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/gracenoah/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 Available endpoints: /abci_info /dump_consensus_state /genesis /net_info /num_unconfirmed_txs /status /health /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=_ /dial_persistent_peers?persistent_peers=_ /subscribe?event=_ /tx?hash=_&prove=_ /unsafe_start_cpu_profiler?filename=_ /unsafe_write_heap_profile?filename=_ /unsubscribe?event=_ ```

<aside class="notice">Returns at most 20 items.</aside>
func BroadcastEvidence ¶ added in v0.32.6
func BroadcastEvidence(ctx *rpctypes.Context, ev types.Evidence) (*ctypes.ResultBroadcastEvidence, error)
Broadcast evidence of the misbehavior.
```shell curl 'localhost:26657/broadcast_evidence?evidence={amino-encoded DuplicateVoteEvidence}' ```

if err != nil { // handle error }
defer client.Stop() res, err := client.BroadcastEvidence(&types.DuplicateVoteEvidence{PubKey: ev.PubKey, VoteA: ev.VoteA, VoteB: ev.VoteB}) ```
> The above command returns JSON structured like this:
```json ```
| Parameter | Type | Default | Required | Description | |-----------+----------------+---------+----------+-----------------------------| | evidence | types.Evidence | nil | true | Amino-encoded JSON evidence |
func BroadcastTxAsync ¶
Returns right away, with no response. Does not wait for CheckTx nor DeliverTx results.
If you want to be sure that the transaction is included in a block, you can subscribe for the result using JSONRPC via a websocket. See https://tendermint.com/docs/app-dev/subscribing-to-events-via-websocket.html If you haven't received anything after a couple of blocks, resend it. If the same happens again, send it to some other node. A few reasons why it could happen:
1. malicious node can drop or pretend it had committed your tx 2. malicious proposer (not necessary the one you're communicating with) can drop transactions, which might become valid in the future (https://github.com/gracenoah/tendermint/issues/3322) 3. node can be offline
Please refer to https://tendermint.com/docs/tendermint-core/using-tendermint.html#formatting for formatting/encoding rules.
```shell curl 'localhost:26657/broadcast_tx_async?tx="123"' ```
```go client := client.NewHTTP("tcp://0.0.0.0:26657", "/websocket") err := client.Start()
if err != nil { // handle error }
defer client.Stop() result, err := client.BroadcastTxAsync("123") ```
> The above command returns JSON structured like this:
```json
{ "error": "", "result": { "hash": "E39AAB7A537ABAA237831742DCE1117F187C3C52", "log": "", "data": "", "code": "0" }, "id": "", "jsonrpc": "2.0" }
```
### Query Parameters
| Parameter | Type | Default | Required | Description | |-----------+------+---------+----------+-----------------| | tx | Tx | nil | true | The transaction |
func BroadcastTxCommit ¶
Returns with the responses from CheckTx and DeliverTx.
IMPORTANT: use only for testing and development. In production, use BroadcastTxSync or BroadcastTxAsync. You can subscribe for the transaction result using JSONRPC via a websocket. See https://tendermint.com/docs/app-dev/subscribing-to-events-via-websocket.html
CONTRACT: only returns error if mempool.CheckTx() errs 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.
Please refer to https://tendermint.com/docs/tendermint-core/using-tendermint.html#formatting for formatting/encoding rules.
```shell curl 'localhost:26657/broadcast_tx_commit?tx="789"' ```

```
func Subscribe ¶
Subscribe for events via WebSocket.
To tell which events you want, you need to provide a query. query is a string, which has a form: "condition AND condition ..." (no OR at the moment). condition has a form: "key operation operand". key is a string with a restricted set of possible symbols ( \t\n\r\\()"'=>< are not allowed). operation can be "=", "<", "<=", ">", ">=", "CONTAINS". operand can be a string (escaped with single quotes), number, date or time.
Examples:
tm.event = 'NewBlock' # new blocks tm.event = 'CompleteProposal' # node got a complete proposal tm.event = 'Tx' AND tx.hash = 'XYZ' # single transaction tm.event = 'Tx' AND tx.height = 5 # all txs of the fifth block tx.height = 5 # all txs of the fifth block
Tendermint provides a few predefined keys: tm.event, tx.hash and tx.height. Note for transactions, you can define additional keys by providing events with DeliverTx response.
import ( abci "github.com/gracenoah/tendermint/abci/types" "github.com/gracenoah/tendermint/libs/pubsub/query" ) abci.ResponseDeliverTx{ Events: []abci.Event{ { Type: "rewards.withdraw", Attributes: cmn.KVPairs{ cmn.KVPair{Key: []byte("address"), Value: []byte("AddrA")}, cmn.KVPair{Key: []byte("source"), Value: []byte("SrcX")}, cmn.KVPair{Key: []byte("amount"), Value: []byte("...")}, cmn.KVPair{Key: []byte("balance"), Value: []byte("...")}, }, }, { Type: "rewards.withdraw", Attributes: cmn.KVPairs{ cmn.KVPair{Key: []byte("address"), Value: []byte("AddrB")}, cmn.KVPair{Key: []byte("source"), Value: []byte("SrcY")}, cmn.KVPair{Key: []byte("amount"), Value: []byte("...")}, cmn.KVPair{Key: []byte("balance"), Value: []byte("...")}, }, }, { Type: "transfer", Attributes: cmn.KVPairs{ cmn.KVPair{Key: []byte("sender"), Value: []byte("AddrC")}, cmn.KVPair{Key: []byte("recipient"), Value: []byte("AddrD")}, cmn.KVPair{Key: []byte("amount"), Value: []byte("...")}, }, }, }, }
All events are indexed by a composite key of the form {eventType}.{evenAttrKey}. In the above examples, the following keys would be indexed:
- rewards.withdraw.address
- rewards.withdraw.source
- rewards.withdraw.amount
- rewards.withdraw.balance
- transfer.sender
- transfer.recipient
- transfer.amount
Multiple event types with duplicate keys are allowed and are meant to categorize unique and distinct events. In the above example, all events indexed under the key `rewards.withdraw.address` will have the following values stored and queryable:
- AddrA
- AddrB
To create a query for txs where address AddrA withdrew rewards:
query.MustParse("tm.event = 'Tx' AND rewards.withdraw.address = 'AddrA'")
To create a query for txs where address AddrA withdrew rewards from source Y:
query.MustParse("tm.event = 'Tx' AND rewards.withdraw.address = 'AddrA' AND rewards.withdraw.source = 'Y'")
To create a query for txs where AddrA transferred funds:
query.MustParse("tm.event = 'Tx' AND transfer.sender = 'AddrA'")
The following queries would return no results:
query.MustParse("tm.event = 'Tx' AND transfer.sender = 'AddrZ'") query.MustParse("tm.event = 'Tx' AND rewards.withdraw.address = 'AddrZ'") query.MustParse("tm.event = 'Tx' AND rewards.withdraw.source = 'W'")
See list of all possible events here https://godoc.org/github.com/gracenoah/tendermint/types#pkg-constants
For complete query syntax, check out https://godoc.org/github.com/gracenoah/tendermint/libs/pubsub/query.
```go import "github.com/gracenoah/tendermint/types"

if err != nil { // handle error }
defer client.Stop() ctx, cancel := context.WithTimeout(context.Background(), 1 * time.Second) defer cancel() query := "tm.event = 'Tx' AND tx.height = 3" txs, err := client.Subscribe(ctx, "test-client", query)
if err != nil { // handle error }
go func() { for e := range txs { fmt.Println("got ", e.Data.(types.EventDataTx)) } }()
```
