you need to block requests from being routed to your PHP interpreter

However, you pay 2.7% for that convenience

I built this for fun and my own notifications. I don't think there's much commercial value here since there's zero moat. But it would be nice if we could raise funds for Signal.

The bot has access to any sent messages to yourself, plus any chatter in group chats if you have enabled that. So don't use it for sensitive stuff, and use a dedicated group. It was developed to relay sensor data and such, not war plans.

Contact me via the support link?

The URL that botmaster gave you is a page that lists your API endpoints (multiple if you have invited the bot to any group chats)

Messaging is internally rate limited and capped per recipient. And it uses a sender pool.
