Catch payment failures sooner
Put failed payment details where you can act on them, with a WhatsApp message based on the webhook payload.
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
A failed transaction can sit unnoticed while you switch between payment tools and customer conversations.
- Bring payment failures into your daily communication flow
- Include the failure reason when available in the event
- Avoid repeated dashboard checks

- 4Pick the webhook trigger and choose where run reports go.
- 5Test with one real example.
Questions about this workflow
Will the message include the failure reason?
Notis can include it when the incoming webhook provides a reason. If that detail is missing, the message can still include other available event information.
Can this start without a built-in Airwallex trigger?
Yes. Choose the Notis webhook trigger and send the relevant Airwallex webhook events to it.
