can't get Followed Artists - Client credentials authentication not allowed

[mi_sw]

I am trying to get Followed Artists:
https://developer.spotify.com/documentation/web-api/reference/get-followed

I am requesting Access Token:

CLIENT_ID=<client_id> &&\
CLIENT_SECRET=<client_secret> &&\
SCOPES=user-follow-read

curl -X POST "https://accounts.spotify.com/api/token" \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "grant_type=client_credentials&client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}&scope=${SCOPES}"

with generated Access Token I am trying to get followed artists:

TOKEN=<token>

curl -X GET \
--url 'https://api.spotify.com/v1/me/following?type=artist&limit=50' \
--header "Authorization: Bearer ${TOKEN}"

curl returns:

{
  "error" : {
    "status" : 400,
    "message" : "Client credentials authentication not allowed"
  }
}

what is wrong here?

"Since [the Client Credentials] flow does not include authorization, only endpoints that do not access user information can be accessed." - https://developer.spotify.com/documentation/web-api/tutorials/client-credentials-flow

[mi_sw]

you can get Access Token when making request in console (after you logged in):

https://developer.spotify.com/documentation/web-api/reference/get-followed

and use it later on (until TTL) with curl

BUT you can't generate your own AT.

You can get your own AT through another flow that is not the Client Credentials flow, listed on here: https://developer.spotify.com/documentation/web-api/concepts/authorization
