If you have a media file you would like to send that is not accessible via a public URL, you can upload it to 2Chat and get a public URL for it there.
To do that, upload it to your 2Chat files at app.2chat.io/files, then get its public URL by clicking on the button highlighted in the image below.
Tip: If you are using a Google Drive public URL, download the file and reupload it to 2Chat to guarantee it is publicly accessible by our API.
