My Question or Issue
Hi. I try to build a litte C# Script to play a Song with the Spotify-API.
I am logged in as a member of an family premium account and i have a login-token to call the play-function.
First i try to login with my credentials. It works:
using (HttpClient client = new HttpClient())
{
var requestBody = new Dictionary<string, string>
{
{ "grant_type", "client_credentials" },
{ "client_id", ClientId },
{ "client_secret", ClientSecret }
};
HttpResponseMessage response = await client.PostAsync("https://accounts.spotify.com/api/token", new FormUrlEncodedContent(requestBody));
...
I get a response and my token to use:
response StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
x-request-id: bbed5d37-fd21-4c0a-9d50-069361731a7a

}
Next i try to make a search with my token and it works fine:
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue("Bearer", AccessToken);
string encodedQuery = Uri.EscapeDataString(query);
var response = await client.GetAsync($"{ApiBaseUrl}/search?q={encodedQuery}&type=track&limit=5");
...
search response StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

}
Then i try to play an existing song and get an 403-error:
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue("Bearer", AccessToken);
var requestData = new
{
uris = new[] { trackUri }
};
var json = System.Text.Json.JsonSerializer.Serialize(requestData);
var content = new StringContent(json, Encoding.UTF8, "application/json");
var response = await client.PutAsync($"{ApiBaseUrl}/me/player/play", content);
...
play response StatusCode: 403, ReasonPhrase: 'Forbidden', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

}
Why do i get this error? I am logged in with a token from a family-premium user.
Thanks for your help.
