Dynamics GP Developer DIY Guide: Building Custom Integrations for Microsoft Dynamics GP

This DIY Developer Guide for Microsoft Dynamics GP offers a comprehensive approach to designing secure, scalable, and efficient custom integrations. Microsoft Dynamics GP, also known as Great Plains, is a robust enterprise resource planning (ERP) software solution featuring core modules for financial management and business operations. Dynamics GP supports integration through eConnect (XML-based APIs), Web Services, and direct SQL access.

Whether you’re automating invoice generation, synchronizing customer data, or integrating supply chain workflows, mastering Microsoft Dynamics GP integrations allows you to streamline business processes and enhance operational efficiency.

Prerequisites for Microsoft Dynamics GP Integrations

• Access to a Microsoft Dynamics GP environment
• eConnect installed and configured (for XML APIs)
• Familiarity with:
• XML data formats
• REST/SOAP Web Services
• SQL Server and Stored Procedures (optional for direct database integrations)
• Tools: Postman, SQL Server Management Studio, eConnect SDK, Visual Studio

Strong technical expertise is crucial for a Dynamics GP developer, encompassing proficiency with integration tools and a thorough understanding of data structures to effectively manage and customize the system.

Understanding Dynamics GP Data

Ensuring your Dynamics GP data is accurate isn’t just a best practice—it’s vital for your business growth. Your GP system contains all the critical information that drives your operations: financial transactions, inventory levels, sales data, and human resources records. All this information resides within your company database, accessible through GP’s interface, Web Services, or Integration Manager.

But here’s the catch: poor data management drains efficiency. We assist businesses in mastering their GP data structures and connections so that systems communicate seamlessly—eliminating manual data transfers and integration frustrations. When you grasp how your data flows and interlinks, you safeguard what matters most. Your processes become smoother, your GP environment remains stable, and your team can focus on growth instead of battling data issues.

Integration Tools and Technologies

Microsoft Dynamics GP is equipped with powerful integration tools designed to solve real-world challenges. Web Services, eConnect, and Integration Manager are not just technical jargon—they’re your solution to eliminating manual data entry and disconnected systems. These tools provide secure and flexible access to your business data, freeing you from the hassles of spreadsheets and allowing you to focus on what truly matters. Say goodbye to tedious copy-pasting and data errors that slow down your operations.

Visual Studio Tools for Microsoft Dynamics GP elevate your capabilities by allowing you to create tailored solutions that align perfectly with your business operations. These smart integrations enable automated workflows, synchronized systems, and a Dynamics GP environment that evolves alongside your business rather than limiting it. The key is selecting the ideal combination of tools to meet your unique requirements. When done right, your integration projects deliver genuine value without adding unnecessary complexity.

Step 1: Authentication for Microsoft Dynamics GP Integrations

Microsoft Dynamics GP integrations use:

• Windows Authentication (for internal APIs)
• Basic Authentication for Web Services (if configured externally)

Example (Basic Auth Header):

Authorization: Basic base64(username:password)

For SQL-based integrations, ensure secure database credentials are used and connections are encrypted.

Step 2: Endpoint Discovery and Data Mapping for Microsoft Dynamics GP Integrations

Common API Resources:

• Customers and Vendors
• Sales Orders and Purchase Orders
• Inventory Items
• Financial Transactions
• Employee and Payroll Data

Process:

• Review the eConnect documentation and available Web Services.
• Map external system fields carefully to Microsoft Dynamics GP tables, business objects, and the appropriate databases.
• Ensure proper data access permissions are configured and that mapping is aligned with the correct databases to maintain data integrity and security.

Important considerations:

• Required vs. optional fields
• Using primary and foreign keys correctly (e.g., linking Invoices to Customers)
• Formatting for amounts, dates, and record identifiers
• Configuring user accounts and defining tasks is essential to control access to sensitive data and manage permissions during integration.

Step 3: Building Integration Flows for Microsoft Dynamics GP

Integration Patterns: Connecting Dynamics GP with other business systems is a crucial initiative for many organizations, facilitating seamless data exchange and enhanced functionality. Each integration effort may involve linking Dynamics GP to CRM platforms, e-commerce solutions, or proprietary applications.

• Inbound (to GP): Create or update records via eConnect XML or Web Services. When integrating Dynamics GP, it is important to implement business logic within eConnect or stored procedures to ensure data integrity and process consistency.
• Outbound (from GP): Query records through Web Services or direct SQL reads

Example: Creating a Customer via eConnect:

  
    
    
      CUST001
      Contoso Ltd
      123 Main St

Example: Retrieving Sales Orders via Web Services:

GET /SalesOrderService/SalesOrder/{OrderNumber}

Step 4: Error Handling and Pagination for Microsoft Dynamics GP Integrations

Error Handling:

• Capture error codes returned from eConnect or Web Services.
• Implement retries for transient errors and log detailed error messages.
• Identify and address common integration errors by analyzing logs and error codes.
• Addressing issues promptly helps maintain data accuracy and system reliability.

Pagination:

• For Web Services, use paging parameters where supported.
• For direct SQL reads, implement OFFSET and FETCH clauses.

Example:

SELECT * FROM SOP30200 ORDER BY SOPNUMBE OFFSET 100 ROWS FETCH NEXT 50 ROWS ONLY;

Step 5: Testing and Validation for Microsoft Dynamics GP Integrations

• Test endpoints with Postman and SQL queries.
• Validate that created or updated records match business rules.
• Conduct stress tests to assess system performance under load.
• Thorough testing and validation are essential steps that contribute to overall system optimization.

Step 6: Deployment and Security of Microsoft Dynamics GP Integrations

• Deploy integration services securely within an internal network or private cloud.
• Store credentials securely and enforce strict access controls.
• Ensure HTTPS/TLS encryption for external Web Service calls.
• Enable comprehensive error logging and auditing.

Step 7: Maintenance and Monitoring for Microsoft Dynamics GP Integrations

• Monitor API usage and eConnect service status.
• Keep track of database schema changes during GP upgrades, and ensure customizations compatibility when migrating to the latest version of Dynamics GP.
• Set up alerts for service downtime or integration errors.

These resources empower you not just to build solutions, but to build them right—so your integrations continue delivering value long after deployment.

Best Practices for Custom Integrations in Microsoft Dynamics GP

Effective Microsoft Dynamics GP integrations begin with the fundamentals: clean data, secure connections, and thorough testing before going live. Avoid shortcuts—data corruption drains productivity and wastes your team’s valuable time. Conduct regular integrity checks to maintain system health, and perform consistent database maintenance to prevent costly failures. By doing things right from the start, your GP system will work more efficiently, allowing your team to focus on what matters most.

Safeguard your data with robust user access controls that prevent unauthorized changes and simplify compliance. Design integrations that grow seamlessly alongside your business. While performance is important, maintainability is even more critical. Collaborate with seasoned GP developers who have in-depth system knowledge. Regular audits help identify issues before they escalate into major problems. The outcome? Dependable integrations that provide genuine value and align with your strategic objectives. Your operations become more efficient, your data remains accurate, and your business continues to thrive.

Optional Enhancements for Microsoft Dynamics GP Integrations

• Use middleware orchestration tools (like MuleSoft, Boomi)
