Learn how bots work
Tokens, updates, webhooks versus polling, and the shape of a reply.
Pick a platform
Telegram is the fastest to start; Discord and Slack fit communities and teams; WhatsApp needs a business account.
Build the first version
Handle one command, validate input and test the messages before you send them.
Host it
Webhook bots run well on serverless; gateway bots need a long-running process.
Secure it
Keep tokens out of code, verify webhook signatures and ask for the fewest permissions.
Scale and keep it running
Respect rate limits, retry with backoff, add a queue and watch your error rate.
