As an example, let's call the method "hello" of a smart contract that simply stores "hello" messages.
The helloRockside contract is deployed at: 0x4FD167973185AD2a968339172A936641fD31F3CD on Ropsten network.
We will call the hello  method with "hello rockside" as parameter.
The data that represent this call is:
DATA: 0xa777d0dc0000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000000e68656c6c6f20726f636b73696465000000000000000000000000000000000000
To generate the ABI encoded data, we used Web3 as follows:
const Web3 = require('web3')
const web3 = new Web3()
​
const helloContractAddress = "0xFb428d37AcC708F37A40c8D95d723e1Aea49cc07"
const helloContractABI = [{"inputs":[{"internalType":"string","name":"helloMsg","type":"string"}],"name":"hello","outputs":[],"stateMutability":"nonpayable","type":"function"},{"inputs":[{"internalType":"uint256","name":"","type":"uint256"}],"name":"helloMessages","outputs":[{"internalType":"string","name":"","type":"string"}],"stateMutability":"view","type":"function"}]
​
var helloContract =  new web3.eth.Contract(helloContractABI, helloContractAddress)
const data = helloContract.methods.hello("hello rockside").encodeABI();
​
console.log("DATA: "+data);
Call Rockside Relay API
Pass in the URL the address of the destination contract (in our case the helloRockside contract), in the body specify the speed and the data.  For more infos, check our Relay API.
curl --request POST 'https://api.rockside.io/ethereum/ropsten/relay/0x4FD167973185AD2a968339172A936641fD31F3CD' \
--header 'Content-Type: application/json' \
--data '{"speed": "fast","data": "0xa777d0dc0000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000000e68656c6c6f20726f636b73696465000000000000000000000000000000000000"}'

You will get:
{
    "transaction_hash": "0x2968698cb90ec9d95f8656d28bb29593029c79bcd22b42dc6b9469cb03729e2a",
    "tracking_id": "01EA266P6PKN0ZY01P0Q6G7WR5"
}
Follow your transaction status
You can follow your transaction on Etherscan with the transaction_hash. But because Rockside is susceptible to replay a stuck transaction, this hash value can changes.
To keep track of your transaction - whatever happens to it - use the tracking_id as follow:
curl --request GET 'https://api.rockside.io/ethereum/ropsten/transactions/TX_TRACKING_ID'
You will get:

This example run on Ropsten. For Mainnet you will have to implement in your contract a mechanism to refund Rockside for the gas fees.
An example of refund can be found in Gnosis Safe contract, method handlePayment or in our Forwarder contract, method Forward.
