# Get Access Token v3

`POST /token/v3`

Either:
  1) Exchanges an authorization_code for an access_token, or
  2) Exchanges a refresh_token for an access_token.
When exchanging a refresh_token for an access_token, also invalidates existing refresh_token and generates a new refresh_token.
See [Refresh Tokens](https://docs.developer.yelp.com/docs/refresh-tokens) for how this works
