Webhook-Triggered Media Uploads
Media should flow automatically between your tools and WhatsApp. When an external system sends a webhook with media, Notis uploads it to WhatsApp servers instantly--ready for messaging campaigns.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Upload media
Upload media files (images, videos, audio, documents, stickers) to whatsapp servers. the uploaded media gets a media id that can be used in send media or other messaging actions. supported formats: - images: jpeg, png (max 5mb) - videos: mp4, 3gpp (max 16mb) - audio: aac, m4a, amr, mp3, ogg (max 16mb) - documents: pdf, doc, docx, ppt, pptx, xls, xlsx (max 100mb) - stickers: webp (max 500kb, 512x512 pixels)
Why this helps
You generate media in one tool, download it, manually upload to WhatsApp, then reference the media ID. This breaks automation and creates bottlenecks.
- Automate media uploads from external sources
- Eliminate manual file handling
- Build media IDs for downstream messaging
- Integrate media generation tools directly with WhatsApp
Setup
Build it in a few focused steps.
- 1Connect WhatsApp to Notis
- 2Get your Notis webhook URL
- 3Configure your external tool to POST the webhook with a media URL or file reference when media is ready
- 4Create an automation: When you receive a webhook with a media file or URL, upload it to WhatsApp servers
- 5Specify file type expectations: The webhook will contain a URL to an image file. Download and upload it to WhatsApp.
- 6Test by sending a webhook with a valid media URL and check WhatsApp servers for the uploaded file
