Base44 SDK Adds a Payments Module for One-Time Payments and Subscriptions

Base44View original changelog

Base44's SDK now includes a payments module that lets apps accept one-time payments and subscriptions through Stripe, PayPal, or Base44 Payments. Frontend methods render embedded checkouts and look up the current user's purchases. Service-role methods, called from backend functions, create checkouts, list any buyer's purchases, refund payments, and manage subscriptions.

Key Takeaways

  • The SDK's new payments module covers both one-time payments and subscriptions from a single API.
  • It works with three providers: Stripe, PayPal, and Base44 Payments.
  • Frontend methods render embedded checkouts directly in the app.
  • The current user's purchases can be looked up from the client, so apps can show purchase history without custom plumbing.
  • Creating checkouts, listing any buyer's purchases, refunding, and managing subscriptions are service-role methods called from backend functions.
  • Keeping refunds and subscription changes on the service role keeps sensitive money operations server-side.

Selling inside an app, from code

Base44's SDK now includes a payments module. Apps can use it to accept one-time payments and subscriptions through Stripe, PayPal, or Base44 Payments. Developers get one SDK surface for charging customers, whichever of the three providers the app uses.

Frontend methods

The client-side methods cover the buyer's side of the flow. They render embedded checkouts inside the app and look up the current user's purchases, so an app can show a buyer what they have bought without a custom backend endpoint.

Service role methods

The privileged operations sit behind the service role and are meant to be called from backend functions. They can:

  • Create checkouts.
  • List purchases for any buyer.
  • Refund payments.
  • Manage subscriptions.

Keeping these on the service role means money-moving actions stay on the server and are not exposed to browser code.

Where to find the details

The payments reference in the SDK documentation lists every client and service-role method.
