# Multiplier’s integration with Workday Via API

Multiplier smoothly integrates with Workday, centralizing employee information for efficient and accurate payroll management. While Workday offers PECI Integration, Multiplier enhances this process through API integration.

## Understanding PECI and API

* PECI (Payroll Effective Change Interface), introduced by Workday in 2016, sequentially transmits payroll changes for each worker, including effective and data entry dates.
* API (Application Programming Interface) enables two-way communication between your system and the payroll system, allowing faster data requests and tailored data synchronization.

## Why Choose Multiplier's API Integration over Workday's PECI?

| Feature       | PECI (SFTP)                                                                             | API                                                                       |
| ------------- | --------------------------------------------------------------------------------------- | ------------------------------------------------------------------------- |
| Communication | One-way: Workday sends a file (XML) to the payroll partner.                             | Two-way: Enables faster data exchange and requests.                       |
| Setup         | Requires initial setup, including field selection, sync frequency, and data filters.    | Simple setup: Share the API key, and grant permissions within Workday.    |
| Flexibility   | Changes require contacting the payroll partner, leading to potential delays.            | The payroll vendor handles changes without client intervention.           |
| Data Flow     | One-way outbound: Information cannot be sent back to Workday.                           | Two-way: Data, such as payslips, can be written back to Workday.          |
| Data Sync     | Periodic sync is based on Workday settings; manual sync requires initiation in Workday. | Manual sync can be triggered from the Multiplier platform.                |
| Data Updates  | Provides all changes between syncs, potentially including irrelevant information.       | Provides only the latest change between syncs, focusing on relevant data. |

## Key Advantages of API Integration

* Effortless Setup: Supported by Multiplier, requiring no additional development effort.
* Faster Data Sync: Supports higher frequency compared to PECI.
* Simplified Setup and Security: Easily set up API support in Workday, with security managed by Workday.

## Conclusion

Multiplier's API integration with Workday simplifies payroll management by streamlining data exchange, enhancing flexibility, and ensuring data accuracy. This user-friendly approach saves time and effort, allowing you to focus on core business operations.
