This DIY Developer Guide for Infor explains how to build secure, scalable, and reliable custom integrations. Infor provides a variety of ERP platforms (Infor CloudSuite, Infor LN, Infor M3) with powerful RESTful APIs and ION middleware that support seamless integration with CRMs, eCommerce platforms, supply chain management tools, and financial systems.

Whether you’re syncing inventory, automating procurement, or integrating customer orders, mastering Infor integrations enhances business automation and operational agility.

Prerequisites for Infor Integrations

• Access to an Infor ERP environment (CloudSuite, LN, M3)
• API Gateway URL and credentials
• Familiarity with:
  • REST APIs and OData
  • JSON payload structures
  • OAuth 2.0 Authentication
• Tools: Postman, Infor API Gateway documentation, ION Desk for middleware management

Step 1: Authentication for Infor Integrations

Infor uses OAuth 2.0 for secure API authentication.

OAuth 2.0 Token Request Example:

POST https://{infor-server}/IDP/connect/token
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials&client_id=YourClientID&client_secret=YourClientSecret&scope=api

The Access Token received is used in the Authorization header for subsequent API calls.

Step 2: Endpoint Discovery and Data Mapping for Infor Integrations

Common API Resources:

• Customers and Vendors
• Sales Orders and Purchase Orders
• Items and Inventory
• Invoices and Payments
• Supply Chain Activities

Process:

• Refer to Infor API documentation to explore available endpoints.
• Map external system fields precisely to Infor business objects.

Important considerations:

• Required vs. optional fields
• Handling data relationships (e.g., linking Orders to Customers)
• Proper formatting for dates, currencies, and IDs

Step 3: Building Integration Flows for Infor

Integration Patterns:

• Inbound (to Infor): POST and PATCH for record creation and updates
• Outbound (from Infor): GET to retrieve records or reports

Example: Creating a Sales Order:

POST /api/v2/SalesOrders
{
  "Customer": "CUST100",
  "OrderDate": "2025-05-01",
  "Lines": [
    {
      "Item": "ITEM100",
      "Quantity": 5,
      "Price": 100.00
    }
  ]
}

Example: Retrieving Inventory:

GET /api/v2/InventoryItems?$filter=OnHand gt 0

Step 4: Error Handling and Pagination for Infor Integrations

Error Handling:

• Capture HTTP error codes and detailed Infor-specific error messages.
• Implement retry logic for temporary errors like 429 (Too Many Requests).

Pagination:

• Use $top and $skip for paging through large datasets.

Example:

GET /api/v2/Customers?$top=50&$skip=50

Step 5: Testing and Validation for Infor Integrations

• Validate authentication and endpoint access with Postman.
• Test data payloads for record creation and updates.
• Perform volume and load testing to verify scalability.

Step 6: Deployment and Security of Infor Integrations

• Deploy integrations on secure infrastructure (AWS, Azure, private cloud)
• Store client secrets and tokens securely in Key Vaults
• Enforce HTTPS/TLS for all API communications
• Enable comprehensive logging and role-based access controls

Step 7: Maintenance and Monitoring for Infor Integrations

• Monitor API usage and error logs through Infor ION Desk or external monitoring tools
• Stay updated on API version changes
• Implement real-time alerts for failures or performance degradation

Optional Enhancements for Infor Integrations

• Middleware orchestration with Infor ION or third-party tools like MuleSoft
• Real-time updates using event-driven integrations
• Admin dashboards for monitoring and alerting
• Building audit trails for compliance and security

Summary

Building strong Infor integrations enables businesses to achieve seamless data flow and operational automation. This DIY Developer Guide for Infor provides the essential steps to create powerful, secure, and scalable custom integrations.
