3All registered vendors are fetched from the Vendors sheet in Google Sheets
4The sender's phone is matched against the registry to determine if they are registered
5Registered vendors have their submission logged to the Submissions sheet with a unique reference ID
6An immediate WhatsApp confirmation is sent back to the vendor via Twilio
7Unregistered senders are logged as rejected attempts and receive a not-registered reply

FAQ

About this template

How long does it take to set up WhatsApp Vendor Ingest & Authenticator?

Most people finish in minutes following the guide. If you’ve never used n8n before, budget an hour — the first workflow is always the slowest.

What if I get stuck?

Email support@n8ntemplatestore.com. Free basic support is included with every purchase, and you’ll get a reply from our team within 24 hours. If setup needs more than email, we can schedule a call.

Do I need to pay for Twilio?

API costs are separate and go directly to the provider — typically a few dollars a month at most for a solo business. Full breakdown is in the setup guide.

Can I customize the workflow?

Yes, completely. You own the .json — edit nodes, swap in your own prompts, re-wire the logic. Our support team can help you plan customizations over email.

What if it doesn’t work for me?

Refunds are issued only as described in our Refund Policy (https://n8ntemplatestore.com/refund-policy). Or add Setup Service at checkout for a live install and test session — pick any tier you prefer.
