Is There a Sage 100 API? Here's What You Need to Know

For businesses using Sage 100, pulling data for reporting, automation, or integration with other systems is a common need. Whether you’re syncing inventory with an eCommerce platform or automating invoice creation, a frequent question arises: Does Sage 100 have an API? The short answer is no—Sage 100 does not offer a native API. However, third-party solutions like Kissinger’s Web-Stor provide a robust REST API to bridge this gap, enabling seamless data access and automation.

In this guide, we’ll explore why Sage 100 lacks a native API, how Web-Stor’s REST API works, and the steps to set up secure, automated integrations. We’ll cover setting up a sandbox environment, writing JavaScript code to interact with the API, and best practices to ensure reliability and security. By the end, you’ll understand how to leverage Web-Stor and Kissinger Associates’ expertise to streamline your Sage 100 operations.

What You Need To Know About Sage 100 API

Key Takeaways

  • Sage 100 doesn't have a built-in API—but there are solutions to fill this gap
  • Most direct data pulls rely on ODBC connections or third-party tools
  • Understanding your actual requirements (real-time vs. scheduled reports) is crucial before investing in a solution
  • Third-party tools like Kissinger's Web-Stor can provide REST API functionality for Sage 100

The Short Answer: No Built-in API

  • Sage 100 doesn't have a built-in API
  • Most direct data pulls rely on ODBC (unless you're using the Premium/SQL version) or third-party add-ons
  • "API" means different things to different people
  • Sometimes all that's needed is automated exports—not a true real-time API

Sage 100 currently relies primarily on ODBC and COM-based interfaces, not a native REST API. However, developers can build RESTful endpoints through middleware or by using third-party tools to expose Sage 100 data in a REST-compatible format.

Third-Party Solutions Fill the Gap

Since there isn't a native Sage 100 API, it comes down to tools like third-party providers to fill the gap. Companies like Kissinger Associates have developed solutions that create REST API functionality for Sage 100.

How Third-Party APIs Work

These solutions typically work by:

  • Building a REST API with frameworks like Laravel
  • Getting data from Sage 100 business objects through staging tables
  • Providing a queueable interface that allows users to POST data to Sage 100
  • Using JSON for data transmission

Setting Up API Access

Environment Setup

For businesses working with third-party API solutions, you can typically set up a sandbox environment for safe experimentation. This might include:

  • A Swagger page for testing API endpoints
  • Access through a test company environment
  • Safe testing without impacting live business data

Authentication and Security

Modern third-party solutions implement secure authentication methods:

  • Personal access tokens (using systems like Laravel Sanctum)
  • TLS encryption for data transmission
  • Role-based access control for sensitive information

Common Use Cases for Sage 100 API Integration

Top use cases include:

  • Automating invoice and sales order entry
  • Real-time inventory data syncing with eCommerce platforms
  • Integrating CRM tools with customer and order data
  • Building custom reporting dashboards
  • Automating EDI or 3PL workflows

Getting Started with Web-Stor’s REST API for Sage 100


Web-Stor’s REST API, built with Laravel, acts as a middleware layer to connect Sage 100 with external systems. It retrieves data from staging tables populated by Sage 100 business objects and supports POST requests to push data back via a queueable interface. Data is exchanged in JSON format, making it developer-friendly.

Steps to Begin:

1. Set Up a Sandbox
Use Web-Stor’s Swagger page to test endpoints, or create a test Web-Stor company to mimic your Sage 100 setup. This allows for safe experimentation.

2. Secure Authentication
Obtain a personal access token via Laravel Sanctum from Kissinger Associates. Store it securely using environment variables or a secure vault.

3. Explore Documentation
The Swagger page provides partial documentation with endpoints like /invoices or /customers. Full documentation is currently under development.

4. Test Connectivity
Send a GET request (e.g., to /invoices) using the Swagger page or tools like Postman. Confirm a successful response in your sandbox to verify the setup.

This configuration enables automation of tasks like invoice creation and inventory syncing—tailored to your business needs.

Best Practices for Web-Stor API Integration

To ensure a reliable Web-Stor integration, follow these practices tailored to its REST API:

1. Security
Use TLS encryption for all API calls, and store Laravel Sanctum tokens in secure vaults.
Implement role-based access control to restrict access to authorized users.
Rotate tokens regularly to maintain security best practices.

2. Performance
Optimize API queries—for example, use filters like ?date=2025-06-16 to reduce data loads.
Cache frequently accessed data locally to limit unnecessary API calls.
Monitor response times to detect and address performance bottlenecks.

3. Documentation
Refer to the Swagger page for currently available endpoint details.
Note: full documentation is still in development.
Maintain internal documentation to support your team and simplify troubleshooting.

4. Testing
Test all operations in the Swagger interface or against a test Web-Stor company before deploying to production.
Simulate edge cases—like rate limits or malformed JSON payloads—to ensure system resilience.
Automate your tests using tools like Postman for efficiency and consistency.

These practices help you get the most out of Web-Stor’s Laravel-based architecture, enabling secure and efficient integrations.
