Question

I am trying to do spotify login via the expo-auth-session on my expo app In the expo-auth-session doc, https://docs.expo.dev/guides/authentication/#spotify

I tried calling the refresh token endpoint using the authorization code that I got from the auth code flow, but it didn't work.

Answer 1

You can get refresh token by curl

curl -d client_id={CLIENT_ID} \
-d client_secret={CLIENT_SECRET} \
-d grant_type=authorization_code \
-d code={CODE} \
-d redirect_uri={REDIRECT_URI} \
https://accounts.spotify.com/api/token

Step 1 - create your application

Create your App in Spotify Developer Dashboard

Get Client ID, Client Secret and add redirect URIs

Step 2 - Get code

https://accounts.spotify.com/authorize?response_type=code&client_id={your client id}&scope=user-read-email&redirect_uri={your redirect URL, mine is http://localhost:3000}

Browser will show code in the address control, copy the code part.

Step 3 - Get refresh

Get refresh code by curl from terminal

curl -d client_id={your client it} \
-d client_secret={your client secret} \
-d grant_type=authorization_code \
-d code={code from Step #2} \
-d redirect_uri=http://localhost:3000 \
https://accounts.spotify.com/api/token | jq

You can get the refresh token

{
  "access_token": "BQC...V-1"
  "token_type": "Bearer",
  "expires_in": 3600,
  "refresh_token": "AQA...6twR
  "scope": "user-read-email"
}
