Automate podcast posts to Telegram: set up an RSS-to-Telegram bot to post episodes, timestamps, and show notes automatically.

Hook: Stop manually announcing episodes — automate your podcast distribution to Telegram

If you're producing regular podcast episodes, manually posting each release to Telegram channels and groups steals time and creates inconsistent reach. Creators and publishers in 2026 need repeatable workflows that post full episodes, inject timestamps and show notes, and schedule follow-ups — all automatically. This guide shows a technical, production-ready approach to build an RSS-to-Telegram bot that reliably posts new episodes, uploads or links audio, and formats timestamps and show notes for channels and groups.

Why this matters in 2026

Audio distribution has shifted: late 2025 saw renewed interest in decentralized discovery and feed-based distribution. Messaging platforms like Telegram have become primary distribution endpoints for communities, not just social sidebar platforms. That makes having a robust, automated pipeline from your podcast RSS feed to Telegram crucial for reach, retention, and monetization. Bots are now expected to do more than post links — they must preserve chapter timestamps, attach clean show notes, and optionally upload audio to Telegram to improve in-chat playback and analytics.

Overview: What you'll build

By the end of this guide you'll have a lightweight service that:

Subscribes to a podcast RSS/Atom feed and detects new episodes
Parses episode metadata (title, description, duration, GUID, enclosure URL)
Extracts chapter timestamps from feed entries or show notes
Uploads or links audio to Telegram and posts a formatted announcement to a channel or group
Handles duplicate detection, retries, rate limits, and optional scheduling

Prerequisites

Telegram Bot token (create with BotFather)
A target Telegram channel or group — add the bot as an admin (for channels, grant 'post messages')
Server or serverless environment (Heroku, Vercel, Digital Ocean, AWS, or a VPS)
Basic dev tooling: Node.js or Python runtime, ffmpeg (optional for audiograms/snippets)
Access to the podcast RSS feed (public or authenticated)

Step 1 — Register the bot and get chat_id

Use BotFather to create a bot and get a token (KEEP IT SECRET). To post to a channel, add the bot as an admin. For channels, you can use the {@code @channelusername} as the chat_id, or get numeric chat_id by sending a message and fetching updates (or using the Telegram API getUpdates during development).

Quick checklist

Create bot with BotFather and copy token
Add bot as admin to the target channel/group
Confirm the channel username or numeric chat_id

Step 2 — Choose architecture: Polling vs Webhook

Two common patterns:

Poll the RSS: cron job or scheduler fetches feeds every 5–30 minutes. Simple, reliable, and works with any hosting.
Push with webhooks: let a feed service (Inoreader, Feedbin, or a self-hosted webhook relay) notify your endpoint when a feed changes. Lower latency but requires a public HTTPS endpoint.

Recommendation: start with polling (5–10 min) for simplicity, then add webhooks for faster delivery if you need near-instant posts.

Step 3 — Parse RSS and detect new episodes

Important fields to parse:

title, guid, pubDate / published
enclosure (url, length, type)
itunes:duration / media:content / content:encoded (show notes)
chapters (Apple Podcast chapters or custom timestamp markers inside the description)

Python example: feedparser + SQLite store

import feedparser
import sqlite3

DB = 'episodes.db'
conn = sqlite3.connect(DB)
# create table if not exists
conn.execute('CREATE TABLE IF NOT EXISTS seen(guid TEXT PRIMARY KEY)')

feed = feedparser.parse('https://example.com/podcast/rss')
for entry in feed.entries:
    guid = entry.get('id') or entry.get('guid') or entry.get('link')
    if not conn.execute('SELECT 1 FROM seen WHERE guid=?', (guid,)).fetchone():
        # new episode: process entry
        process_entry(entry)
        conn.execute('INSERT INTO seen(guid) VALUES(?)', (guid,))
conn.commit()
conn.close()

Tip: persist GUIDs or enclosure URLs to avoid duplicate posts. For distributed systems use Redis or a DB with deduplication keys.

