Route French KYB onboarding checks with Sirenic, Slack, and Google Sheets

Quick overview

Your signup form posts a SIREN, and one Sirenic call returns the official KYB file of the French company, with sanctions screening of every officer. Readable rules approve, review or stop the client.

How it works

1. The SIREN is checked first: not nine digits, the form gets a 400 and nothing is billed.
2. One call to /v1/kyb/{siren} ($0.15). Errors are never billed, and Slack says why.
3. A Code node stops a ceased company; insolvency notices, sanctions matches to verify and any block missing or not fully read go to a human; only a complete, clean file is approved.
4. Slack alerts compliance; the sheet logs each decision, reasons and a dated source line.

Setup

1. Create an API key at https://api.sirenic.eu/compte?utm_source=n8n&utm_campaign=18271.
2. Add a Header Auth credential (X-Api-Key, your srn_live_ key) on Get the KYB file.
3. Pick your Slack channel on the three Slack nodes.
4. Create a sheet with the headers Checked at, SIREN, Company, Decision, Reasons, Screening, Completeness, Missing blocks, Sirenic: source, then select it on the log node.
5. Test with the SIREN 418009726.
