I need to extract some messages from a specific discord channel for automated cryptotrading.

I already have experience with Telegram, where I created a parsing bot that with via webhook it sends a json to my broker.

I understand that it is possible to do this with Discord's webhook, but this option is available only if the server has been created by me. There are also valuable options like integromat, but I cannot push+ capture webhooks from a public channel, I only have the channel Id info...

So what I'm asking is... is it possible to capture/parse messages from Discord public servers?
