Checkout Solutions for Subscription Businesses

Transact Bridge provides three checkout solutions for collecting subscription payments. All options support recurring billing while allowing businesses to choose the integration approach that best matches their customer experience and technical requirements.

Payment Link

Generate a hosted subscription payment link and share it with customers via email, SMS, WhatsApp, or any other communication channel.

Iframe

Embed the Transact Bridge checkout directly within your website or application to provide a seamless in-app payment experience.

Drop in

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.
A hosted checkout page that can be generated using the Billing Session or Subscription APIs and shared with customers.

​
Business Use Cases

Payment Link is ideal for businesses that need the fastest integration or collect payments through email, SMS, WhatsApp, invoices, or other offline channels. Choose Payment Links when customers do not necessarily begin their journey from your website or when your sales process is assisted by your sales or support team.

​
2. Iframe

The Iframe Checkout SDK is a JavaScript-based iframe Payment SDK that allows merchants to easily embed the checkout experience directly inside their application or website without the customer leaving your platform.

​
Business Use Cases

Iframe Checkout is suitable for businesses that want to embed a secure payment form within their website with minimal implementation effort. Also, when maintaining your application’s branding and minimizing customer redirections are important.

3. Drop-in Checkout for Subscription Businesses

TBDropin is a JavaScript-based Drop-in Payments SDK that allows merchants to easily embed secure & PCI-compliant payment components into their applications. It provides pre-built payment elements with flexibility of styling them (UPI, Cards, T&C, etc.) and ensuring sensitive payment data never touches the merchant’s servers to adhere to compliances. With a simple script include and a few lines of JavaScript, merchants can:
  • Create their own checkout experience with pre-built payment components
  • Collect payment details securely without handling sensitive data on their servers
  • Trigger payments with a unified pay() API to handle all payment methods
  • Receive payment status updates through webhooks & SDK events for real-time processing ​

Business Use Cases

Drop-in Checkout is recommended for businesses seeking a highly customizable, seamless checkout experience with greater control over the customer journey, UI interactions, and subscription workflows.
