I send a message to a channel using this method
Destination URL
https://chatapi.viber.com/pa/post
Post data
{ "auth_token":"your_auth_token", "from":"your_user_id", "type":"picture", "text":"Picture description", "media":"https://www.images.com/img.jpg" }
This code works. Everything is fine.
Should I always keep access to the image https://www.images.com/img.jpg?
I expect that after posting a message to a channel I can delete the image.
