Retrieves a contact.
When a source contact is merged with a target contact, the source contact is deleted. When calling Get Contact for a merged contact, you can use the source or target contact ID. In both bases, the target contact is returned.
This is supported only when calling Get Contact, and only for merged contacts. Deleted source contact IDs are not supported on any other endpoint.
Members are typically associated with a contact, each having a distinct member and contact ID. When passing the ID as a parameter, avoid presuming the IDs are identical since they represent separate entities.
You can only call this method when authenticated as a Wix app or Wix user identity.
