# Get block transactions (extended)
> Returns full transaction objects for all transactions in a specific block. Each transaction includes complete data: inbound and outbound messages, fees, state changes, and BoC-encoded raw data. Use `count` to limit results and `after_lt`/`after_hash` for pagination when `incomplete` is true.

info:
title: TON HTTP API C++
description: >
This API enables HTTP access to TON blockchain - getting accounts and
wallets information, looking up blocks and transactions, sending messages to
the blockchain, calling get methods of smart contracts, and more.
In addition to REST API, all methods are available through a JSON-RPC
endpoint with `method` equal to method name and `params` passed as a
dictionary.
The response contains a JSON object, which always has a boolean field `ok`
and either `error` or `result`. If `ok` equals true, the request was
successful and the result of the query can be found in the `result` field.
In case of an unsuccessful request, `ok` equals false and the error is
explained in the `error`.
API Key should be sent either as `api_key` query parameter or `X-API-Key`
header
