Before you call either

Telegram Bot API

  1. Send POST https://api.telegram.org/bot<token>/sendMessage with chat_id and text. Keep the token out of logs, because it is part of the URL.
  2. On HTTP 429 wait the parameters.retry_after seconds before retrying. Stay under one message a second per chat and 20 a minute per group.
  3. Call getUpdates with offset set to the last update_id plus one, or the same updates return. Updates are kept for at most 24 hours.
  4. A retried send can post twice, as there is no idempotency key. Record the returned message_id before retrying after a timeout.
  5. In groups the bot sees only commands and replies unless privacy mode is disabled in @BotFather or the bot is an admin.

Twilio API + MCP

  1. Use the hosted docs MCP to find the endpoint, then call the REST API with a restricted API key
  2. Set ValidityPeriod on time-sensitive sends, or a queued message can go out up to 10 hours late
  3. Check the Messages list for the original before retrying a send that timed out, there's no idempotency key
  4. On a trial account, send only to verified numbers in the sign-up country using Twilio's message templates, custom bodies aren't available until you upgrade
  5. Validate X-Twilio-Signature on every inbound webhook
