You are unable to put this URL link in a "Send Message - File" because the link from Viber is not a direct file link. Alternatively, to send the file back to your user, you can use "Send Message - Text" to print the link, the user can tap the link to download the file. **3- Send Message** * For Each: JSON should be under 2000 characters. * Ecommerce: The JSON should be under 2000 characters so you might be unable to list 10 products per page according to your products information length (try 5 or 6 per page). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
