# Overview

# Checkout Solutions

Transact Bridge offers three checkout integration options to suit different business requirements: **Payment Link, Iframe, and Drop-in Checkout**. These solutions provide flexibility in how merchants integrate payments, from a simple redirection-based flow to an embedded checkout experience within their website or application.

> [card] Payment Link
>
> Redirection-based
>
> Payment Link is a simple redirection-based payment integration that allows merchants to generate a hosted checkout page using the Billing Session or Subscription APIs and share the payment link with customers via email, SMS, WhatsApp, or other communication channels.
>
> When customers open the link, they are **redirected to the Transact Bridge-hosted checkout page** to complete the payment.
>
> > [!NOTE]
> >
> > **Minimal development effort:** This integration requires minimal development effort and does not require embedding a checkout interface into the merchant's website or application, making it ideal for quick payment collection.

> [card] Iframe
>
> Seamless checkout
>
> Embed the Transact Bridge checkout directly within your website or application to provide a seamless in-app payment experience.
>
> Unlike Payment Link integration, **Iframe does not redirect customers to a separate checkout page**. Instead, the checkout is displayed within your website or application, allowing customers to complete their payments without leaving the current page. This provides a smoother and more consistent checkout experience.

> [card] Drop-in Checkout
>
> Customizable
>
> The **Drop-in Checkout** solution provides greater flexibility and customization compared to a traditional iframe integration.
>
> While both options allow customers to complete payments without leaving your website, Drop-in Checkout offers **tighter integration with your application's user experience**.
