User's Guide: Google Address Validation API and Place Details API

Introduction:

The Google Address Validation API and Place Details API are powerful tools offered by Google Maps Platform to enhance the accuracy and efficiency of address handling processes in your applications. This user's guide will walk you through how to use these APIs effectively and understand their responses.

Google Address Validation API:

Purpose:

The Address Validation API helps verify, standardize, and geocode addresses, ensuring data accuracy and improving delivery success rates.

How to Use:

  1. Request Format: Send a HTTP request to the API endpoint with the address details as parameters.

  2. API Request URL: The API request URL typically looks like this:

     POST https://maps.googleapis.com/maps/api/geocode/json

    Include the address data in the request body as JSON:

     {
   "address": "100 Main Street, Anytown, CA 12345, US",
   "key": "YOUR_API_KEY"
 }

    Replace "YOUR_API_KEY" with your actual API key obtained from Google Cloud Console.

  3. Response Structure: Receive a JSON response containing various elements such as input address, standardized address, output components, geocoder requested output location, address types, match type, validation results, and optionally, a place ID.

  4. Response Interpretation: Understand each element of the response to validate address components, standardize address format, obtain geographic coordinates, assess address types, and review validation results.
