Verified against the CapitalFlow Public API v1.0.0.

An n8n community node for CapitalFlow — manage customers and households, cashflow entries (income, expenditure, assets, hedges), detailed financial contracts, and generate shareable data-collection forms.

What it does

The CapitalFlow node covers every operation exposed by the CapitalFlow Public API:

| Resource | Operations | |---|---| | Customer | Search, get, create, update | | Cashflow Income | Create, batch create, list, get, update, delete | | Cashflow Expenditure | Create, batch create, list, get, update, delete | | Cashflow Asset | Create, batch create, list, get, update, delete | | Cashflow Hedge | Create, batch create, list, get, update, delete | | Contract | Create, list, get, update, delete — across all 26 asset/hedge contract-detail combinations (accounts, pensions, property, and insurance) | | Form | Share customer data form, share cashflow analysis form | | Household | Get the household (with members) a customer belongs to | | Organization | List members of your organization |

Households

Customers now belong to a household. When creating a customer you can either leave Household ID empty (a new household is created automatically for a main_customer) or provide an existing household's ID to add a partner or child to it. The Household resource looks up the household record for a given customer.

Contract types

The Contract resource covers all contract-detail types the API supports, split into a Category — asset (checking/savings/call-money accounts, investment accounts, building savings contracts, property, private pension, Rürup, Riester, employer pension schemes, other) or hedge (15 insurance types, e.g. liability, car, household contents, term life, income protection, private/nursing-care health insurance, other) — and a Contract Type within that category. The category disambiguates types whose names overlap between the two families (e.g. "Other"). The node exposes exactly the fields relevant to the selected category/type combination — no need to hand-craft JSON payloads for each schema.

Setup

Requirements

• n8n 1.0.0+
• A CapitalFlow account with API access enabled

Install

In n8n: Settings → Community Nodes → Install, then enter:

@luzconsulting/n8n-nodes-capitalflow

Restart n8n afterwards — the node appears as "CapitalFlow".

Credentials

The node authenticates with an API key sent as a cf-api-key header against https://api.capital-flow.de. Generate a key in the CapitalFlow dashboard under Settings → API Keys, then add it as a new CapitalFlow API credential in n8n. See CREDENTIALS.md for step-by-step setup.

Note: the API is rate-limited to 200 requests per minute per API key.