Step 4 — Extract timestamps and chapters

Podcasts often include chapter info via:

Apple Podcast chapter files (psc:chapters)
Embedded timestamp lists in show notes like "00:02 Intro"
podcast:chapters in the RSS namespace

Strategy:

Look for structured chapter tags in the feed.
If absent, parse the description with regex to extract HH:MM or MM:SS markers.
Normalize timestamps into seconds and format readable labels for Telegram.

Regex example (Python)

import re

TIMESTAMP_RE = re.compile(r'(?:(\d{1,2}:)?\d{1,2}:\d{2})')
text = entry.get('description', '')
matches = TIMESTAMP_RE.findall(text)
# convert matches to seconds and pair with following text as label

Include a short timestamp block at the top of the Telegram post, like:

Timestamps 00:00 Intro 02:15 Interview with Jane Doe 18:40 Q&A

Step 5 — Format the Telegram announcement

Formatting matters. Use Telegram's HTML or MarkdownV2 modes to make titles bold, provide clickable links, and add an inline keyboard for the full episode page or sponsorship link.

Recommended message structure

Headline: Episode number + title
Lead: One-line episode teaser
Timestamps: short list for navigation
Show notes: trimmed paragraph (use a "read more" link to full notes)
CTA keyboard: Listen on site, subscribe, or support

Example HTML payload:

<b>Episode 124 — The Future of Bots</b>
<i>We talk automation, scale, and how creators win in 2026.</i>

<b>Timestamps</b>
00:00 Intro
04:05 The bot stack
23:30 Monetization tips

<a href="https://example.com/episodes/124">Full show notes & links</a>

Step 6 — Attach audio: link vs upload

Two approaches:

Link-only: sendMessage with the enclosure URL. Telegram will render a link preview and users will be taken to the host player.
Upload (recommended for best UX): use sendAudio (or sendVoice for compressed snippets) with the episode file. Uploading enables in-chat playback, progress bar, and retains playback data for users who prefer to listen inside Telegram.

Upload considerations:

Telegram supports large files (2GB+ as of 2026) — usually enough for high-quality episodes.
To reduce bandwidth, you can upload a smaller MP3/AAC for Telegram and keep the full-quality master on your host.
Use multipart/form-data to POST the file to sendAudio endpoint, or provide the HTTP URL directly (Telegram will fetch it server-side).

Node.js snippet: sendAudio by URL

const fetch = require('node-fetch')

const token = process.env.TG_TOKEN
const chatId = '@yourchannel'
const audioUrl = entry.enclosure.url

await fetch(`https://api.telegram.org/bot${token}/sendAudio`, {
  method: 'POST',
  body: new URLSearchParams({
    chat_id: chatId,
    audio: audioUrl,
    caption: generateCaption(entry),
    parse_mode: 'HTML'
  })
})

Pro tip: If your hosting provider blocks HEAD requests or restricts cross-origin fetches, download the file to your server and upload to Telegram to ensure reliability.

Step 7 — Inline keyboard & scheduled follow-ups

Add an inline keyboard to direct listeners to your website, sponsorship links, or paid content. For timed reposts (e.g., cross-post reminders or short clip teasers), use your scheduler (cron, APScheduler, or serverless triggers) to post additional messages at peak times. If you plan to sell merch or sponsor-led offers, consider integrating a portable checkout & fulfillment path so listeners can convert without leaving the chat.

