# Catch invoice fraud: new IBAN for a known supplier

**Use case:** 

An AI payment agent or accounts-payable bot receives an invoice saying the supplier's bank details have changed. This task checks the payment before money moves: IBAN checksum, a known payee suddenly asking for a new IBAN, and bank-change or pressure wording in the message. You get ALLOW, REVIEW or BLOCK with the reasons. Swap in your own payment and supplier history.

## Input

```json
{
  "iban": "NL91ABNA0417164300",
  "payee_name": "Jansen Bouw B.V.",
  "amount": "4850.00",
  "message_text": "Dear customer, please note our bank details have changed. Pay invoice 2026-118 (EUR 4,850.00) today to our new account NL91 ABNA 0417 1643 00, urgent, otherwise delivery stops.",
  "known_payees": [
    {
      "iban": "NL02RABO0123456789",
      "name": "Jansen Bouw BV"
    }
  ],
  "attest": false
}
```

## Output

```json
{
  "index": {
    "label": "#",
    "format": "integer"
  },
  "verdict": {
    "label": "Verdict",
    "format": "string"

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/lerider/payee-check.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
