Connecting custom domains and subdomains via Cloudflare for tracking links, landing pages, and event tracking in Tracker.
Tracker → Domains is an infrastructure section used to connect domains for campaign operations. Without an added domain, the Domain field in Information — Basic Campaign Identification will remain unavailable, and the campaign cannot be saved.
Chatterfy does not sell domains and does not manage registrations: you must purchase a domain from a registrar, connect it via Cloudflare, and only then add it to Tracker.
What the Domains section allows
Domains allows you to configure: tracking links on your own domain, landing pages and funnel transitions, specific subdomains for offers, GEOs and teams, HTTPS and SSL via Cloudflare, and access management for domains between media buyers and teams — see Buyers — Buyers and Team Leads.
A typical sequence looks like this:
domain → Cloudflare → landing page → Telegram → events and analytics.
If you skip one of the setup stages, you usually encounter issues such as:
SSL did not activate
the browser displays an insecure connection warning
tracking link does not open

Why Cloudflare is needed

Cloudflare is used as a DNS proxy between your domain and Chatterfy infrastructure.
It is used to configure:
DNS records
SSL certificates
HTTPS
proxying and basic traffic protection
For most scenarios, the free Cloudflare plan is sufficient.
The target DNS record for integration with Tracker is a CNAME to:
tracker.chatterfy.ai
Cloudflare handles the following:
tracking link opens
landing page loads
user transitions
some server requests and events
Without proper SSL and DNS, ad networks and browsers may restrict transitions.


What can be connected

Apex domain

The main domain without a subdomain.
Examples:
example.com · mybrand.io
Suitable if:
you are launching infrastructure from scratch
you need a separate brand
an affiliate program requires a separate domain
you want to completely isolate the offer

Subdomain

An additional address within the main domain.
Examples:
us.example.com · de.example.com · promo.example.com
Suitable if:
the main site is already running on apex
you need multiple entry points for GEOs or offers
you are testing different funnels
you want to separate teams and traffic
Subdomains are usually easier and cheaper to maintain: one domain can be used for dozens of separate scenarios.

When to use a domain vs a subdomain

Situation
What to choose
First launch, no domain yet
New domain
The main domain already has a site
Subdomain
Multiple offers or GEOs
Multiple subdomains
Need full isolation
Separate domain
Quick test
Subdomain
One domain can be used simultaneously in several Tracker campaigns.


How the setup works

Connecting a domain is not a single step, but a sequence of settings between Cloudflare and Chatterfy.

For a new apex domain

Setup sequence:
How to add a domain to Cloudflare → How to Set Up SSL → How to add a domain in Chatterfy

For a subdomain

If the primary domain is already connected to Cloudflare:
How to add a subdomain → How to Set Up SSL → How to add a domain in Chatterfy
gicon:TriangleAlert
Менять порядок нельзя
Without Cloudflare, Tracker will not verify the domain. Without SSL, redirects may be blocked. Without adding it to Chatterfy, the domain will not appear in Campaigns.
In this case, you usually do not need to change nameservers at the registrar — a new DNS record inside Cloudflare is sufficient.


Why the domain must be added to Tracker first

Once connected, the domain is used by the system for: tracking links, landing pages, redirects, event tracking, branded URL, and shortened links via Bot Variables in AI Prompts.
All user clicks pass through your domain rather than the platform's technical address.

One domain or multiple

Small team

Usually sufficient:
one primary domain
2–3 subdomains for GEO
Example:
us.example.com · de.example.com

Multiple media buyers

Usually, they use:
separate subdomains per team
separate domains for risky offers
This allows you to isolate traffic and restrictions.

Agency model

You can connect a separate branded domain for each client.


Which domains are suitable

Tracker usually has no restrictions on domain zones.
Restrictions more often arise from:
Cloudflare
ad networks
affiliate programs

Most common zones

Zone
Features
.com / .net / .org / .io
Most versatile
.de / .us / .uk
GEO-oriented
.xyz / .site / .online
Cheap, but sometimes cause more checks
When choosing a domain, consider the requirements of ad platforms and affiliate programs.

Linking domains to buyers

In Domains, you can restrict access to domains for individual users and teams.
This is convenient if:
the team has many domains
different buyers work with different offers
infrastructure isolation is needed

FAQ

The limit depends on your plan and account policy. Check the restrictions with Chatterfy support.

Yes. You need to:
transfer DNS to Cloudflare
delete conflicting records
create a CNAME for tracker.chatterfy.ai

After SSL is active and the domain is added to Chatterfy, it usually takes from several minutes to several hours for DNS propagation.

For most tracking scenarios — yes.

For the full Cloudflare setup, DNS delegation via nameservers is usually required.

A domain is typically linked to one Chatterfy organization. For multi-tenant scenarios, please check restrictions with support.
