Hello,

I assume I'm making a newbie mistake, but can't seem to see where the issue lies.

1. I made a successful request to https://www.strava.com/api/v3/oauth/token
where I receive the following response

{
token_type: 'Bearer',
expires_at: 1695548372,
expires_in: 20715,
refresh_token: '123abc', // replacing real values
access_token: '456def', // replacing real values
athlete: {
      id: ...,
   }
}
2. I then take the access_token to get activity like:
curl https://www.strava.com/api/v3/athlete/activities -H “Authorization: Bearer 456def”

where I then get the following error: 
{"message":"Authorization Error","errors":r{"resource":"Athlete","field":"access_token","code":"invalid"}]}curl: (6) Could not resolve host: Bearer
curl: (6) Could not resolve host: 456def”

I also have a follow up question, what is the difference between the access token I recieve when authorizing via OAuth (above query) and the access token I have in my developer settings on my Strava developer profile?
