Bolt.new AI and Withings integration: Step-by-Step Guide 2025

 

Setting Up Withings API Credentials

 

• Create a new file named withingsConfig.ts in your project’s root folder. This file will store your Withings API credentials.
• Copy and paste the following code snippet into withingsConfig.ts. Replace the placeholder values with your actual Withings clientid, clientsecret, and redirect_uri:

export const WITHINGS_CONFIG = {
  clientId: "YOURWITHINGSCLIENT_ID",
  clientSecret: "YOURWITHINGSCLIENT_SECRET",
  redirectUri: "YOURREDIRECTURI",  // e.g., https://your-app.com/callback
  baseUrl: "https://wbsapi.withings.net"
};

 

Installing Dependencies via Code

 

• Bolt.new AI does not have a terminal for installing packages. Instead, include the following dependency declaration in your project’s existing package.json file. If you don’t have one, create it in your project’s root folder.
• Add an entry for axios under the dependencies section as shown below:

{
  "name": "your-bolt-ai-project",
  "version": "1.0.0",
  "dependencies": {
    "axios": "^1.4.0"
  }
}

 

Creating the Withings Integration Module

 

• Create a new file named withingsIntegration.ts in your project’s root folder.
• This module uses axios to interact with Withings API endpoints. Paste the following code snippet into withingsIntegration.ts:

import axios from "axios";
import { WITHINGS_CONFIG } from "./withingsConfig";

// Function to create the OAuth URL for Withings authorization
export function getWithingsAuthUrl(): string {
  const { clientId, redirectUri } = WITHINGS_CONFIG;
  // Withings OAuth authorization endpoint
  const authEndpoint = "https://account.withings.com/oauth2_user/authorize2";
  // Scopes required; adjust as necessary
  const scope = "user.metrics";
  return ${authEndpoint}?response_type=code&client_id=${clientId}&redirect_uri=${encodeURIComponent(redirectUri)}&scope=${scope};
}

// Function to exchange the authorization code for an access token
export async function getWithingsAccessToken(code: string): Promise {
  const { clientId, clientSecret, redirectUri } = WITHINGS_CONFIG;
  const tokenEndpoint = "https://account.withings.com/oauth2/token";

  const params = new URLSearchParams();
  params.append("granttype", "authorizationcode");
  params.append("client_id", clientId);
  params.append("client_secret", clientSecret);
  params.append("code", code);
  params.append("redirect_uri", redirectUri);

  try {
    const response = await axios.post(tokenEndpoint, params, {
      headers: { "Content-Type": "application/x-www-form-urlencoded" }
    });
    return response.data;
  } catch (error) {
    console.error("Error retrieving access token", error);
    throw error;
  }
}

// Example function to call Withings API to fetch measurements
export async function fetchWithingsMeasurements(accessToken: string): Promise {
  const endpoint = ${WITHINGS_CONFIG.baseUrl}/measure;
  const params = {
    action: "getmeas",
    access_token: accessToken
    // Add any additional parameters as required by the API documentation
  };

  try {
    const response = await axios.get(endpoint, { params });
    return response.data;
  } catch (error) {
    console.error("Error fetching measurements", error);
    throw error;
  }
}

 

Integrating Withings Module into Your Bolt.new AI Project

 

• Open your main project file (for example, index.ts or another entry point file where you handle API routes).
• Import the functions from the withingsIntegration.ts file to enable Withings integration within your project flow.
• Insert the following code snippet at the appropriate location in your file to handle the OAuth redirection and API calls:

import express from "express";  // Assuming you are using Express in your Bolt.new project
import { getWithingsAuthUrl, getWithingsAccessToken, fetchWithingsMeasurements } from "./withingsIntegration";

const app = express();

// Route to redirect users to Withings OAuth URL
app.get("/withings/login", (req, res) => {
  const authUrl = getWithingsAuthUrl();
  res.redirect(authUrl);
});

// Callback route that Withings will redirect to after authentication
app.get("/callback", async (req, res) => {
  const authCode = req.query.code as string;
  if (!authCode) {
    return res.status(400).send("Authorization code not provided");
  }
  try {
    const tokenData = await getWithingsAccessToken(authCode);
    // Use tokenData.access_token for further API calls
    const measurements = await fetchWithingsMeasurements(tokenData.access_token);
    res.json({ tokenData, measurements });
  } catch (e) {
    res.status(500).send("Error during Withings integration");
  }
});

// Start the server (ensure Bolt.new AI suits web server setup)
app.listen(process.env.PORT || 3000, () => {
  console.log("Server running on port", process.env.PORT || 3000);
});

 

Finalizing Your Integration

 

• Ensure that your redirectUri value in withingsConfig.ts matches the callback route you defined (for example, https://your-app.com/callback).
• Review the Withings API documentation to adjust scopes and parameters as needed for your intended functionality.
• Save all files. Bolt.new AI will automatically detect changes and deploy your updated code.
