Quick Start
Follow these steps to stand up a working integration quickly
Before You Begin
Download the Developer Integration Kit
The Developer Integration Kit is the fastest way to get started.
It includes:
- Complete API documentation
- Sample requests and responses
- A Postman collection
- An AI integration accelerator (located in the
skills/folder) that works with Cursor and other AI-assisted IDEs
Download the ZIP file from the Client Support Center and open it in your IDE. After providing your API key, the included copilot can guide you through:
- Authentication
- Request construction
- Payload validation
- Response interpretation
Using the provided samples and tools, you can stand up and test a working integration in minutes. As a reminder, you can integrate in three quick steps:
- Your application retains the STE payroll calculation log or JSON request (the payroll context)
- You send that data to the STL API
- The API returns a structured explanation and you display in your UI
Option 1: Test with Postman (recommended first step)
The fastest way to see STL in action is with the provided Postman collection.
Download Full Postman Collection
The complete Postman collection and environment files are available in the Symmetry Client Support Center.
Clients can log in to download the ready-to-run collection. If you're evaluating Symmetry Tax Logic API, reach out for more information!
Option 2: Run a Sample Client
Pick your language and follow the README in the corresponding folder within the Developer Integration Kit.
