My Question or Issue

I have a Python script that utilises the `https://api.spotify.com/v1/me/playlists` endpoint. However, the request only returns some of my created playlists and non of my followed playlists. The documentation says it should return all playlists in my library. Also, when I use the 'try it' feature on Spotify's website, it works perfectly fine. I've made sure I have the right scopes, the user ID is correct and even made sure my playlists are public (not that it should matter). Here is my code calling the function:

def getUsersPlaylists(self, offset): 
        headers = {
            "Authorization" : f"Bearer {self.access_token}"
        }
        endpoint = 'https://api.spotify.com/v1/me/playlists?offset=' + str(offset) + '&limit=50'
        return requests.get(endpoint, headers=headers).json()

It should be returning 47 playlists (I have 47 in my library), but it only returns 19 and it doesn't provide a 'next' URL with a next set of playlists either. Thanks to anyone who can help 🙂

Client credentials only work with playlists that are public and are displayed on your/someone's profile.

Thanks for the reply. I  have made sure that the playlists that aren't showing are public. However, they still don't show. What do you mean by 'displayed on your/someone's profile' - how can I ensure this?

[ImOnABus]

Never mind. I figured out what it means by 'displayed on profile'. However, why does it require this? I'm using the 'user-read-private' scope and it works perfectly fine on the 'try me' feature in the Spotify for Developers documentation here: https://developer.spotify.com/documentation/web-api/reference/get-a-list-of-current-users-playlists

To use that scope, you'll need an Access Token generated by your app using the Authorization Code Flow or the Authorization Code with PKCE Flow.

[ImOnABus]

I'm already using the authorisation flow. Why would it still not be working?

[Ximzend]

Do you use the required Scopes? If so, I don't have a clue where the problem lies.

[ImOnABus]

Ahhh I can't believe I made this mistake. I was using the 

user-read-private and playlist-read-collaborative scopes, but not the playlist-read-private scope. Using this scope fixed the problem. Thanks 🙂
