how to get the access of the value from outside request npm pacakgesome example in post method

Assuming you are using the request package in Node.js, you can access the value returned by the API in the callback function of the post method. Here is an example:

const request = require('request');

const options = {
  url: 'https://example.com/api',
  method: 'POST',
  json: true,
  body: { key: 'value' }
};

request(options, (error, response, body) => {
  if (error) {
    console.error(error);
    return;
  }

  // Access the value returned by the API
  console.log(body.key);
});

In this example, we are sending a POST request to https://example.com/api with a JSON body containing a key-value pair. In the callback function, we check for any errors and then log the value returned by the API (body.key).

Note that the request package is deprecated and you should consider using other HTTP client libraries like Axios or node-fetch.
