If you are using the authorization code flow, this information is provided in the redirection query parameters. The following example URLs show redirects to http://myapplication.com in cases where the user either accepts or rejects authorization.
Definitions
- access_token – Implicit grants only. If you are using the implicit grant flow, this key contains a valid access token you can use to access the REST API on behalf of the authorizing user. Go to Authentication for instructions on using an access token to access the REST API.
- code – Authorization code grants only. If you are using the authorization code flow, this parameter contains an authorization code you can use to exchange for an access token and refresh token. The authorization code expires in ten minutes and can only be used once. Go to Authorization Code for instructions on obtaining an access token.
- token_type – Implicit grants only. The only supported type is bearer.
- state – The state you provided in the authorization request. You should verify that this value matches the state you provided earlier.
