Changelog

This release improves the payment experience in two key areas: checkout renders faster, and the 3D Secure flow for card payments handles authentication results more clearly and reliably.

Checkout shows up faster

Previously, the SDK waited for a payment method update before rendering the checkout form. That round trip could add around 500 ms before the customer saw the form.

With rebill@1.17.39, checkout renders first, and that update runs only when the customer submits the payment, safely and in order.

Customers see the payment form sooner, without changing when the payment method is charged or skipping the bank verification step.

A better 3DS experience

We also improved the 3D Secure flow for cards in cases where a bank-approved authentication could be misinterpreted.

When a bank approves a 3DS authentication without showing a challenge, the SDK now correctly recognizes that response as a valid approval.

And when a challenge is required, the iframe now allows biometric authentication and passkeys when supported by the bank.

How to use it

Update the rebill package to version 1.17.39.

There are no breaking changes and no integration changes required.

Available in: rebill@1.17.39

npm install rebill@1.17.39

This release improves how checkout captures the buyer's location, giving each new payment more accurate regional information for payment operations, price selection, and risk evaluation.

More context for every payment

We've improved how the SDK determines the country associated with each payment based on the buyer's location.

This gives different parts of the payment experience more accurate regional information:

• The country available in each payment's details.

• Price selection for multi-currency products and plans.

• Context used during risk evaluation.

The country determined for each transaction is available in the country field of GET /v3/payments and in the payment details.

A more accurate multi-currency experience

For products or plans with prices configured in multiple currencies, price selection depends on the buyer's location.

The SDK now uses more accurate regional context to determine which price applies to each customer. This allows buyers across different markets to access the price configured for their currency when available.

If you use multi-currency pricing, we recommend reviewing your configuration before updating to make sure each market has the expected pricing.

Products with a single price or fixed pricing are not affected.

We recommend updating

To take advantage of this improvement on new payments, we recommend updating the SDK.

Payments created before this update won't change and will keep the information they were originally recorded with.

No integration changes required

There are no new properties or changes to callbacks, events, or response structure.

You only need to update the SDK version to start using the new behavior.

Available in: rebill@1.17.38

npm install rebill@1.17.38

This release brings together the improvements introduced from rebill@1.17.34 through 1.17.37, with updates that make checkout clearer, validations more reliable, and provide more context for fraud prevention.

Improvements included

• More context to prevent fraud in card payments
  We strengthened how device information is preserved throughout card payment flows in Argentina, across different payment scenarios. This allows each transaction to be evaluated with more complete fraud prevention context, improving risk assessment accuracy and reducing declines caused by missing information.

• Clearer financing information for CLP and COP
  The interest disclaimer now appears only when customers select 2 or more installments. We also updated the message to clarify that any applicable interest is determined and charged by the issuing bank.

• More accurate messages when a QR cannot be generated
  Bank transfer payments now show a specific error when the QR cannot be generated, instead of incorrectly communicating that the payment was declined.

• Immediate validation of prefilled data
  Fields that arrive with prefilled information are now validated as soon as checkout starts. This helps detect invalid data earlier and prevents a submission from being blocked without communicating the error to the integration.

No integration changes required

All these improvements apply when you update the SDK and are fully compatible with existing integrations.

There are no changes to properties, callbacks, events, or integration responses. There are no breaking changes or additional actions required.
