Integrate the zip.zax Sales Tax API in Your Python App

If you're building an application that requires accurate sales tax calculations, the zip.tax API is an excellent tool to integrate. This guide walks you through how to set up and use the zip.tax API in a Python application.

Prerequisites

Before getting started, ensure you have the following:

• Basic knowledge of Python.
• A Python development environment set up.
• An API key from zip.tax.

Step 1: Install Required Libraries

For making HTTP requests, we'll use Python's standard requests package. Additionally, we'll use json for parsing JSON responses.

Step 2: Set Up Your Python Project

Create a new project directory and initialize a new module:

Step 3: Write the Code

Here is a complete example of a simple Python application that queries the zip.tax API for sales tax information.

Explanation of the Code

1. API Request: The get_sales_tax function constructs a URL with the API key and an address, makes a GET request, and parses the response.
2. Response Parsing: The response JSON is unmarshalled for easy access to sales tax details.
3. Display Results: The main function prints the normalized address, lat/lng, and sales tax rate for the specified address code. You can use any of the response values here to output the data you need.

Step 4: Run the Application

Save the code to a file (e.g., main.py), then run the program:

You should see output similar to this:

Conclusion

Integrating the zip.tax API into your Python application is straightforward. By following this guide, you can enhance your application with accurate sales tax information based on address. For more details, refer to the official documentation.
