SDK

The SDK (Software Development Kit) is a set of tools and libraries that developers can use to integrate WELL3's features into their own applications. Here's a step-by-step guide to get you started:

Step 1: Set Up Your Development Environment

1. Install Node.js: Ensure you have Node.js installed on your system. You can download it from the official Node.js website.

2. Create a New Project: Create a new directory for your project and initialize it with npm init to create a package.json file.

Step 2: Install the WELL3 SDK

1. Install the SDK: Use npm to install the WELL3 SDK by running the following command: bash npm install well3-sdk

Step 3: Initialize the SDK

1. Import the SDK: In your project's main file (e.g., index.js), import the WELL3 SDK: javascript const WELL3 = require('well3-sdk');

Step 4: Connect to the WELL3 Platform

1. Initialize the SDK: Create an instance of the SDK and connect to the WELL3 platform: javascript const well3 = new WELL3({ apiKey: 'YOUR_API_KEY', apiSecret: 'YOUR_API_SECRET' });

Step 5: Use SDK Features

1. Fetch User Data: Use the SDK to fetch user data from the WELL3 platform: javascript well3.getUserData(userId, (err, data) => { if (err) { console.error('Error fetching user data:', err); } else { console.log('User data:', data); } });

2. Submit Health Data: Submit health data to the WELL3 platform: javascript well3.submitHealthData(userId, healthData, (err, response) => { if (err) { console.error('Error submitting health data:', err); } else { console.log('Health data submitted successfully:', response); } });

3. Earn Rewards: Use the SDK to check and redeem rewards: javascript well3.checkRewards(userId, (err, rewards) => { if (err) { console.error('Error checking rewards:', err); } else { console.log('Rewards:', rewards); } });

Step 6: Handle Errors

1. Error Handling: Implement error handling to manage any issues that arise during SDK usage: javascript try { // SDK operations } catch (error) { console.error('An error occurred:', error); }

This is a basic guide to get projects started with the WELL3 SDK. Please refer to the official WELL3 documentation for more detailed information and advanced features.
