Fondo webhooks events

Fondo Webhooks & Events

Overview

Fondo itself does not send webhooks. Instead, build event-driven workflows using webhooks from the same providers Fondo connects to: Stripe (revenue), Gusto (payroll), Plaid (bank transactions), and Mercury (banking).

Provider Webhooks

Provider	Key Events	Use Case
Stripe	charge.succeeded, invoice.paid	Revenue tracking, MRR alerts
Gusto	payroll.processed, employee.created	Payroll cost alerts, headcount
Plaid	transactions.sync, item.error	Expense monitoring
Mercury	transaction.created	Real-time spend tracking

Instructions

Stripe Revenue Webhook

import Stripe from 'stripe';
const stripe = new Stripe(process.env.STRIPE_API_KEY!);

app.post('/webhooks/stripe', express.raw({ type: '*/*' }), (req, res) => {
  const sig = req.headers['stripe-signature'] as string;
  const event = stripe.webhooks.constructEvent(
    req.body, sig, process.env.STRIPE_WEBHOOK_SECRET!
  );

  switch (event.type) {
    case 'charge.succeeded':
      const amount = (event.data.object as Stripe.Charge).amount / 100;
      console.log(`Revenue: $${amount}`);
      // Update internal dashboard
      break;
    case 'invoice.paid':
      // MRR tracking
      break;
  }
  res.sendStatus(200);
});

Gusto Payroll Webhook

// Gusto sends webhooks when payroll is processed
app.post('/webhooks/gusto', express.json(), async (req, res) => {
  const { event_type, data } = req.body;

  if (event_type === 'payroll.processed') {
    const totalPayroll = data.totals.gross_pay;
    console.log(`Payroll processed: $${totalPayroll}`);
    // Alert if significantly different from budget
    if (totalPayroll > monthlyPayrollBudget * 1.1) {
      await sendAlert(`Payroll exceeded budget by ${((totalPayroll / monthlyPayrollBudget - 1) * 100).toFixed(0)}%`);
    }
  }
  res.sendStatus(200);
});
