# 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 which contains its own set of documentation and tests.
|
|
See it here: https://github.com/tendermint/tendermint/tree/master/rpc/lib
|
|
|
|
## Configuration
|
|
|
|
RPC can be configured by tuning parameters under `[rpc]` table in the `$TMHOME/config/config.toml` file or by using the `--rpc.X` command-line flags.
|
|
|
|
Default rpc listen address is `tcp://0.0.0.0:26657`. To set another address, set the `laddr` config parameter to desired value.
|
|
CORS (Cross-Origin Resource Sharing) can be enabled by setting `cors_allowed_origins`, `cors_allowed_methods`, `cors_allowed_headers` config parameters.
|
|
|
|
## 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:26657/broadcast_tx_sync?tx="abc"'
|
|
```
|
|
|
|
> Response:
|
|
|
|
```json
|
|
{
|
|
"error": "",
|
|
"result": {
|
|
"hash": "2B8EC32BA2579B3B8606E42C06DE2F7AFA2556EF",
|
|
"log": "",
|
|
"data": "",
|
|
"code": "0"
|
|
},
|
|
"id": "",
|
|
"jsonrpc": "2.0"
|
|
}
|
|
```
|
|
|
|
## JSONRPC/HTTP
|
|
|
|
JSONRPC requests can be POST'd to the root RPC endpoint via HTTP (e.g. `http://localhost:26657/`).
|
|
|
|
```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:26657/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:26657'
|
|
```
|
|
|
|
> Response:
|
|
|
|
```plain
|
|

|
|
