Quick-start

Send users here to begin authorization:

GET https://server.ctksystem.com/accountsystem/oauth/authorize
  ?client_id=YOUR_CLIENT_ID
  &redirect_uri=YOUR_REDIRECT_URI
  &state=RANDOM_STATE

Exchange the returned code for tokens:

POST https://server.ctksystem.com/accountsystem/oauth/token
Content-Type: application/json

{
  "grant_type":    "authorization_code",
  "code":          "<code from redirect>",
  "client_id":     "YOUR_CLIENT_ID",
  "client_secret": "YOUR_CLIENT_SECRET",
  "redirect_uri":  "YOUR_REDIRECT_URI"
}

Fetch the user's profile with the access token:

GET https://server.ctksystem.com/accountsystem/oauth/userinfo
Authorization: Bearer <access_token>
