# `eth_getTransactionByBlockHashAndIndex`

Returns information about a transaction given block hash and transaction index position. This method uses [150 credits](/services/get-started/pricing/) from your daily balance.

## Parameters[​](#parameters "Direct link to Parameters")

- `block hash`: [_Required_] A string representing the hash (32 bytes) of a block.
- `transaction index position`: [_Required_] A hexadecimal of the integer representing the position in the block.

## Returns[​](#returns "Direct link to Returns")

A transaction object, or null when no transaction was found. The transaction object will consist of the following keys and their values:

- `accessList`: [_optional_] A list of addresses and storage keys accessed by the transaction. See [access list transactions](/services/concepts/transaction-types/#access-list-transactions).
- `blockHash`: 32 bytes. A hash of the block including this transaction. `null` when it's pending.
- `blockNumber`: The number of the block including this transaction. `null` when it's pending.
- `chainID`: [_optional_] chain ID specifying the network. Returned only for [EIP-1559 transactions](/services/concepts/transaction-types/#eip-1559-transactions).
- `from`: 20 bytes. The address of the sender.
- `gas`: Gas provided by the sender.
- `gasPrice`: Gas price provided by the sender in wei.
- `hash`: 32 bytes. The hash of the transaction.
- `input`: The data sent along with the transaction.
- `maxPriorityFeePerGas`: [_optional_] Maximum fee, in wei, the sender is willing to pay per gas above the base fee. See [EIP-1559 transactions](/services/concepts/transaction-types/#eip-1559-transactions).
- `maxFeePerGas`: [_optional_] Maximum total fee (base fee + priority fee), in wei, the sender is willing to pay per gas. See [EIP-1559 transactions](/services/concepts/transaction-types/#eip-1559-transactions).
- `nonce`: The number of transactions made by the sender prior to this one.
- `r`: 32 bytes. The ECDSA signature `r`.
- `s`: 32 bytes. The ECDSA signature `s`.
- `to`: 20 bytes. The address of the receiver. `null` when it's a contract creation transaction.
- `transactionIndex`: The transaction's index position in the block, in hexadecimal. `null` when it's pending.
- `type`: The [transaction type](/services/concepts/transaction-types/).
- `v`: The ECDSA recovery ID.
- `value`: The value transferred in wei.
- `yParity`: [_optional_] Parity (`0x0` for even, `0x1` for odd) of the y-value of a [secp256k1](https://eips.ethereum.org/EIPS/eip-2098#:~:text=A%20secp256k1%20signature%20is%20made%20up%20of%203%20parameters%2C%20r%2C%20s%20and%20yParity.) signature.
