FreshBooks integration for Claude and Codex

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.

Delete a webhook callback from a FreshBooks account. Use when you need to remove an existing webhook subscription that is no longer needed.

This action returns detailed information about all staff members (owners, admins, employees) in a business group, including their roles, email addresses, and active status. Use this to discover team members before assigning time entries or tasks.

List all businesses associated with the authenticated user. This action retrieves business membership information from the FreshBooks Identity endpoint, showing all businesses the user has access to along with their role in each business. The business_id from this response is required for many other FreshBooks API calls.

Retrieves all clients for a FreshBooks account. Clients are entities you send invoices to. Supports pagination, filtering by email/user ID/visibility state, sorting, and includes optional balance data (outstanding, credit, draft, overdue).
