​
Overview

Method responsible for sending videos to your chats. You can work with videos in 2 ways:
  • By Link: if you have the video hosted somewhere on the internet, just send the link;
  • By Base64: if you want to send the video in Base64 format.
For more predictable API behavior, we recommend using videos encoded with the H.264 codec, which is the format supported by WhatsApp. Videos using other codecs go through an internal conversion process to H.264, which may cause intermittent sending issues or increase the final file size, potentially exceeding WhatsApp’s allowed limit.The file size must not exceed 100MB.
