Refresh Token Grant Type

The Refresh Token grant type uses the refresh token to generate a new token.

Note

Refresh tokens are single use only so cannot be reused, and when they are used they also invalidate the token they are associated with.

Request new token

curl -X POST \
  https://tyk.cloud.tyk.io/oauth-api/oauth/token/ \
