Implementing API with Nodejs Application : A step by step guide




Before we begin, make sure you have the following:

1.Basic understanding of JavaScript and Node.js.
2.Node.js installed on your machine.
3.Access to the API key and X-USER-ID.
4.Familiarity with making HTTP requests using Axios or a similar library.


Step 1: Setting Up Your Node.js Project
First, create a new directory for your Node.js project and initialize a new Node.js project inside it. Open your terminal and execute the following commands.


mkdir playht-nodejs
cd playht-nodejs
npm init -y


Step 2: Installing Dependencies
Next, install the necessary dependencies for your project. Since we'll be making HTTP requests to the API, we'll use Axios for this purpose:


npm install axios dotenv express


Step 3: Environment Configuration
Create a .env file in your project directory to store your environment variables, including your API key and X-USER-ID:




Replace YOUR_PLAY_HT_API_KEY and YOUR_PLAY_HT_X_USER_ID with your actual API key and X-USER-ID.


Step 4: Writing the Integration Code
Create a new file named playhtIntegration.js in your project directory and add the following code:


const axios = require('axios');

const PlayHt = async (prompt) => {
    try {
        const url = '';
        const data = {
            text: prompt,
            voice: 's3://voice-cloning-zero-shot/d9ff78ba-d016-47f6-b0ef-dd630f59414e/female-cs/manifest.json',
            output_format: 'mp3',
            voice_engine: 'PlayHT2.0'
        const headers = {
            accept: 'text/event-stream',
            'content-type': 'application/json',
            AUTHORIZATION: process.env.PLAY_HT_API_KEY,
            'X-USER-ID': process.env.PLAY_HT_X_USER_ID,
        const response = await, data, { headers });
        const speech_url = `${`"url":"`)[1].split(`mp3`)[0]}mp3`;
        return speech_url;
    } catch (error) {
        console.error('Error generating speech:', error);
        throw new Error('Failed to generate speech');


Step 5: Integrating with Your Application
Now that you've implemented the integration code, you can integrate it into your Node.js application. Import the PlayHt function into your application's code wherever you need to generate speech from text, and call it with the desired text prompt.


Step 6: Testing Your Integration
You can test your integration by calling the PlayHt function with a text prompt and observing the generated speech URL. Ensure that your API credentials are correctly set up in your environment variables and that your application can successfully make requests to the API endpoint.
