Documentation

Overview

Introduction

Tendermint supports the following RPC protocols:

* URI over HTTP * JSONRPC over HTTP * JSONRPC over websockets

Tendermint RPC is built using [our own RPC library](https://github.com/tendermint/tendermint/tree/master/rpc/lib). Documentation and tests for that library could be found at `tendermint/rpc/lib` directory.

## Configuration

Set the `laddr` config parameter under `[rpc]` table in the `$TMHOME/config.toml` file or the `--rpc.laddr` command-line flag to the desired protocol://host:port setting. Default: `tcp://0.0.0.0:46657`.

## Arguments

Arguments which expect strings or byte arrays may be passed as quoted strings, like `"abc"` or as `0x`-prefixed strings, like `0x616263`.

## URI/HTTP

```bash curl 'localhost:46657/broadcast_tx_sync?tx="abc"' ```

> Response:

```json

{
	"error": "",
	"result": {
		"hash": "2B8EC32BA2579B3B8606E42C06DE2F7AFA2556EF",
		"log": "",
		"data": "",
		"code": 0
	},
	"id": "",
	"jsonrpc": "2.0"
}

```

The first entry in the result-array (`96`) is the method this response correlates with. `96` refers to "ResultTypeBroadcastTx", see [responses.go](https://github.com/tendermint/tendermint/blob/master/rpc/core/types/responses.go) for a complete overview.

## JSONRPC/HTTP

JSONRPC requests can be POST'd to the root RPC endpoint via HTTP (e.g. `http://localhost:46657/`).

```json

{
	"method": "broadcast_tx_sync",
	"jsonrpc": "2.0",
	"params": [ "abc" ],
	"id": "dontcare"
}

```

## JSONRPC/websockets

JSONRPC requests can be made via websocket. The websocket endpoint is at `/websocket`, e.g. `localhost:46657/websocket`. Asynchronous RPC functions like event `subscribe` and `unsubscribe` are only available via websockets.

## More Examples

See the various bash tests using curl in `test/`, and examples using the `Go` API in `rpc/client/`.

## Get the list

An HTTP Get request to the root RPC endpoint shows a list of available endpoints.

```bash curl 'localhost:46657' ```

> Response:

```plain Available endpoints: /abci_info /dump_consensus_state /genesis /net_info /num_unconfirmed_txs /status /unconfirmed_txs /unsafe_flush_mempool /unsafe_stop_cpu_profiler /validators

Endpoints that require arguments: /abci_query?path=_&data=_&prove=_ /block?height=_ /blockchain?minHeight=_&maxHeight=_ /broadcast_tx_async?tx=_ /broadcast_tx_commit?tx=_ /broadcast_tx_sync?tx=_ /commit?height=_ /dial_seeds?seeds=_ /subscribe?event=_ /tx?hash=_&prove=_ /unsafe_start_cpu_profiler?filename=_ /unsafe_write_heap_profile?filename=_ /unsubscribe?event=_ ```

func BroadcastTxCommit

func BroadcastTxCommit(tx types.Tx) (*ctypes.ResultBroadcastTxCommit, error)

CONTRACT: only returns error if mempool.BroadcastTx errs (ie. problem with the app) or if we timeout waiting for tx to commit. If CheckTx or DeliverTx fail, no error will be returned, but the returned result will contain a non-OK ABCI code.

```shell curl 'localhost:46657/broadcast_tx_commit?tx="789"' ```

```go client := client.NewHTTP("tcp://0.0.0.0:46657", "/websocket") result, err := client.BroadcastTxCommit("789") ```
