What It Is

Custom Domain Payment Platform: Your Checkout, Your Domain

A custom domain payment platform allows merchants to deploy a fully functional payment checkout directly on their own website domain — rather than redirecting buyers to a third-party payment page. This preserves brand trust, reduces checkout abandonment, and keeps the buyer on the merchant's domain throughout the purchase.

PayBito enables this through its Domain Whitelisting feature under Developers → Domain Whitelisting at trade.paybito.com. Merchants add their authorised domains to the whitelist, generate named API keys, and embed the PayBito checkout button or payment link on their website — accepting Stripe card payments, PayPal, and 10+ crypto assets without the buyer ever leaving the domain.

Accept Stripe cards, PayPal REST API, and 10+ crypto assets on your domain
Configurable checkout profiles: payment methods, fees, buyer fields, discounts, redirects
Webhooks deliver payment events to your domain's server endpoint in real time

Why Custom Domain Checkout Matters

Domain Security via WhitelistingWithout domain whitelisting, any website could embed your merchant checkout. PayBito's Domain Whitelisting restricts checkout loading to only your authorised domains — preventing checkout hijacking and phishing abuse.

Brand Trust & ConversionBuyers who stay on your domain throughout checkout convert at higher rates. A custom domain checkout eliminates the redirect break that causes buyers to question payment legitimacy.

Per-Domain API Key ScopingGenerate separate named API keys for each domain integration. If a key is compromised, delete it without disrupting other domains or integrations — minimal blast radius per domain deployment.

Real-Time Events on Your ServerWebhook endpoints receive payment success, failure, and refund events from your domain's checkout in real time — enabling automated fulfilment, access provisioning, and accounting workflows on your own servers.

Domain Setup Components

Three Components That Enable Custom Domain Payments

Domain Whitelisting, API key management, and checkout configuration work together to create a secure, branded payment experience on your domain.

Domain Whitelisting

Domain Whitelisting under Developers restricts your embedded PayBito checkout to loading only on the domains you explicitly authorise. Add subdomains, staging environments, and production domains independently.

API Key Authentication

Named API keys authenticate your domain-embedded checkout with the PayBito platform. Each key can be named after its intended use (e.g. “production-website”, “staging”) and deleted independently without disrupting other integrations.

Checkout Embed Configuration

Create payment links under Get Paid → Create Payment and deploy them as embeddable buttons on your domain. Each link carries its full checkout profile — payment methods, fees, fields, discounts, and redirect URLs.

Setup Guide

Deploy a Custom Domain Payment Checkout in Four Steps

From dashboard configuration to a live checkout on your domain — the entire setup takes under 15 minutes.

Whitelist Your Domain

Navigate to Developers → Domain Whitelisting. Add your production domain and any subdomains you want to authorise.

Generate API Keys

Go to Developers → API Keys. Enter a name for your domain integration and click Create. Copy the publishable key for frontend use.

Create Payment Link

Build your checkout under Get Paid → Create Payment. Configure payment methods, fee profile, buyer fields, and success redirect to your domain.

Embed & Go Live

Deploy the button or link on your whitelisted domain. Configure webhooks to your server endpoint for automated payment event handling.

Platform Features

Every Feature a Custom Domain Payment Platform Needs

PayBito gives merchants a complete custom domain payment infrastructure — domain security, API authentication, configurable checkout, and event automation — without managing a separate payment gateway or processor relationship.

Explore the Platform

Domain Whitelisting Prevents Checkout Hijacking

Your embedded checkout button is cryptographically tied to the domains you whitelist. Any attempt to embed your checkout on an unauthorised domain is blocked at the platform level — protecting your brand and buyers from phishing.

All Three Payment Channels on Your Domain

Stripe card processing (via your pk_live_ / sk_live_), PayPal REST API (via your Client ID + Secret), and crypto (Brand Wallet, MetaMask, Trust Wallet, Coinbase, Phantom, Brave, TronLink, Guest Checkout) all load on your domain with a single embed.

Subscription Billing on Your Domain

Create recurring subscription payment links that load on your domain checkout. Buyers complete the subscription setup on your URL, and PayBito handles the renewal billing cycle — firing webhook events to your server on each renewal.

Redirect Back to Your Domain After Payment

Configure success, failure, and cancel redirect URLs in your Redirect profile to point back to specific pages on your domain — keeping the buyer journey entirely on your site from checkout initiation to order confirmation page.

Per-Domain Transaction Analytics

All transactions from your domain-embedded checkout appear in the Transactions dashboard with full detail — Payment ID, method, network, amount, and status. Filter by payment method or currency and export CSV for domain-specific reporting.

Sub-Domain Team Access Controls

Assign sub-merchant accounts with access to the Transactions, Analytics, or Configuration modules for specific domain deployments. Frontend teams can manage checkout profiles without accessing API credentials or settlement accounts.

Payment Methods

Every Payment Method Available on Your Custom Domain

Enable all three payment channels simultaneously or configure different methods for different checkout pages on your domain.

💳

Stripe — Card Payments

Accept Visa, Mastercard, and Amex on your domain via your Stripe API keys. Card checkout loads within your domain's checkout embed — buyers never see a Stripe-hosted page.

VisaMastercardAmexOne-TimeRecurring

🅿️

PayPal — Digital Wallet

Offer PayPal Balance and Pay Later to buyers in 200+ countries via your PayPal REST API Client ID and Secret. PayPal completes inline within your domain's checkout flow.

₿

Crypto — 10+ Assets

Accept BTC, ETH, USDT, USDC, and 6 more assets on your domain. Buyers pay via Brand Wallet, connect MetaMask, Trust Wallet, Coinbase, Phantom, Brave, TronLink, or use Guest Checkout.

Platform Comparison

PayBito Custom Domain vs Hosted Checkout Redirects

Hosted checkout pages take buyers off your domain and onto a third-party URL — reducing trust and increasing abandonment. Custom domain checkout keeps buyers on your site.

Why PayBito

Built for Merchants Who Need Payments on Their Own Domain

PayBito's custom domain infrastructure combines domain security, API-driven configuration, and multi-method payment support into a single platform without requiring separate processor integrations.

Security at the Domain Level

Domain whitelisting ensures your checkout button only activates on your authorised URLs. Even if your embed code is copied, it cannot process payments on an unauthorised domain.

BYO Stripe & PayPal

Your Stripe and PayPal credentials are yours — payments flow to your processor accounts. PayBito orchestrates the checkout on your domain without becoming an intermediary for your card or PayPal revenue.

Crypto Natively on Your Domain

10+ crypto assets, 6 external wallets, and Guest Checkout all deploy on your domain with the same button embed. No separate crypto gateway, no additional integration — all three channels in one checkout configuration.

Buyer Journey Stays on Your Site

Success, failure, and cancel redirects all point back to pages on your domain. Buyers experience a complete purchase journey without ever leaving your URL, improving trust and reducing abandonment.

Real-Time Events on Your Server

Webhooks deliver payment events to your domain's server endpoint instantly — enabling automated order fulfilment, SaaS provisioning, access control updates, and email notifications triggered by payment outcomes.

All Transaction Data, One Dashboard

Every payment from your domain checkout appears in the Transactions dashboard. Filter by method, network, currency, or status. Export CSV for domain-specific revenue reporting and reconciliation.
