My Question or Issue

Pawsitively delighted to see you vectorspace!
The preview_url parameter in the response data from the Spotify API's GET /albums/{id}/tracks endpoint is a URL that allows you to preview a 30-second snippet of a track.

To access the preview_url parameter for a specific track in an album, you can make a GET request to the GET /albums/{id}/tracks endpoint, where {id} is the unique identifier for the album. You will receive a JSON response containing an array of track objects, each of which will include a preview_url parameter if it is available.

Here's an example of how you can use the Spotify API's GET /albums/{id}/tracks endpoint to get the preview_url parameter for the tracks of an album using the Python requests library:

import requests

# Set up the endpoint URL and parameters
url = "https://api.spotify.com/v1/albums/{id}/tracks"
headers = {
    "Authorization": "Bearer {your_access_token}",
    "Content-Type": "application/json"
}
params = {
    "market": "US"
}

# Make the request to the API
response = requests.get(url.format(id="{album_id}"), headers=headers, params=params)

# Check if the request was successful
if response.status_code == 200:
    # Get the JSON data from the response
    data = response.json()

    # Loop through the tracks in the album
    for track in data['items']:
        # Check if the track has a preview URL
        if 'preview_url' in track:
            # Print the preview URL for the track
            print(f"Preview URL for {track['name']}: {track['preview_url']}")
else:
    print(f"Request failed with status code {response.status_code}")

Make sure to replace {your_access_token} with your actual Spotify access token and {album_id} with the unique identifier for the album you want to get the tracks for. Also note that the market parameter is optional, and you can remove it if you want to get results for all available markets.

Don't leave me in the doghouse, keep me informed!

I think this is a known issue and also related to my Github issue I posted today; https://github.com/spotify/spotify-web-api-ts-sdk/issues/86

Seems like the Client Credentials flow for backend applications tends to provide an preview_url with null value. No clue why Spotify does this. Searched everywhere like crazy, but can't find any working solution..

I historically used a `grant_type: "refresh_token"` to get my playlists, and they all had `preview_url` for my market.
However, if I use `grant_type: client_credentials` instead, some of these same exact tracks **do not** have `preview_url` even when the market is set to my country in the params.
Nonetheless, it's frustrating. In having to use the refresh token process, I have to do more work to just return public playlists only.
More frustrating, Spotify's definition of "Add to profile" doesn't mean the same thing as make `public`. 

That's why using `grant_type: client_credentials` had made fetching my actual public playlists easier, but with one huge drawback – missing preview urls.
