Your own business number
The message comes from your number with your business name on top, over the official WhatsApp Business Platform.
n8n
Send WhatsApp messages from n8n
n8n has its own WhatsApp node, but it needs a Meta developer account, a Meta app and an access token. If your number already runs on Tobachat, one HTTP Request node does the job.
Setup
The HTTP Request node in 4 steps
1
Method and URL
Pick POST and enter https://api.tobachat.nl/v1/send-template.
2
Key
Under Authentication pick Generic Credential Type, then Header Auth, with X-API-Key as the name and your key as the value.
3
Body
Turn on Send Body, pick JSON and Using JSON, and set the field to Expression, so n8n fills in values from the previous step.
4
No duplicates
Under Send Headers, set Idempotency-Key to {{ $execution.id }}-{{ $itemIndex }}. A retry from n8n then won't go out twice.

}Two ways
The WhatsApp node or an HTTP Request
| n8n's WhatsApp node | HTTP Request to Tobachat | |
|---|---|---|
| What you need | A Meta developer account, a Meta app and an access token | An API key from Tobachat |
| Opt-outs | You track them yourself | A number that sent STOP gets nothing more |
| Replies | In n8n, with the WhatsApp Trigger | Alert and reply in your shared inbox |
Examples
Workflows that send an alert
A site that goes down
A Schedule Trigger checks your site every few minutes. When it doesn't answer, whoever is on call gets a message.
A monitoring tool
If your uptime or server monitoring sends a webhook, n8n turns it into a WhatsApp alert.
Failing payments
When your store or payment provider reports a run of failed payments, your team hears about it at once.
A stock feed gone quiet
No new feed for a few hours, and n8n sends an alert.
With Tobachat
Alerts and replies in one place
Only to people who asked
Alerts go to people who signed up. A number that opted out gets nothing, even if n8n tries.
Every alert in your inbox
You see every alert in your shared inbox, and your team picks up any reply right there.
More than alerts
The same number answers customer questions too, handled by your team or the AI agent.
Pricing
What it costs
Alerts are part of every plan. Start free, then €29, €99 or €199 a month, cancel any month. Meta charges per message on top, depending on the recipient's country.
