v0 and Infusionsoft by Keap integration: Step-by-Step Guide 2025

 

Setting Up Project Dependencies

 

• Create or update your package.json file in the project root with the following content. This tells your project which dependencies to use. Since v0 doesn't have a terminal, you need to copy this content into your package.json file to “install” dependencies.

{
  "name": "v0-infusionsoft-integration",
  "version": "1.0.0",
  "description": "Integration with Infusionsoft by Keap",
  "main": "index.js",
  "scripts": {
    "start": "node dist/index.js",
    "build": "tsc"
  },
  "dependencies": {
    "axios": "^1.4.0"
  },
  "devDependencies": {
    "typescript": "^5.0.4",
    "@types/node": "^20.0.0"
  }
}

• If your project does not already have TypeScript configured, create a file named tsconfig.json in your project root with the following content:

{
  "compilerOptions": {
    "target": "ES6",
    "module": "CommonJS",
    "outDir": "./dist",
    "rootDir": "./src",
    "strict": true,
    "esModuleInterop": true
  }
}

 

Creating the Keap Integration Service

 

• Create a new folder named src in your project root if one does not exist.
• Inside the src folder, create a file named keapService.ts. This file will contain the functions to interact with Infusionsoft’s REST API.
• Copy and paste the following code snippet into the keapService.ts file. Replace the placeholder strings with your actual Infusionsoft (Keap) credentials.

import axios from 'axios';

// Replace these constants with your actual Infusionsoft (Keap) credentials
const INFUSIONSOFTTOKENURL = 'https://api.infusionsoft.com/token';
const CLIENTID = 'YOURCLIENT_ID';
const CLIENTSECRET = 'YOURCLIENT_SECRET';
const REDIRECTURI = 'YOURREDIRECT_URI';

export async function getAccessToken(refreshToken: string): Promise<string> {
  try {
    const response = await axios.post(INFUSIONSOFTTOKENURL, null, {
      params: {
        granttype: 'refreshtoken',
        refresh_token: refreshToken,
        clientid: CLIENTID,
        clientsecret: CLIENTSECRET,
        redirecturi: REDIRECTURI,
      },
    });
    return response.data.access_token;
  } catch (error) {
    console.error('Error refreshing access token', error);
    throw error;
  }
}

export async function createContact(
  token: string,
  contactData: { email: string; givenname: string; familyname: string }
): Promise<any> {
  const url = 'https://api.infusionsoft.com/crm/rest/v1/contacts';
  try {
    const response = await axios.post(url, contactData, {
      headers: {
        Authorization: Bearer ${token},
        'Content-Type': 'application/json',
      },
    });
    return response.data;
  } catch (error) {
    console.error('Error creating contact', error);
    throw error;
  }
}

 

Integrating the Keap Service into Your Project

 

• Within the src folder, create a new file named index.ts. This file serves as the starting point for using the Keap integration.
• Copy and paste the following code snippet into index.ts. This code demonstrates how to retrieve an access token using a refresh token and create a new contact using that access token.

import { getAccessToken, createContact } from './keapService';

// Replace 'YOURREFRESHTOKEN' with your actual refresh token from Infusionsoft (Keap)
const refreshToken = process.env.KEAPREFRESHTOKEN || 'YOURREFRESHTOKEN';

async function runIntegration() {
  try {
    const token = await getAccessToken(refreshToken);
    console.log('Access Token:', token);
    
    // Example of creating a contact
    const newContact = await createContact(token, {
      email: '[email protected]',
      given_name: 'John',
      family_name: 'Doe'
    });
    console.log('New Contact created:', newContact);
  } catch (error) {
    console.error('Integration error:', error);
  }
}

runIntegration();

• If you do not have environment variable support in v0, replace the process.env.KEAPREFRESHTOKEN expression with your actual refresh token string in the code.

 

Building and Running the Project

 

• Since v0 doesn’t have a terminal, add the build and run steps directly into your project’s code. Make sure you compile your TypeScript code to JavaScript. If your v0 environment automatically compiles TypeScript, ensure that the output directory is set to ./dist as specified in the tsconfig.json.
• When ready, trigger your project’s run command through your v0 interface. The entry point should be the index.js file located in the dist folder.

 

Testing the Integration

 

• After running the project, check your v0 project logs for the output from the console.log statements. These logs should display the acquired access token and the details of the newly created contact.
• If any errors occur, review the error logs to adjust your credentials or contact data as needed.

 

Finalizing Your Integration

 

• Review and replace all placeholder values such as YOURCLIENTID, YOURCLIENTSECRET, YOURREDIRECTURI, and YOURREFRESHTOKEN with your actual Infusionsoft (Keap) account details.
• Once you confirm that the integration works correctly, save all files and commit your changes if using version control.
• Your v0 project is now integrated with Infusionsoft by Keap, allowing you to refresh access tokens and create contacts via their API.
