API Integration Knowledgebase

Introduction to API Integration

This article explains the fundamental principles of integrating different APIs to build robust and scalable applications.

Key concepts include: REST APIs, GraphQL, data exchange, and integration strategies.

Common Integration Patterns

Several patterns streamline API interactions:

• REST API Calls: Directly call APIs using HTTP methods.
• GraphQL API: Define the data required and fetch it using a query.
• Webhooks: Automatic API responses triggered by events.

Example: Fetching Data

Let's illustrate with a simple example: Fetching weather data from OpenWeatherMap.

First, you'll need an API key from OpenWeatherMap. (Link: https://openweathermap.org/api)

Using Python with the `requests` library, you can make a call:

```python import requests response = requests.get('https://api.openweathermap.org/data/2.5/weather?q=London&appid=YOUR_API_KEY') print(response.json()) ```
