n8n-nodes-fints

This is an n8n community node that integrates with the Financial Transaction Services (FinTS) interface used by German banks, allowing you to retrieve real-time account balances within your n8n workflows.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation, or install directly via npm:

npm install n8n-nodes-fints

Operations

• Get Account Balance: Retrieves the current balance and currency information for a specified bank account.

Credentials

To authenticate with your bank's FinTS server, you need:

• User ID / Login: Your customer identification number.
• PIN: Your Personal Identification Number.

The Bank Code (BLZ) and FinTS server URL are set via the node parameters or by choosing your bank during credential setup. The available banks are defined in nodes/FintsNode/banks.json. To support additional institutions, add an entry with value, displayName, blz, and fintsUrl to this file and rebuild the project.

Once you have these details, create new credentials in n8n under Settings → API Credentials, select FinTS, and enter the above information.

Compatibility

• Tested with n8n versions >= 0.150.0.
• Compatible with FinTS versions 1.1, 2.2, and 3.0.

Usage

1. Add the FinTS node to your workflow.
2. Select the FinTS credentials you created.
3. Choose the operation: Get Account Balance.
4. Configure the parameters. The node automatically retrieves all accounts linked to your login.
5. Optionally, set Start Date and End Date to limit the booking range. If left empty, the node fetches statements from the last 14 days up to today.
6. Execute the workflow to receive a response object containing balance,currency, bank, account, and an array of transactions.

Automated releases

Publishing from CI requires an npm automation token stored as the NPM_TOKEN repository secret. Generate the token in the npm account settings, ensure it has automation scope, and add it under Settings → Secrets and variables → Actions before pushing release commits or tags. The GitHub Actions workflow validates that the secret is present and aborts with a descriptive error if it is missing.
