What FacturaHub connects with. What really works today.

This page is an honest hub: what FacturaHub really connects, today, and what it doesn't. Instead of a logo wall of integrations that don't exist, we tell you the ones in production and the ones on the roadmap. FacturaHub has a single backend shared by all channels, so any data that comes in through one integration appears instantly in the others.

What it connects today

• Claude, Cursor and ChatGPT (via MCP) — the integration that defines FacturaHub: you talk to your invoicing like with a person ("invoice 1,000 to Acme with 21% IVA", "who owes me?") and the agent acts on your real data. MCP server at /mcp with real tools (create_invoice, get_overdue, get_profit_loss, get_tax_summary, get_deductible_expenses, receipt OCR, get/save_business_context). Auth via OAuth 2.0 or x-api-key. Step by step at /es/spain/mcp-facturacion.
• WooCommerce (orders to invoice) — connect your store and each order becomes an invoice with sequential numbering and correct tax data. The only e-commerce integration today.
• n8n (no-code automation) — connect n8n to the API with HTTP Request nodes and build whatever flow you want without coding: an order comes in, an invoice goes out and sends itself. Step by step and a ready-to-import workflow at /es/spain/n8n.
• REST API — for custom integrations with x-api-key or JWT: your code creates invoices, logs expenses, emits Verifactu or prepares the quarterly IVA summary. Spec at /openapi.json, Swagger at /api-docs/, examples at https://github.com/FacturaHub-com/facturahub-api. Detail at /es/spain/api.
• OpenAPI→MCP bridge — the same spec doubles as a bridge: point any bridge at /openapi.json and auto-generate tools for your agent.
• Verifactu (AEAT) — you don't connect it, it comes included and free: when you emit an e-invoice, FacturaHub signs the record and sends it to the Tax Agency, returning the fiscal id and QR. Mandatory in January 2027 (companies) and July 2027 (freelancers), already operational so you can use it earlier. If you want to emit it from your own code, there's an open guide with examples at https://github.com/FacturaHub-com/facturahub-verifactu.

The Stripe nuance

There's no Stripe gateway integration or bank connection: you mark payments yourself (or ask the AI from Claude or the dashboard). We'd rather be clear before you assume it.

Coming soon

What isn't there yet (and we don't announce as available):

• Native Zapier or Make integration.
• Outbound webhooks — events like invoice.paid calling your URL.
• Public testing sandbox.
• Versioned base path /v1 — today the API lives under /api.
• E-commerce connectors beyond WooCommerce.

Until they arrive, the REST API and MCP cover practically any flow. Everything free and unlimited; only AI is metered (25 actions/month, one-off packs from €4.99).

Claude (MCP) — AI agent

You talk to your invoicing with the AI: "invoice 1,000 to Acme", "who owes me?". Connect Claude via MCP and the agent acts on your real data.

Claude / Cursor / ChatGPT (MCP)

MCP server at /mcp with real tools (create_invoice, get_overdue, get_profit_loss, get_tax_summary, OCR). OAuth 2.0 or x-api-key auth. See /es/spain/mcp-facturacion.

WooCommerce — orders to invoice

Connect your store and each order becomes an invoice with sequential numbering and tax data. The only e-commerce integration today; more connectors on the roadmap.

REST API — x-api-key or JWT

Custom integrations from your code: invoices, expenses, Verifactu, Modelo 303. OpenAPI 3.1 spec at /openapi.json, Swagger at /api-docs. Detail at /es/spain/api.

OpenAPI 3.1 → MCP bridge

Point any OpenAPI-to-MCP bridge at /openapi.json and auto-generate tools for the full API for your agent, without writing integration code.

Verifactu (AEAT) included

You don't connect it: it comes included and free. When you emit an e-invoice, FacturaHub signs and sends the record to the AEAT. Mandatory in 2027.

Coming soon (honest)

Native Zapier/Make, outbound webhooks, public sandbox, /v1 base path and e-commerce connectors beyond WooCommerce are on the roadmap. Not there yet.

Frequently asked questions

What does FacturaHub integrate with today?

In production: Claude/Cursor/ChatGPT via MCP server (AI agent), WooCommerce (orders to invoice), n8n via the API, the REST API with OpenAPI 3.1 spec and Verifactu (AEAT) included. Everything shares a single backend.

Does FacturaHub integrate with Stripe?

Not yet. There is no payment gateway or bank connection: when you get paid, you mark the invoice as paid yourself or ask the AI.

How do I connect my online store?

Today with WooCommerce: connect the store and each order becomes an invoice with sequential numbering. Connectors with other e-commerce platforms are on the roadmap. For any other store or your own system, you can create the invoice from your code with the REST API.

Is there a Zapier or Make integration?

Not yet, and we prefer to be honest: native Zapier/Make integration and outbound webhooks are on the roadmap as coming soon. In the meantime, the REST API (x-api-key or JWT) and the MCP server let you build practically any flow with your own tools.

How do I connect my AI agent?

Through the MCP server at /mcp. You connect Claude Desktop, Claude Code, Cursor or ChatGPT with OAuth 2.0 or your x-api-key and your agent gains real tools on your account. The step-by-step, with example config, is at /es/spain/mcp-facturacion.

Do the integrations have a cost?

No. All integrations (MCP, WooCommerce, API, Verifactu) are in the single free, unlimited plan. Only AI is metered: 10 free actions per month and one-off token packs from €4.99 if you need more. No tiered plans or 7-day trial.
