finAPI Advisory: Beware of Fraudulent Payment Requests

In recent days, there has been an increase in phishing emails containing fake tax notifications – allegedly sent on behalf of the German Federal Central Tax Office (BZSt). These messages urge recipients to settle an “outstanding tax payment”. The included link leads to a fake website featuring a deceptively authentic-looking finAPI payment form.

The scammers’ exact goals vary depending on the case – either it’s classic phishing (stealing online banking credentials) or scamming, where payments are redirected directly to fraudsters’ accounts.

To help you avoid falling victim to such fraud attempts, we explain what to look out for and how to identify suspicious pages.

What is the finAPI Webform?

The finAPI Webform is a secure online form that allows users to:

The Webform is used by partner companies, for example, in finance apps, accounting or tax software, and online shops for payment processing. It can be integrated either directly by finAPI (under finapi.io) or by a finAPI customer on their own website.

In the current scam, third parties are trying to mimic the design and trusted appearance of our Webform in order to deceive users.

How to spot a fake Webform

Here are some simple but effective checks to help you distinguish real from fake pages:

1. Check the URL

Look closely – fraudsters often use deceptively similar domains.

2. Inspect sender and language

Scammers are increasingly using AI-based tools to improve their attacks – yet these clues still offer valuable indicators of suspicious content.

3. Question the plausibility

4. Open links independently

Do not click directly on links in emails when sensitive data or payments are involved.

If a message involves personal or security-sensitive information, always access the website directly –never through a provided link.

Example: You receive a login request for an online portal. Instead of clicking the link in the email, open your browser and type the portal’s official address manually—or find it via a search engine. This ensures you’re on the real site.
