We would like to confirm the expiration date of the refresh token.
1.
Do refresh tokens have an expiration date?
"3.1.1 V1 Authentication" states that refresh tokens also have an expiration date, but we could not find any response item in the document that indicates the expiration date of the refresh token, like the 'expires_in' of the access token. If an expiration date is set, is there a way to obtain that information before the expiration date?
2.
When executing an authentication API using a refresh token, is the expiration date provided appropriately?
"3.1.4 V1 Authentication Response" also describes the response when 'grant_type=refresh_token' is specified, but 'expires_in' is clearly stated as the validity period of the access token.
Is the expiration date (validity period) of the refresh token provided as some kind of response?