Step 8 — Rate limits, retries, and error handling

Handle errors robustly:

Respect Telegram API rate limits — implement a small queue with exponential backoff for 429 errors
Retry downloads/uploads on transient network errors
Log failures to a central store (Sentry, Datadog) and notify yourself in a private admin chat when posting fails

Step 9 — Testing and edge cases

Test with episodes that have no enclosure (skip or send link-only)
Normalize HTML in show notes to avoid Telegram parse errors; escape reserved characters if using MarkdownV2
Validate timestamps — ensure they fit episode duration and discard invalid markers
Support truncated descriptions — use a short excerpt with a link to full notes

Advanced: audiograms, clips, and user-triggered actions

To increase engagement, generate short audiograms (15–60s) from episodes using ffmpeg and an image template. Post these as animated previews or voice messages to tease the episode. You can also implement commands like /latest or /episode124 to allow group members to fetch specific episodes on demand. For producing visual assets and short social previews, pair your ffmpeg pipeline with a hybrid photo workflow so imagery and clips are cached and optimized for fast posting.

Integrations and workflow examples

Use cases and integrations popular in 2026:

CMS + RSS: When you publish on your CMS, it updates the RSS and your bot polls the feed and posts automatically.
Analytics: Push post events to analytics systems to track CTR and listening behavior (via custom short links or server-side logging when Telegram fetches your hosted audio). See an analytics playbook for ideas about edge signals and personalization strategies you can apply to post-level metrics.
Membership gating: For paid content, post teasers publicly and full audio to members-only channels where the bot posts only after verifying subscription status. Consider micro-subscription models for reliable recurring revenue.

Case study (real-world pattern)

Publisher X (a 2025 news podcast) moved from manual posting to an automated pipeline. They: parsed chapters to produce timestamped Telegram posts, uploaded a 128kbps copy to Telegram for in-app playback, and scheduled cross-posts to different time zones. Within 90 days they saw a 28% lift in same-day listens from Telegram and reduced manual posting time by 95% — showing automation both increases reach and reduces operational load.

Security, privacy, and developer best practices

Never hardcode your bot token; use environment variables or a secrets manager or a secrets service.
Sanitize HTML and scrub sensitive links from show notes before posting.
If you host private episodes behind auth, consider temporary signed URLs for Telegram to fetch files or pre-upload to Telegram using multipart upload.
Rate-limit outgoing requests to avoid impacting your origin host. Follow platform-specific security best practices when storing tokens and logs.

Monitor and iterate

Track these KPIs:

Post delivery success rate
Clicks on inline buttons (to measure traffic to website or sponsor links)
Listens started inside Telegram (proxy via play events or hosting analytics)
Subscriber growth on Telegram after automation launch

Starter templates & repo suggestions

Start with a simple repo that includes:

Feed poller (Node/Python)
Dedup store (SQLite or Redis)
Message formatter module (HTML/MarkdownV2 safe)
Uploader module for sendAudio and sendMessage
Scheduler for follow-ups and teasers

2026 trends to watch and future-proofing

In 2026 creators should watch:

Feed enrichment: more feeds will include structured chapter data and JSON-LD metadata making parsing more reliable.
Interoperability: bridges between ActivityPub-like systems and messaging apps could change discoverability; design your pipeline to accept alternate feed input sources and consider edge signals and live events when optimizing for discovery.
Privacy-first monetization: gated content and token-gated channels will evolve — implement modular gating in your bot early.

Troubleshooting quick reference

Bot can't post to channel: ensure it's an admin and you use the correct chat_id.
Audio fails to upload: check file size, content-type, and URL accessibility; try server-side download and multipart upload.
Timestamps missing: inspect the raw RSS for chapters or parse show notes with a more permissive regex.
Duplicate posts: ensure GUID or enclosure URL deduplication with persistent storage.

Final checklist before going live

Token and admin rights verified
Deduplication store seeded with existing episodes
Message formatting tested with long descriptions and edge-case characters
Retry/backoff and monitor alerts in place
Optional: audiogram generator tested for social cross-posting

Summary: An RSS-to-Telegram bot is high leverage — it increases episode discoverability, improves in-chat listening, and frees creators to focus on content. With structured parsing, smart uploads, and robust error handling you can run a reliable pipeline that scales with your audience.
