Usage

​
1. Exchange Authorization Code for Token

After the user approves on the consent page, your redirect_uri receives a code parameter. Exchange it for an access token: 
curl --request POST \
  --url https://app.profy.cn/oauth/token \
  --header 'Content-Type: application/json' \
  --data '{
    "grant_type": "authorization_code",
    "code": "auth-code-from-callback",
    "redirect_uri": "https://your-app.com/callback",
    "client_id": "your-app-uuid",
    "client_secret": "your-app-secret"
  }'

​
2. Refresh an Expired Token

Access tokens expire after 1 hour. Use the refresh token to get a new token pair: 
curl --request POST \
  --url https://app.profy.cn/oauth/token \
  --header 'Content-Type: application/json' \
  --data '{
    "grant_type": "refresh_token",
    "refresh_token": "your-refresh-token",
    "client_id": "your-app-uuid",
    "client_secret": "your-app-secret"
  }'
Refresh tokens are rotated on each use — the old token is immediately invalidated. Always save the new refresh_token from the response.
