};First, we need to create a Spotify application to give us credentials to authenticate with the API.
http://localhost:3000 as a redirect URI.All done! You now have a properly configured Spotify application and the correct credentials to make requests.
There are a variety of ways to authenticate with the Spotify API, depending on your application. Since we only need permission granted once, we'll use the Authorization Code Flow.
First, we'll have our application request authorization by logging in with whatever scopes we need.
Here's an example of what the URL might look like.
Swap out the client_id and scopes for your own.
https://accounts.spotify.com/authorize?client_id=8e94bde7dd
b84a1f7a0e51bf3bc95be8&response_type=code&redirect_uri=http
%3A%2F%2Flocalhost:3000&scope=user-read-currently-playing%20
user-top-readAfter authorizing, you'll be redirected back to your redirect_uri.
In the URL, there's a code query parameter. Save this value.
http://localhost:3000/callback?code=NApCCg..BkWtQNext, we'll need to retrieve the refresh token. You'll need to generate a Base 64 encoded string containing the client ID and secret from earlier. You can use this tool to encode it online. The format should be client_id:client_secret.
curl -H "Authorization: Basic <base64 encoded client_id:client_secret>"
-d grant_type=authorization_code -d code=<code> -d redirect_uri=http%3A
%2F%2Flocalhost:3000 https://accounts.spotify.com/api/tokenThis will return a JSON response containing a refresh_token. This token is valid indefinitely unless you revoke access, so we'll want to save this in an environment variable.
To securely access the API, we need to include the secret with each request. We also do not want to commit secrets to git. Thus, we should use an environment variable.
