Webhooks Trigger Instant Media Delivery
Your invoice generator sends a webhook saying the invoice is ready. Notis automatically delivers the PDF to your client's WhatsApp. Fast, direct, no email delays.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Send media
Send a media message to a whatsapp number. note: the media will be delivered to the recipient only if they have texted first.
Why this helps
Neurodivergent founders manually download files from one tool, switch to WhatsApp, and send them manually. This multi-step process is cognitively expensive and error-prone. Files get forgotten, wrong versions are sent, and clients wait.
- One-step file delivery from any tool to WhatsApp
- No manual downloads or app-switching
- Faster client communication
- Reduces errors from sending wrong versions
- Centralizes file distribution in WhatsApp audit trail
Setup
Build it in a few focused steps.
- 1Connect your Airtable and WhatsApp accounts to Notis.
- 2Create a new automation called 'Webhook Media Delivery' and set the trigger to 'Webhook'.
- 3Write your prompt: 'When a webhook is received with a media file, send that media to the specified WhatsApp number. Include a brief message about what the file is.'
- 4Notis provides a webhook URL. Configure your file-generation tool (invoice app, report tool, etc.) to post to this URL when files are ready.
- 5Test by triggering a file generation event and verifying it arrives on WhatsApp as a media message.
Questions about this workflow
Which file types can I send?
Images (JPG, PNG), videos (MP4), audio (MP3, M4A), and documents (PDF, Word, Excel). Maximum file sizes are enforced by WhatsApp (5MB for images, 16MB for video/audio, 100MB for documents).
Can I send multiple files in one webhook?
Yes. Include multiple files in the webhook payload and Notis will deliver them as separate messages or in a media collection if WhatsApp supports it.
Do I need to manually upload files to WhatsApp first?
No. Notis handles the upload and delivery in one step when the webhook triggers.
Can the client reply or is it one-way?
WhatsApp allows replies, so clients can acknowledge receipt, ask questions, or provide feedback right in the same conversation.
