### Introduction
This article is part of our in-depth series on the **HRIS API**. In this guide, we’ll walk through how to **retrieve employee data** from IRIS Cascade, covering endpoints, prerequisites, sample code, and common troubleshooting tips.
If you’d like a deeper look at authentication, rate limits, and other use cases, check out our full list of [HRIS API Guides](/blog/full-list-of-knits-hris-api-guides/).
The **IRIS Cascade API** provides endpoints that let you retrieve detailed employee information from basic personal details to department, position, and status. You can query data for a **single employee** or retrieve **all employee records** in bulk.
### Prerequisites
Before you begin, make sure you have:
- Access to the **IRIS Cascade API** with valid credentials.
- A **Python** environment with the `requests` library installed.
- Proper authorization tokens (usually a Bearer token).
### API Endpoints
- **Get all employees:** `GET /employees`
- **Get a specific employee by ID:** `GET /employees/{id}`
### Step-by-Step Guide
#### 1. Retrieve All Employees
```
import requests
url = "https://yourdomain.com/api/employees"
headers = {"Authorization": "Bearer YOUR_ACCESS_TOKEN"}
response = requests.get(url, headers=headers)
if response.status_code == 200:
employees = response.json()
print(employees)
else:
print("Failed to retrieve employees")
```
`
`
#### 2. Retrieve a Single Employee by ID
```
import requests
employee_id = "12345"
url = f"https://yourdomain.com/api/employees/{employee_id}"
headers = {"Authorization": "Bearer YOUR_ACCESS_TOKEN"}
response = requests.get(url, headers=headers)
if response.status_code == 200:
employee = response.json()
print(employee)
else:
print("Failed to retrieve employee")
```
`
`
### Common Pitfalls and How to Avoid Them
1. **Incorrect endpoint URL:** Double-check your base URL and path before sending a request.
2. **Expired or invalid tokens:** Refresh your token regularly or implement automated token rotation.
3. **Ignoring pagination:** Large datasets are often paginated; use `$top` and `$skip` parameters.
4. **Uncaught errors:** Always handle `4xx` and `5xx` responses to log and debug effectively.
5. **Rate limit breaches:** Respect API rate limits and add retry mechanisms.
6. **Incorrect employee ID format:** Ensure IDs match the expected format defined by your HR system.
7. **SSL or network errors:** Configure secure connections and handle connection exceptions gracefully.
### Frequently Asked Questions
**1. What is the maximum number of employees I can retrieve in one request?**
You can fetch up to **250 employees** per request using the `$top` query parameter.
**2. How can I handle pagination for large datasets?**
Use `$skip` and `$top` parameters to iterate through the employee list efficiently.
**3. Can I filter the employee data?**
Yes, apply the `$filter` parameter to retrieve employees based on specific attributes like department or job title.
**4. What data formats does IRIS Cascade support?**
The API supports **JSON** and **XML** response formats. JSON is recommended for most integrations.
**5. How do I authenticate my API requests?**
Include a **Bearer token** in the `Authorization` header of every request.
**6. What if I receive a 401 Unauthorized error?**
This usually means your token has expired or is invalid. Generate a new one and try again.
### Integrating IRIS Cascade with Knit
Instead of building and maintaining your own integration, **Knit API** lets you connect to IRIS Cascade in minutes. With a single integration, Knit manages:
- Authentication and token refresh
- Data synchronization
- Error handling and maintenance
For developers who want to avoid maintaining HR integrations and focus on product innovation, [**Knit** ](/integration-categories/unified-hris-api/)provides a unified, reliable, and scalable way to connect to IRIS Cascade and other HRIS systems effortlessly.
