API Integration Outline

This outline describes how the chat widget interacts with external APIs such as OpenAI, handling requests, processing responses, and using third-party libraries for API calls.

API Interaction:

• The chat widget interacts with external APIs to enhance its functionality. For instance, it might leverage OpenAI’s API for natural language processing tasks.
• When a user interacts with the chat widget, the user’s input is formatted into an API request, then sent to the external API.
• The widget processes the API response and presents the results to the user.

HTTP Requests and API Authentication:

• The chat widget uses HTTP requests to communicate with the API. Typically, these requests are made using the POST method.
• API authentication is handled through bearer tokens.
• The bearer token, often stored securely, is included in the request header to verify access and authorization.

Third-Party Libraries for API Calls:

• The chat widget utilizes libraries like axios or fetch to simplify API calls.
• axios and fetch offer features like:
  • Simplified syntax for sending HTTP requests.
  • Promise-based APIs for asynchronous operations.
  • Handling response data.

Example API Integration Using Axios:

// Assuming you have a bearer token stored in a variable called 'authToken'
          import axios from 'axios';
          
          const apiEndpoint = 'https://api.openai.com/v1/completions'; // Replace with your actual OpenAI API endpoint
          
          const requestBody = {
            // Your API request body with required parameters
          };
          
          axios.post(apiEndpoint, requestBody, {
            headers: {
              'Authorization': `Bearer ${authToken}`
            }
          })
            .then(response => {
              // Handle successful API response
              console.log(response.data);
            })
            .catch(error => {
              // Handle API error
              console.error(error);
            });
          

Example API Integration Using Fetch:

// Assuming you have a bearer token stored in a variable called 'authToken'
          const apiEndpoint = 'https://api.openai.com/v1/completions'; // Replace with your actual OpenAI API endpoint
          
          const requestBody = {
            // Your API request body with required parameters
          };
          
          fetch(apiEndpoint, {
            method: 'POST',
            headers: {
              'Content-Type': 'application/json',
              'Authorization': `Bearer ${authToken}`
            },
            body: JSON.stringify(requestBody)
          })
            .then(response => {
              // Handle successful API response
              return response.json();
            })
            .then(data => {
              // Process API response data
              console.log(data);
            })
            .catch(error => {
              // Handle API error
              console.error(error);
            });
          

This outline provides a high-level understanding of the API integration within the chat widget. It emphasizes the core concepts of HTTP requests, authentication, and response handling, highlighting the use of libraries like axios and fetch for API calls.
