DeleteDIDRequest

Field	Type	Description
did	string	The id of the identity to delete.
origin_volt	string	Force delete of all DIDs owned by the specified Volt.
key_passphrase	string	Optional passphrase of the DID controller key. Required if the key is encrypted.

DeleteDIDResponse

Field	Type	Description
status	Status	Details of any error that occurred on the call.

GetDIDRegistryUpdatesRequest

Field	Type	Description
since_id	uint64	The id of the last update received. All updates since this id will be returned, limited to the maximum number of updates specified in the request. To fully synchronise, clients should continue calling this method until the response contains no updates. If this is the first call, then this should be set to 0.
max_updates	uint32	The maximum number of updates to return, defaults to 1000.
origin_volt	string	Filter by origin volt.

GetDIDRegistryUpdatesResponse

Field	Type	Description
status	Status	Details of any error that occurred on the call.
update	DIDRegistryUpdate repeated	The updates.

ImportCredentialRequest

Field	Type	Description
id	string	Optional id of existing credential to import into. If not specified, a new credential will be created.
json	string	The JSON representation of the credential.

Field	Type	Description
status	Status	Details of any error that occurred on the call.
id	string	The id assigned to the credential.

ParseCredentialRequest

Field	Type	Description
verifiable_presentation	VerifiablePresentation	A presentation of the verifiable credential. The presentation doesn't need to be signed, but if it is, the signature will be verified using the public key provided in the request.
url	string	A URL to a verifiable credential. Not yet implemented.
presentation_public_key	string	Optional public key to use to verify the presentation signature.

ParseCredentialResponse

Field	Type	Description
status	Status	Details of any error that occurred on the call.

RegisterDIDDocumentRequest

Field	Type	Description
create	bool
did_update	DIDRegistryUpdate	The DID document to save.
update_signature	string	When updating an existing DID document, it is necessary to include a signature of the document JSON, signed by the DID document's current owner. This is different from the proof contained in the DID document itself.

RegisterDIDDocumentResponse

Field	Type	Description
status	Status	Details of any error that occurred on the call.
did_document	DIDRegistryUpdate

ResolveDIDRequest

Field	Type	Description
did	string	The DID to resolve.

id	string	The id assigned to the credential.
json	string	The JSON representation of the credential.

SearchDIDRegistryRequest

Field	Type	Description
did_filter	string	Filter by DID itself. This is a prefix match, so searching for 'did:volt:123' will match 'did:volt:1234'. You can also exclude the 'did:volt:' prefix.
description_filter	string	Filter by the (optional) description attached to the DID document. This will match any DID document whose description contains the specified string, for example 'John' will match 'John Smith', 'Elton John' and 'Jasper Johns-Frederick'.
origin_filter	string	Filter by the origin Volt. This will match any DID document whose origin Volt matches exactly the given DID.
page_number	uint32	The page number to retrieve, defaults to 1.
page_size	uint32	The number of results per page, defaults to 100.
