You can't play a song by curl command. Your try method is Client Credentials Flow.
This method can get artist, album, and song information.
The play of a song needs the Authorization Code Flow. It can do users play songs, and get user information as related user APIs.
It should get the token by "redirect_URI".

Code Overview
Demo code - using express on node.js
Save as play-song.js
You need to launch the Spotify App or logged in to Spotify by the browser.
const axios = require('axios')
const express = require('express')
const cors = require('cors')
const app = express()
app.use(cors())
// for raw JSON of Body
app.use(express.json())
const REDIRECT_URI = '<your redirect URL>' // mine is http://localhost:3000/callback
const CLIENT_ID = '<your client id>'
const CLIENT_SECRET = '<your client secret>'
const SCOPE = ['playlist-modify-private', 'user-read-currently-playing', 'user-read-playback-state', 'user-modify-playback-state']
app.get("/login", (request, response) => {
const redirect_url = `https://accounts.spotify.com/authorize?response_type=code&client_id=${CLIENT_ID}&scope=${SCOPE}&state=123456&redirect_uri=${REDIRECT_URI}&prompt=consent`
response.redirect(redirect_url);
})
app.get("/callback", async (request, response) => {
const code = request.query["code"]
await axios.post(
url = 'https://accounts.spotify.com/api/token',
data = new URLSearchParams({
'grant_type': 'authorization_code',
'redirect_uri': REDIRECT_URI,
'code': code
}),
config = {
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},
params: {
'grant_type': 'client_credentials'
},
auth: {
username: CLIENT_ID,
password: CLIENT_SECRET
}
})
.then(resp1 => {
axios.get(
url = 'https://api.spotify.com/v1/me/player/devices',
config = {
headers: {
'Accept-Encoding': 'application/json',
Authorization: `Bearer ${resp1.data.access_token}`
}
}
).then(resp2 => {
const device_id = resp2.data.devices[0].id
const track_id = '7pKfPomDEeI4TPT6EOYjn9' // Imagine-Remastered 2010
const access_token = resp1.data.access_token;
axios.put(`https://api.spotify.com/v1/me/player/play?device_id=${device_id}`, {
uris: [`spotify:track:${track_id}`]
}, {
headers: {
'Authorization': `Bearer ${access_token}`,
'Content-Type': 'application/json'
}
})
.then(data => {
response.send(JSON.stringify({"device id": device_id}))
})
.catch(error => {
console.error(error)
});
})
});
})
// use your <redirect URL>'s port
app.listen(3000, () => { console.log("Listening on : 3000") })
install dependencies
npm install axios express cors
Run it
node play-song.js
Then open browser, access this URL
localhost:3000/login
Remember the port number should be use your port number in your dashboard
