API Gateway & DynamoDB Utility Library

Overview

This library provides utility functions to interact with AWS API Gateway and DynamoDB. It enables secure API communication for fetching and upserting data via API Gateway, ensuring robust error handling, logging, and authentication using an API Key.

Features

• ✅ Fetch Data from DynamoDB via API Gateway
• ✅ Upsert Data (Insert/Update) into DynamoDB
• ✅ Secure API Access using API Key
• ✅ Robust Logging & Error Handling
• ✅ Optimized JSON Response Handling
• ✅ Support for Private Repository Deployment

Installation

Prerequisites

Ensure you have Python 3.8+ installed.

Install the required dependencies:

pip install requests
pip install api_gateway_dynamodb 

Usage - Read Data

 from api_gateway_dynamodb import get_data_from_api_gateway_dynamodb

# API Gateway Endpoint URL
api_url = "https://your-api-gateway-url.com/get-data"

# Example Parameters
database_table_name = "customer"
partition_key = "customer_id"
partition_key_value = "123456"
api_key = "your-api-key-here"

# Fetch data
response = get_data_from_api_gateway_dynamodb(api_url, 
                                              database_table_name, 
                                              partition_key, 
                                              partition_key_value, 
                                              api_key)

print(response)  # Output: JSON response with data from DynamoDB

Usage - Insert / Update data

from api_gateway_dynamodb import upsert_data_via_api_gateway_dynamodb

# API Gateway Endpoint URL
api_url = "https://your-api-gateway-url.com/upsert-data"

# Example Data Payload
payload = {
    "id_number": "123456",
    "name": "John",
    "surname": "Doe",
    "title": "Mr"
}

# Upsert Parameters
method_name = "insert"
table_name = "customer"
partition_key = "id_number"
api_key = "your-api-key-here"

# Insert or Update Data
response = upsert_data_via_api_gateway_dynamodb(payload, method_name, table_name, partition_key, api_key, api_url)

print(response)  # Output: JSON response confirming the operation
