getTransaction

An RPC method that retrieves a confirmed or finalized transaction by its base-58 signature, returning the full message (account keys, instructions, address lookup tables), pre- and post-balances, inner instructions, log messages, and compute units consumed. The maxSupportedTransactionVersion parameter must be set to 0 to decode versioned transactions that use address lookup tables; the method returns null if the transaction has been purged from the node's transaction status cache (default retention is around 2 days on most RPC providers).
