## Verdicts

**Telegram Bot API.** Telegram's first-party bot interface is free, needs no card and documents 185 methods on one page with a dated changelog and numeric send limits. No OpenAPI document, status page, SLA or idempotency key was found, one token controls the whole bot and travels in the URL, and a person must create the bot in a chat with @BotFather.

**WhatsApp Business Platform (Cloud API).** The first-party WhatsApp API has a public OpenAPI document, Markdown docs with llms.txt, numeric rate limits and a test number that sends without a payment method. Setup needs a person in three Meta dashboards, no idempotency key was found for sends, and Meta's terms restrict general-purpose AI assistants on the platform.

## 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.

### WhatsApp Business Platform (Cloud API)

1. Check when the user last wrote. Free-form messages are accepted only within 24 hours of the user's last message. After that, send an approved template.
2. Record the message id from each send and match it to `messages` webhook statuses. Many failures arrive only by webhook, and no idempotency key was found.
3. On error 130429 or 131056 wait and retry. Meta's guidance for the per-recipient limit is 4^X seconds, with X rising by one per failure.
4. Verify `X-Hub-Signature-256` with the app secret on every webhook, and deduplicate, because failed deliveries are retried for up to 7 days.
5. Request `health_status` on the phone number before a campaign to see whether the app, business, account, number and template can send.
