Integrate the Spotify API in JavaScript

Refresh Access Tokens

Understand how to refresh Spotify API access tokens using client credentials and authorization code methods. This lesson helps you maintain seamless access to Spotify's data by generating new tokens when needed, supporting ongoing API integration.

We'll cover the following...

Client credential access token

Click the "Run" button to generate a new client credential access token.

Javascript (babel-node)
const endpointUrl = new URL('https://accounts.spotify.com/api/token');
const queryParameters = new URLSearchParams({
  grant_type: 'client_credentials'
});
const required_ids = Buffer.from('{{CLIENT_ID}}:{{CLIENT_SECRET}}');
const encoded = required_ids.toString('base64');
headerParameters = {
    'Content-Type': 'application/x-www-form-urlencoded',
    'Authorization': 'Basic '+encoded
}
const options = {
  method: 'POST',
  headers: headerParameters
};
async function fetchAccessToken() {
  try {
    endpointUrl.search = queryParameters;
    const response = await fetch(endpointUrl, options);
    printResponse(response);
  } catch (error) {
    printError(error);
  }
}
fetchAccessToken();

Authorization code access token

Use the code below to generate an authorization code access token using a refresh token.

Javascript (babel-node)
const endpointUrl = new URL('https://accounts.spotify.com/api/token');
const queryParameters = new URLSearchParams({
  grant_type: 'refresh_token',
  refresh_token: '{{REFRESH_TOKEN}}'
});
const required_ids = Buffer.from('{{CLIENT_ID}}:{{CLIENT_SECRET}}');
const encoded = required_ids.toString('base64');
headerParameters = {
    'Content-Type': 'application/x-www-form-urlencoded',
    'Authorization': 'Basic '+encoded
}
const options = {
  method: 'POST',
  headers: headerParameters
};
async function refreshAccessToken() {
  try {
    endpointUrl.search = queryParameters;
    const response = await fetch(endpointUrl, options);
    printResponse(response);
  } catch (error) {
    printError(error);
  }
}
refreshAccessToken();
