Field	Type	Rules	Description
success	boolean	-	Whether the request completed successfully.
data	RefreshTokenData	No additional properties	Response or event payload for this schema.
data.access_token	string	-	New seller-scoped access token.
data.refresh_token	string	-	New single-use refresh token.

meta.limit	integer	-	Maximum number of records returned in this response page.
meta.total	integer	-	Total number of records matching the request filters. Offset paging only — omitted during a cursor walk, where no total is computed.
