Connect Any Tool to WhatsApp via Custom Webhooks
Send a webhook to Notis, and it delivers a WhatsApp message instantly. No need for Stripe events—connect anything to your customer chat.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Send message
Send a text message to a whatsapp number. note: the message will reflect on the recipient's phone number only if they have texted first.
Why this helps
You have events from other tools (Zapier, Make, your own backend) but they're siloed. Notifications never reach customers because there's no easy way to bridge them to WhatsApp.
- Connect any tool without custom code—just post a webhook URL
- Notifications reach customers immediately where they already chat
- You're not limited to Stripe events—anything can trigger a message
Setup
Build it in a few focused steps.
- 1Connect WhatsApp to Notis and get your unique webhook endpoint.
- 2In Notis, create a custom webhook trigger and tell Notis: 'When I send a webhook with [specific data], send a WhatsApp message saying [your custom message].'
- 3Notis provides a webhook URL. Copy it into your external tool (e.g., Zapier, Make, your backend, etc.).
- 4Test by triggering the webhook manually (Notis provides a curl example).
- 5Confirm the WhatsApp message arrives with the data you sent.
Questions about this workflow
Can I send data to Notis and have it appear in the WhatsApp message?
Yes. Use placeholders like {{name}}, {{order_id}}, {{amount}}. Notis inserts the data you send in the webhook.
How fast are webhook-triggered messages?
Nearly instant—typically delivered within 1–2 seconds of the webhook arriving. Perfect for urgent alerts.
Is the webhook URL secret/secure?
Yes. Notis provides a unique, long URL that acts like an API key. Don't share it publicly; treat it like a password.
