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 Tx ¶
Tx allows you to query the transaction results. `nil` could mean the transaction is in the mempool, invalidated, or was not sent in the first place.

```go client := client.NewHTTP("tcp://0.0.0.0:46657", "/websocket") tx, err := client.Tx([]byte("2B8EC32BA2579B3B8606E42C06DE2F7AFA2556EF"), true) ```
> The above command returns JSON structured like this:
```json
{ "error": "", "result": { "proof": { "Proof": { "aunts": [] }, "Data": "YWJjZA==", "RootHash": "2B8EC32BA2579B3B8606E42C06DE2F7AFA2556EF", "Total": 1, "Index": 0 }, "tx": "YWJjZA==", "tx_result": { "log": "", "data": "", "code": 0 }, "index": 0, "height": 52 }, "id": "", "jsonrpc": "2.0" }
```
Returns a transaction matching the given transaction hash.
### Query Parameters
| Parameter | Type | Default | Required | Description | |-----------+--------+---------+----------+-----------------------------------------------------------| | hash | []byte | nil | true | The transaction hash | | prove | bool | false | false | Include a proof of the transaction inclusion in the block |
### Returns
- `proof`: the `types.TxProof` object - `tx`: `[]byte` - the transaction - `tx_result`: the `abci.Result` object - `index`: `int` - index of the transaction - `height`: `int` - height of the block where this transaction was in
func TxSearch ¶
TxSearch allows you to query for multiple transactions results.
