If you have replaced your web3 provider with Fortmatic provider, nothing needs to be changed for web3 send Ether transactions to continue working.
The Fortmatic X modal will pop open and ask users to confirm their transaction once this web3 function is called on the client-side.
// Initialize providerimport Fortmatic from 'fortmatic';import Web3 from 'web3';​const fm = new Fortmatic('YOUR_API_KEY');window.web3 = new Web3(fm.getProvider());​const toAddress = '0xb159752065EA68Ef0B22249Df25864E624fec45D';const sendValue = web3.toWei(1, 'ether'); // Convert 1 ether to wei// Get user account wallet address firstweb3.eth.getAccounts((error, accounts) => {if (error) throw error;// Construct Ether transaction paramsconst txnParams = {from: accounts[0],to: toAddress,value: sendValue}// Send Ether transaction with web3web3.eth.sendTransaction(txnParams, (error, txnHash) => {if (error) throw error;console.log(txnHash);});});

Fortmatic provides the option to offer a customized gas price. If provided, it will be shown as a suggested option in the delivery fee section. One parameter addition to include a customized gas price should suffice. Gas limit is optional, if not provided, Fortmatic will smartly estimate the gas limit for the transaction!
const txnParams = {from: accounts[0],to: toAddress,value: sendValue,gasPrice: '0x2540be400', // Include your own gas price here.}
