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

• WhatsApp (AI agent) — 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?", "log this receipt" and you send the photo). An agent powered by Claude interprets the message and acts on your real data.
• Claude, Cursor and ChatGPT (via MCP) — 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.
• Bank via PSD2 (through Powens) — bank account read-only: each deposit matches its invoice and marks it paid (it alerts you on WhatsApp), each charge becomes an expense suggestion with its IVA.
• REST API — for custom integrations with x-api-key or JWT: your code creates invoices, logs expenses, emits Verifactu or generates the Modelo 303. Spec at /openapi.json, Swagger at /api-docs/, examples at https://github.com/Santy1422/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.

The Stripe nuance

There's no native Stripe gateway integration (yet). What does work: payouts settled by Stripe, card or transfer land in your bank account, and FacturaHub reconciles them from the bank (PSD2, via Powens) like any other deposit, matching them to their invoice. 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).

WhatsApp — AI agent

You talk to your invoicing on WhatsApp: "invoice 1,000 to Acme", "who owes me?", or send a receipt photo. An agent powered by Claude 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.

PSD2 bank (via Powens)

Bank account read-only: each payment matches its invoice, each charge becomes an expense suggestion. Stripe payouts land in your bank and reconcile the same way.

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: WhatsApp (AI agent), Claude/Cursor/ChatGPT via MCP server, WooCommerce (orders to invoice), your bank via PSD2 through Powens (reconciliation), the REST API with OpenAPI 3.1 spec and Verifactu (AEAT) included. Everything shares a single backend.

Does FacturaHub integrate with Stripe?

Not with a native gateway integration (yet). What does work: payouts settled by Stripe land in your bank account and FacturaHub reconciles them from the bank (PSD2, via Powens) like any other deposit, matching them to the corresponding invoice.

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 (WhatsApp, MCP, WooCommerce, PSD2 bank, API, Verifactu) are in the single free, unlimited plan. Only AI is metered: 25 free actions per month and one-off token packs from €4.99 if you need more. No tiered plans or 7-day trial.
