Refresh Access Token

REST APIs Common OAuthRefresh Access Token

Refresh Access Token

POSThttps://exchange.gemini.com/auth/token

The access token you receive will be relatively short-lived (default 24 hours). Once an access token has expired you can use your refresh token to generate a new access token. Refresh tokens never expire, however they are one-time use only — your request for a new access token will also return a new refresh token.
