## Introduction

This is a list of the monero-wallet-rpc calls, their inputs and outputs, and examples of each. The program monero-wallet-rpc replaced the rpc interface that was in simplewallet and then monero-wallet-cli.

All monero-wallet-rpc methods use the same JSON RPC interface. For example:

    IP=127.0.0.1
    PORT=18082
    METHOD="make_integrated_address"
    PARAMS="{\"payment_id\":\"1234567890123456789012345678900012345678901234567890123456789000\"}"
    curl \
        -X POST http://$IP:$PORT/json_rpc \
        -d '{"jsonrpc":"2.0","id":"0","method":"'$METHOD'","params":'"$PARAMS"'}' \
        -H 'Content-Type: application/json'

If the monero-wallet-rpc was executed with the `--rpc-login` argument as `username:password`, then follow this example:

    IP=127.0.0.1
    PORT=18082
    METHOD="make_integrated_address"
    PARAMS="{\"payment_id\":\"1234567890123456789012345678900012345678901234567890123456789000\"}"
    curl \
        -u username:password --digest \
        -X POST http://$IP:$PORT/json_rpc \
        -d '{"jsonrpc":"2.0","id":"0","method":"'$METHOD'","params":'"$PARAMS"'}' \
        -H 'Content-Type: application/json'

Note: "atomic units" refer to the smallest fraction of 1 XMR according to the monerod implementation. **1 XMR = 1e12 atomic units.**

      "unlock_time": 0
    }]
  }
}


### get_bulk_payments

Get a list of incoming payments using a given payment id, or a list of payments ids, from a given height. This method is the preferred method over `get_payments` because it has the same functionality but is more extendable. Either is fine for looking up transactions by a single payment ID.

Inputs:

* *payment_ids* - array of: string
 * *min_block_height* - unsigned int; The block height at which to start looking for payments.

Outputs:

* *payments* - list of:

{:.cli-code}
<span style="color: cyan;">[ monero->~ ]$</span> curl -X POST http://127.0.0.1:18082/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"get_bulk_payments","params":{"payment_ids":["4279257e0a20608e25dba8744949c9e1caff4fcdafc7d5362ecf14225f3d9030"],"min_block_height":990000}}' -H 'Content-Type: application/json'
