What problem does it solve?

This Skill eliminates the need to manually assemble and validate FastBill invoice operations, letting you reliably query and update invoices, customers, payments, reminders, and e-invoice exports using structured inputs.

Core Features & Use Cases

  • XML API bridging with validation: Converts JSON-shaped request data into FastBill’s required XML payloads and parses XML responses back into usable structured output.
  • Gateway-safe request patterns: Uses the built-in http_request flow for live calls so Basic auth is injected by the HybridClaw gateway via the FASTBILL_BASIC_AUTH secret route.
  • Read vs write guardrails: Enforces operator-grant for mutating services (e.g., invoice.create, invoice.setpaid, invoice.sendbyemail) and supports dry-run for safer conversions from messy inputs.

Quick Start

Ask the AI to create an invoice draft from tracked time for customer 123 by calling invoice.create with operator-grant enabled.
