Create Webhook
Register a new webhook callback for a FreshBooks account. Webhooks notify your application when specified events occur (e.g., when invoices are created, clients are updated, or payments are received). **Prerequisites:** Obtain a valid account_id using the List Businesses action first. **Important Notes:** - FreshBooks implements a verification mechanism to ensure you own the callback URI. The 'verified' field will initially be false. - Your webhook endpoint must respond with a 2xx HTTP status code. Any other status code (including 3xx redirects) is treated as a failure. - Webhook requests have a 10-second timeout. - Requires 'user:webhooks:write' OAuth scope. **Common Event Types:** client.create, client.update, client.delete, invoice.create, invoice.update, invoice.delete, payment.create, payment.update, payment.delete, expense.create, expense.update, expense.delete.
