File limits

WhatsApp limits files to about 5 MB for images, 16 MB for video and audio, and 100 MB for documents. The link must be reachable without a login.

24-hour window

Free-form messages (text, media, buttons, lists) can only be sent while the contact's 24-hour conversation window is open, meaning they messaged you in the last 24 hours. Outside the window, send an approved template instead. If the window is closed you get a SESSION_EXPIRED error.
