Installation

pip install ldc-xac

Quick Start

Basic Usage

import logging
from ldc_xac import make_external_api_request

# Configure logging to see API call logs
logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
)

# Make a simple GET request
response = make_external_api_request(
    url="https://api.example.com/data",
    method="GET",
    api_code="EXAMPLE_API",
    system="MY_SYSTEM"
)

print(f"Status: {response.status_code}")
print(f"Response: {response.json()}")

POST Request with JSON Data

response = make_external_api_request(
    url="https://api.example.com/users",
    method="POST",
    json={"name": "John Doe", "email": "[e-mail]"},
    api_code="CREATE_USER",
    system="USER_MANAGEMENT"
)

Handling SSL Issues

# For testing with self-signed certificates or SSL issues
response = make_external_api_request(
    url="https://api.example.com/data",
    method="GET",
    api_code="EXAMPLE_API",
    system="MY_SYSTEM",
    verify=False  # Disable SSL verification
)

Advanced Usage

Manual Logging Control

from ldc_xac import ExternalAPICaller
import requests

# Log a request manually
start_time = ExternalAPICaller.log_external_api_request(
    url="https://api.example.com/users",
    method="POST",
    api_code="CREATE_USER",
    system="USER_MANAGEMENT"
)

# Make your request
response = requests.post(
    "https://api.example.com/users",
    json={"name": "John Doe", "email": "[e-mail]"}
)

# Log the response
ExternalAPICaller.log_external_api_response(
    url="https://api.example.com/users",
    response=response,
    start_time=start_time,
    api_code="CREATE_USER",
    system="USER_MANAGEMENT"
)

Request with Headers and Parameters

response = make_external_api_request(
    url="https://api.example.com/search",
    method="GET",
    headers={
        "Authorization": "Bearer your-token",
        "Content-Type": "application/json"
    },
    params={"q": "search term", "limit": 10},
    api_code="SEARCH_API",
    system="SEARCH_SYSTEM"
)

Configuration

The package uses the following default configuration:

• MAX_REQUEST_BODY_SIZE: 10,000 characters (configurable in ldc_xac.config)
