The getrawtransaction RPC method in Bitcoin Core allows users to retrieve a raw transaction from the blockchain by its transaction ID. This method is part of the Bitcoin Core JSON-RPC API, which enables programmatic interaction with the Bitcoin network. To use getrawtransaction, you must have a running Bitcoin Core node with RPC server enabled and proper authentication configured.

When calling getrawtransaction, you provide the transaction ID （txid） as a required parameter. Optionally, you can set a verbose flag to return a decoded transaction object instead of the raw hex string. This is useful for extracting detailed information such as inputs, outputs, and confirmations. For example, with verbose set to true, the response includes the transaction\“s version, locktime, and vin/vout arrays.

It\“s important to note that getrawtransaction only works for transactions in the node\“s mempool or blockchain. If the transaction is not found, an error is returned. This method is essential for developers building applications that need to analyze transaction data, such as wallets, explorers, or auditing tools. Always ensure your node is synced to access the latest transactions.
