Lovable and Yodlee integration: Step-by-Step Guide 2025

 

Setting Up Yodlee Integration Configuration

 

• Create a new file named yodleeConfig.ts in your project’s configuration folder (or at the project root if no config folder exists).
• This file will store your Yodlee credentials and API endpoints. Add the following code to yodleeConfig.ts:

// yodleeConfig.ts
export const YodleeConfig = {
  clientId: 'YOURYODLEECLIENT_ID',       // Replace with your Yodlee Client ID
  clientSecret: 'YOURYODLEECLIENT_SECRET', // Replace with your Yodlee Client Secret
  apiBaseUrl: 'https://api.yodlee.com/ysl'   // Yodlee base API endpoint
};

 

Installing Necessary Dependencies

 

• Since Lovable doesn’t have a terminal, you need to manually add dependency entries in your package.json file.
• Add an entry for node-fetch in the dependencies section. Open your package.json and insert the following snippet within the dependencies object:

{
  "dependencies": {
    "node-fetch": "^2.6.7"
  }
}

• If you already have a package.json, just add the node-fetch line in the dependencies section. Lovable will pick this up when rebuilding your project.

 

Creating the Yodlee Integration Service

 

• Create a new file called yodleeService.ts in your services or integrations folder within the project.
• This file will encapsulate calls to the Yodlee API. Insert the following TypeScript code in yodleeService.ts:

import fetch from 'node-fetch';
import { YodleeConfig } from './yodleeConfig';

export class YodleeService {
  private token: string | null = null;

  // Method to obtain Yodlee access token
  public async authenticate(): Promise<string> {
    const url = ${YodleeConfig.apiBaseUrl}/auth/token;
    const body = {
      clientId: YodleeConfig.clientId,
      clientSecret: YodleeConfig.clientSecret
    };

    const response = await fetch(url, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify(body)
    });

    if (!response.ok) {
      throw new Error(Authentication failed with status: ${response.status});
    }

    const data = await response.json();
    this.token = data.token;
    return this.token;
  }

  // Example method to retrieve account information
  public async getAccounts(): Promise<any> {
    if (!this.token) {
      await this.authenticate();
    }
    const url = ${YodleeConfig.apiBaseUrl}/accounts;
    const response = await fetch(url, {
      method: 'GET',
      headers: {
        'Authorization': Bearer ${this.token},
        'Content-Type': 'application/json'
      }
    });

    if (!response.ok) {
      throw new Error(Failed to fetch accounts: ${response.status});
    }

    return await response.json();
  }
}

 

Integrating Yodlee Service Into Your Lovable Project

 

• In the main part of your Lovable project (for example, in a file named app.ts or similar), import and utilize the YodleeService.
• Add the following code snippet where you handle your integration logic:

import { YodleeService } from './yodleeService';

async function integrateYodlee() {
  const yodleeService = new YodleeService();

  try {
    // Authenticate and get token
    const token = await yodleeService.authenticate();
    console.log('Yodlee Authenticated. Token:', token);

    // Fetch accounts from Yodlee
    const accounts = await yodleeService.getAccounts();
    console.log('Yodlee Accounts:', accounts);

    // Proceed with additional Yodlee related logic here...
  } catch (error) {
    console.error('Yodlee integration error:', error);
  }
}

// Call the integration function where appropriate in your project flow
integrateYodlee();

 

Placing the Code in Your Project

 

• Place yodleeConfig.ts and yodleeService.ts in your project’s directory structure such as under a folder labeled config or services.
• Update your main project file (e.g., app.ts or similar) with the integration code shown above.
• Lovable will automatically rebuild and bundle these files; no terminal commands are needed.

 

Final Testing of the Integration

 

• After adding the code, run your Lovable project as you normally would.
• Check the console output to verify that Yodlee authentication is successful and that account data is being fetched.
• If errors occur, confirm that your Yodlee credentials and API endpoint in yodleeConfig.ts are correct.
