Cannot get Token in node js

Developer API
1

I cannot get Token in node js with upstox-js-sdk as well as with API.

const UpstoxClient =require (‘upstox-js-sdk’)
let apiInstance = new UpstoxClient.LoginApi();
let apiVersion = “2.0”;
let opts = {
“code”: “*******”,
“client_id”: “***",
“client_secret”: "”,
“redirect_uri”: “https://moneymakers-algo.com”,
“grant_type”: “authorization_code”
};

apiInstance.token(apiVersion, opts, (error, data, response) => {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ’ + data);
}
});

const url = ‘https://api-v2.upstox.com/login/authorization/token’;
const headers = {
‘Accept’: ‘application/json’,
‘Api-Version’: ‘2.0’,
‘Content-Type’: ‘application/x-www-form-urlencoded’,
};

const data = {
“code”: “",
“client_id”: “***********”,
“client_secret”: "”,
“redirect_uri”: “link”,
“grant_type”: “authorization_code”
};

fetch(url, {
method: ‘POST’,
headers: headers,
body: data,
})
.then(response => response.json())
.then(data => {
console.log(‘Response:’, data);
// Handle the response data
})
.catch(error => {
console.error(‘Error:’, error);
// Handle fetch errors
});

Could you please share the exact error or a screenshot of the error you’re encountering while trying to obtain the access token?

I suggest using the cURL command to verify whether you can successfully generate an access token. This will help ensure that all parameters are correctly set:

curl -X 'POST' 'https://api.upstox.com/v2/login/authorization/token' \
-H 'accept: application/json' \
-H 'Api-Version: 2.0' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-d 'code={your_code}&client_id={your_client_id}&client_secret={your_client_secret}&redirect_uri={your_redirect_url}&grant_type=authorization_code'

Feel free to attempt the following, and please inform me about the outcome. The code provided below has been verified and is operational

let UpstoxClient = require('upstox-js-sdk');

let apiInstance = new UpstoxClient.LoginApi();
let apiVersion = "2.0"; 
let opts = { 
  'code': "{your_atuh_code}", 
  'clientId': "{ypur_client_code}",
  'clientSecret': "{ypur_client_secret}", 
  'redirectUri': "{your_redirect_uri}",
  'grantType': "authorization_code" 
};
apiInstance.token(apiVersion, opts, (error, data, response) => {
  if (error) {
    console.error(error);
  } else {
    console.log('Returned data: ' + JSON.stringify(data));
  }
});

here is the error

Ensure you use the correct auth code. It’s crucial to understand that this code is for one-time use only; once used, it will become invalid and may cause the “Invalid Auth code” issue.

Thank you. It’s working with Api now.
