Fortunately, I sent the request from the beginning and received the token in the form of JSON. By the way, how can I use the API using the token I received now?
The status of 401 is the result of the api requested by axios.get().
Below is the response I received after running step 3.
{
"access_token": "access_token",
"expires_in": 14376,
"refresh_token": "refresh_token",
"scope": [
"viewing_activity_read"
],
"token_type": "bearer"
}
