ConstructionMetadataRequest

A ConstructionMetadataRequest is utilized to get information required to construct a transaction. The Options object used to specify which metadata to return is left purposely unstructured to allow flexibility for implementers. Optionally, the request can also include an array of PublicKeys associated with the AccountIdentifiers returned in ConstructionPreprocessResponse.

Properties

Name	Type	Description	Required
network_identifier	NetworkIdentifier	The network_identifier specifies which network a particular object is associated with.	True
options	Object	Some blockchains require different metadata for different types of transaction construction (ex: delegation versus a transfer). Instead of requiring a blockchain node to return all possible types of metadata for construction (which may require multiple node fetches), the client can populate an options object to limit the metadata returned to only the subset required.	True
public_keys	[]PublicKey		False
