What this skill does
Fondo Webhooks & Events Prerequisites A signing secret in the secret manager, raw-body validation, event ledger, approved destinations, redaction policy, and synthetic fixtures. Output Return opaque event ID, signature result, idempotency outcome, destination status, and redacted error category. Keep financial payloads and credentials out of logs. Error Handling Reject invalid signatures, quarantine unknown schemas or destinations, bound retries, and pause downstream processing on access or reconciliation failures. Examples Deliver a fictional signed event twice and confirm only the first is processed; reject an invalid signature without logging its payload or forwarding data. 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 Gusto Payroll Webhook Resources Stripe Webhooks Gusto Webhooks Plaid Webhooks Next Steps For performance optimization, see fondo-performance-tuning.
