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
Sending prep materials requires finding the file, uploading it, and sharing it—multiple steps right before the meeting when you're already busy.
- Pre-staging: materials are ready to share before attendees even ask
- Zero friction: when someone asks 'Can you send the agenda?', you instantly forward it from your media library
- Organized: all meeting materials live in WhatsApp, not scattered across email and cloud storage
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and WhatsApp business accounts to Notis.
- 2Store your template prep materials in a folder (Notis can reference them or pull from Google Drive).
- 3Create a new automation: 'When a new event is created, upload the [agenda template] and [prep checklist] to my WhatsApp media library.'
- 4Set the trigger to 'Event Created'.
- 5Pick your run-report channel.
- 6Verify files appear in your WhatsApp business account's media library after scheduling a test event.
Questions about this workflow
Can I upload different materials for different meeting types?
Yes. Set up multiple automations—one for strategy sessions (uploads strategy template), another for 1-on-1s (uploads 1-on-1 template), etc.
Do I need to manually add files to my folder every time I want new materials?
You can set it up to reference a 'current' template folder, and just update files there. Notis will upload the latest version when each new event is created.
What file size limits does WhatsApp have for uploaded media?
Documents: 100 MB max. Images: 5 MB. Videos: 16 MB. Most agendas and prep docs fall well under these limits.
