Thanks for the advice! For some platforms like Telegram, I already have payments implemented, as it’s supported out of the box. But for WhatsApp and Instagram, I’m looking into a custom payment integration (maybe sripe/paypal)

Exactly, that’s what I’m trying to achieve

Thanks! Each channel connects via webhooks into a unified messaging layer, so the inbox and flow engine are completely channel-agnostic. Rate limits are handled with a Redis-based spam guard that tracks outbound volume per chat and escalates to org-level blocks if things go sideways, keeps both us and the platforms happy.
