Telegram ads conversion tracking: ad click flowing through a server postback to an analytics dashboard

Content owner: Adsun Editorial & Ad Operations Team · Last verified: 2026-10-18

Quick answer

To track conversions from Telegram ads, pass an identifier from the ad click to your landing page, bot or Mini App and record it when the user converts. For websites use UTM parameters plus a click ID; for bots use the /start deep-link parameter; for Mini Apps use the startapp parameter. Then report conversions back to your analytics — or via server-to-server (S2S) postback to your tracker — so each sale or sign-up is tied to the country, placement and creative that produced it.

Key takeaways

Every Telegram click needs an identifier that survives to the conversion.
Bots use /start parameters; Mini Apps use startapp; websites use UTM + click ID.
Server-to-server postbacks are more reliable than browser pixels inside Telegram.
Pick one attribution window and use it consistently when comparing placements.

Why Telegram tracking needs extra care

Links from Telegram open in the in-app browser or directly in a bot or Mini App, where third-party cookies and pixels often fail. Relying only on browser pixels under-counts conversions; passing identifiers through the URL and confirming conversions server-side keeps data accurate.

Tracking by destination

Website: add utm_source=telegram, utm_campaign and a click ID parameter; store them in your sign-up or order record.
Bot: use deep links like t.me/yourbot?start=campaign123 and save the parameter when the user starts the bot.
Mini App: use t.me/yourbot/app?startapp=campaign123 and read it from the Mini App launch data.
App stores: use your mobile measurement partner's tracking link as the ad URL.

How a server-to-server postback works

When a user clicks, your tracker generates a click ID and appends it to the landing URL. When the user converts, your server calls the tracker's postback URL with that click ID and, optionally, the revenue. Because the call is server to server, it does not depend on cookies or the in-app browser.

Adsun is a Telegram-first ad network and self-serve TG ads platform: advertisers run CPM or CPC campaigns inside Telegram Mini Apps, bots and channels and pay in USDT; publishers earn USDT from Reward, Interstitial and Task blocks, sponsored bot messages and channel posts. Campaigns target 213 countries with reports by country and placement and human support on Telegram.

Attribution windows and common mistakes

Use the same window (for example 7 days after click) when comparing campaigns.
Don't strip URL parameters in redirects — test the full click path before launch.
Deduplicate conversions so one user is not counted twice.
Record revenue, not just conversions, so you can calculate ROAS.

Metric definitions and formulas

CPM: Cost per mille: what an advertiser pays for 1,000 ad impressions.CPM = (Ad spend ÷ Impressions) × 1,000
CPC: Cost per click: average price an advertiser pays for one click.CPC = Ad spend ÷ Clicks
CTR: Click-through rate: the share of impressions that produced a click.CTR = (Clicks ÷ Impressions) × 100%
eCPM: Effective CPM: what a publisher earns per 1,000 impressions, whatever the pricing model.eCPM = (Publisher earnings ÷ Impressions) × 1,000
Fill rate: The share of ad requests that returned an ad.Fill rate = (Filled ad requests ÷ Total ad requests) × 100%

Worked example

Hypothetical example — not real Adsun data

An advertiser spends $300 on a CPC campaign at $0.05 per click = 6,000 clicks; 40% load the landing page = 2,400 visitors; 5% sign up = 120 users; 15% of them buy with an average first order of $40 = 18 buyers and $720 revenue. ROAS = 720 ÷ 300 = 2.4 (240%), cost per buyer ≈ $16.67. Replace every figure with your own data.

Adsun measurement methodology

Adsun counts an impression when an ad is rendered in a publisher block, a click when the user opens the ad destination, and a reward only after the server-to-server Reward URL confirms completion. Debug-mode traffic is excluded from billing and reports. Metrics are shown per platform, block and country in the partner and advertiser dashboards. Adsun does not publish aggregate network benchmarks in this guide; any number below marked “Hypothetical” is illustrative only. See the SDK documentation for integration details.

Frequently asked questions

Can I use a Facebook or Google pixel for Telegram ads?

You can keep them on your site, but pixels often miss conversions from Telegram's in-app browser. Use UTM parameters, click IDs and server-side events as your source of truth.

How do I track conversions in a Telegram bot?

Use a deep link with a start parameter (t.me/yourbot?start=CODE) as the ad URL and save CODE when the user presses Start; attribute later actions to it.

How do I track Telegram Mini App installs from ads?

Use the startapp parameter in the Mini App link and read it from the launch data when the app opens.

What is an S2S postback?

A server-to-server request your system sends to a tracker when a conversion happens, carrying the click ID so the conversion is attributed to the right ad.

Does Adsun support custom landing URLs with parameters?

Yes — you set your own landing URL per campaign, so you can add UTM parameters, click IDs or bot and Mini App start parameters.

Which attribution window should I use?

Seven days after click is a common starting point for apps and e-commerce; shorter for impulse offers, longer for high-consideration products. Stay consistent.

Why do my tracked conversions not match my sales?

Parameters lost in redirects, pixels blocked in the in-app browser, duplicate events or different attribution windows. Test the full flow with a real click.
