To make the customer's login process easier, the store may use an access token to keep the client logged in for a period of time. Access tokens, on the other hand, may only be valid for a short amount of time for security reasons. A refresh token is used to "refresh" the access token once it has expired. This endpoint refresh token allows a client to receive new access tokens without requiring them to log in again.
TIP
The refresh endpoint has been implemented in the Login Web Component, and It's all setup to save developer's time and effort.
