Third-party integration in PeopleSoft

-

Third-party integration in PeopleSoft refers to the process of connecting PeopleSoft applications (like HR, Finance, or Supply Chain) with external systems or services, such as payroll vendors, banks, tax authorities, or custom web applications. PeopleSoft offers several built-in tools and technologies to facilitate this kind of integration, depending on the use case, data format, and real-time vs batch requirements.

Here’s a breakdown of how third-party integration typically works in PeopleSoft:

🔧 Common Integration Methods

1. Integration Broker (IB)

  • Purpose: Real-time or near real-time integrations using messages and services.

  • Technologies Used: SOAP, REST, HTTP, XML, JSON.

  • Components:

    • Service operations (define messages and routing)

    • Nodes (represent external systems)

    • Queues (manage message delivery)

  • Example: Sending employee data to a benefits provider in real time.

2. Component Interfaces (CI)

  • Purpose: Provide programmatic access to PeopleSoft components (like employee data entry).

  • Used by: Java, COM clients, or via PeopleCode.

  • Example: A third-party application updating job data through a CI.

3. File-Based Interfaces (Flat Files / CSV)

  • Purpose: Batch data exchange.

  • Tools Used: SFTP, File Layouts, Application Engine.

  • Example: Receiving payroll data in a CSV file and loading it into PeopleSoft tables.

4. Web Services (SOAP/REST)

  • Purpose: Expose or consume services over the web.

  • Built Using: Integration Broker, RESTful APIs, WSDLs.

  • Example: A mobile app consuming REST APIs to retrieve leave balances.

5. Application Messaging

  • Purpose: Publish/subscribe model for loosely coupled integrations.

  • Built On: Integration Broker.

  • Example: Automatically notifying an external travel system when an employee is hired.

6. Database Level Integration

  • Purpose: Direct access to PeopleSoft database (least recommended due to maintenance risks).

  • Tools Used: ETL tools like Informatica, stored procedures, views.

  • Example: A data warehouse pulls data directly from PeopleSoft tables.

🔁 Inbound vs Outbound

  • Inbound Integration: Data is coming into PeopleSoft (e.g., time entries from a biometric device).

  • Outbound Integration: Data is sent from PeopleSoft (e.g., vendor payments to a bank).

🔐 Security Considerations

  • Authentication (Basic Auth, OAuth, certificates)

  • Authorization via roles/permissions

  • Encryption (SSL/TLS, PGP for files)

✅ Best Practices

  • Use Integration Broker for scalability and maintenance.

  • Use Service Operations with versioning for compatibility.

  • Implement error handling, logging, and monitoring.

  • Avoid direct DB integrations unless absolutely necessary.

Application Classes in PeopleSoft Defining and Importing packages or classes in PeopleCode <Pacakge name>:<Subpacakge name>:<…>:<Class name or wild card> Class Extensions represents the “is-a” relationship.   When a class extends another class, it’s called a subclass of that class. No Multiple inheritances or Concept of interface in Application classes. Instance variables in the class are accessible in all the objects of that class. Application programs generally pass parameters by value, which is not the same as for existing functions. Parameter passing with object data types is by reference. When the objects are passed to method and it reassign the object with new object it will not reflected in the calling method. Application Programs use the out specifier to pass a parameter by reference. Method increment (&Value as number out); rem passed by reference.   Create is the key word used to create the class object.  ...
