The handshake operation allows a registrar to accept or reject a registrar change/registrant transfer authorisation request.

<h:accept> element

The <h:accept> element is used to accept a registrar change/registrant transfer authorisation request. This element contains the following sub-elements:

• An <h:caseId> element specifying the case-id of the authorisation request.
  
• An optional <h:registrant> element specifying an account that the domains associated with the case should be placed on. Note that this is only applicable to registrar changes. A new account is created If this element is not given.
  

<h:reject> element

The <h:reject> element is used to reject a registrar change/registrant transfer authorisation request. This element contains the following sub-elements:

• An <h:caseId> element specifying the case-id of the authorisation request.

Example handshake accept request
