12. Channels: WhatsApp and Telegram with your own credentials

- WhatsApp Business API: you connect your own Meta account (phone number ID, WABA ID and token). Your templates are synchronised daily from Meta with their real category, which is the one Meta bills.
- Telegram: you connect your bot (BotFather token). The condition for this
channel is set by Telegram: the contact must have started a conversation
with your bot at least once; from then on, delivery is immediate and
reliable. The bot captures the
chat_idautomatically when the user writes to it.
