getrawtransaction - Zcash

Example code for the getrawtransaction JSON-RPC method. Сomplete guide on how to use the getrawtransaction JSON-RPC method in GetBlock.io Web3 documentation.

This method returns transaction data by txid. Verbosity 0 returns the raw serialized hex-encoded transaction bytes; verbosity 1 returns a decoded JSON object with all transaction fields, including transparent inputs/outputs and shielded pool data. Note that shielded transaction details are limited to what's on-chain — the actual amounts and recipients of shielded transactions are hidden by design.

Parameters

Parameter	Type	Required	Description
txid	string	Yes	32-byte transaction ID (hex-encoded)
verbose	integer	No	0 = raw hex, 1 = decoded JSON. Default 0
