List signer changes
GET/signers/{id}/changes●Retrieve the change history of a signer by its handle or LUID.
Each change contains a complete snapshot of the record at that
point in time, the action performed (create, update, or
drop), and a timestamp. Changes are returned newest first.
After a record is deleted, its change history remains accessible but must be queried using the record's LUID instead of its handle.
Usage Examples
curl -X GET "http://localhost:3000/v2/signers/<HANDLE>/changes" \ -H "x-ledger: <YOUR LEDGER HANDLE>"{
