Webhook-Triggered WhatsApp Replies
Your other tools can now talk to WhatsApp customers. When an external system sends a webhook, Notis automatically replies on WhatsApp--creating seamless tool handoffs without manual intervention.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Send reply
Send a reply to a specific message in a whatsapp conversation. this creates a contextual reply that shows which message you're responding to. note: the reply will be delivered to the recipient only if they have texted first.
Why this helps
Conversations across tools create coordination problems. A chatbot finds an answer but has nowhere to send it, so you copy-paste messages manually.
- Connect external tools to WhatsApp automatically
- Remove manual message copy-pasting
- Route responses without context switching
- Build sophisticated multi-tool workflows
Setup
Build it in a few focused steps.
- 1Connect WhatsApp to Notis
- 2Get your Notis webhook URL from the automation setup screen
- 3In your external tool or chatbot, configure it to POST to your Notis webhook when an event occurs
- 4Create an automation: When you receive a webhook, send a WhatsApp reply with the message payload
- 5Specify the format: Extract the message text and contact phone from the webhook and send it on WhatsApp
- 6Test by triggering the webhook from your external tool and verifying the WhatsApp message arrives
Questions about this workflow
What data format does the webhook expect?
Notis is flexible. Your webhook should include: phone_number (recipient), message_text (content), and ideally conversation_id (for threading). Notis adapts to your format.
Can I transform the webhook data before sending?
Yes. Describe the transformation in your prompt: Take the JSON from the webhook, extract the customer name, and send a personalized WhatsApp reply. Notis handles the mapping.
What if the webhook fails or sends bad data?
Notis logs the webhook attempt. Check your automation logs to see error details. Most common issue: missing phone_number field. Verify your webhook payload includes it.
Can multiple external tools use the same webhook?
Yes. One webhook can receive events from multiple sources. Specify in your prompt how to route different message types.
