approveTransactionSend.js

//
// approve a transaction given a pending approval ID
//
// This example shows how to approve a pending approval created when another user attempted
// to send a transaction but had a policy trigger, preventing it from going through. In order to
// complete the transaction another admin on the wallet must approve the pending approval for
// the transaction send.
