Good day.
If you need to parse phone numbers of subscribers from channels, I will say it directly. This is technically impossible. Viber hides the lists of participants and their contacts in channels and communities from everyone except administrators. It will not be possible to bypass this restriction without administrator access.
If the goal is to collect textual content, photos, and messages published in these 49 channels, this can be implemented. I will write a Python script that automates the collection of message history and exports all data into a convenient Excel or CSV table.
What exactly is the task at hand for you, an attempt to obtain a contact database for mailing or collecting content from the publications in the channels?
