Kallidus may throttle requests if traffic spikes.
**4. Can I access historical employee data?**
The API provides **current employee data**. To track changes over time, set up **webhooks**.
**5. What should I do if I receive a 401 Unauthorized error?**
Check that your API key is valid, properly included in the header, and not expired.
**6. How do I handle large employee datasets?**
Use **pagination** to retrieve data page by page and ensure you don’t miss any records.
**7. What happens if I exceed rate thresholds?**
Your requests might be **temporarily throttled**. Implement retry logic with exponential backoff.
### **Simplify Kallidus Integration with Knit**
Manually handling API integrations can be time-consuming and error-prone. With **Knit**, you can integrate with the **Kallidus API** effortlessly through a single, unified connection.
[Knit HRIS API](/integration-categories/unified-hris-api/) takes care of authentication and token refresh, data syncing and normalization as well as ongoing integration maintenance. This not only accelerates your development process but ensures **reliable, secure, and scalable** API connections.
