Altoviz Developer Hub
Welcome to the Altoviz Developer Hub — your home for building on top of Altoviz.
Whether you’re a developer wiring Altoviz into your own application or a power user looking to automate the busywork, you’re in the right place. Everything you need to integrate, script, and automate invoicing and accounting with Altoviz lives here: clear documentation, ready-to-use examples, and a set of tools designed to fit the way you already work.
Every action available in the Altoviz web app is also available to you programmatically — and it’s 100% free for developers, most of the time free for your users too.
Choose your tool
Section titled “Choose your tool”There’s no single right way to work with Altoviz. Pick the tool that matches your project and skill set — they all talk to the same platform, so you can mix and match freely.
| Tool | Best for |
|---|---|
| REST API | Integrating invoicing and accounting directly into your own application or backend |
| CLI | Managing your account from the terminal, scripting tasks, and powering shell automations |
| MCP server | Connecting an AI assistant like Claude or ChatGPT to your Altoviz account in plain language |
| Automation | Building no-code workflows with tools like Make, n8n, and Zapier |
REST API
Section titled “REST API”A RESTful HTTP API with predictable resource URLs, JSON payloads, API-key authentication, webhooks, pagination, and generous rate limits. The foundation everything else is built on. → Get started
altoviz is a single self-contained binary for macOS, Linux, and Windows — no runtime required. Manage customers, invoices, quotes, products, and more straight from the terminal, with multiple output formats and shell completions. → Install the CLI
MCP server
Section titled “MCP server”Connect ChatGPT, Claude, or any Model Context Protocol client to Altoviz and just ask, in plain language, for what you need — “Create a draft invoice for Acme Corp” or “List this customer’s unpaid invoices.” → Connect your assistant
Automation
Section titled “Automation”Save time and cut out manual data entry by connecting Altoviz to the apps you already use. Build no-code workflows with Make, n8n, and Zapier. → Explore automations
