n8n: scheduled company credit score monitoring workflow

[francescobianco]

Idea

Build an n8n workflow that runs daily, fetches the credit score of a watchlist of companies from Openapi, and sends a Slack alert if any score drops below a threshold.

Pseudocode for the PHP side

use Openapi\Client;

$client = new Client($token);
$watchlist = ['IT01234567890', 'IT09876543210'];

foreach ($watchlist as $vatNumber) {
    $score = json_decode(
        $client->get('https://risk.openapi.com/IT-creditscore', ['cf' => $vatNumber]),
        true
    );

    if ($score['value'] < 40) {
        // trigger Slack webhook from n8n
        yield ['cf' => $vatNumber, 'score' => $score['value'], 'alert' => true];
    }
}

n8n workflow sketch

Cron (daily 8am) → HTTP Request (PHP proxy) → IF score < 40 → Slack message

Open questions

• Is there a way to subscribe to score changes via webhook instead of polling?
• What is the recommended polling interval to avoid burning API credits?
• Would an official n8n workflow template JSON be something the project could ship in examples/n8n/?
