Changelog

v1.0.20

This release includes breaking changes. The notification log and stored payment method types now match what the API returns, and OCR results have new amount fields. See September 22, 2026, September 29, 2026, October 1, 2026, October 2, 2026, and October 5, 2026 for more information.

Notification log retry methods return new types

notificationlogs().retryNotificationLog now returns NotificationRetryResponse, which has a single getMessage() method, instead of NotificationLogDetail. notificationlogs().bulkRetryNotificationLogs now returns String instead of void. The async and raw clients have the same changes.

// Before
NotificationLogDetail log = client.notificationlogs().retryNotificationLog("UUID");
// After
NotificationRetryResponse retry = client.notificationlogs().retryNotificationLog("UUID");
String message = retry.getMessage();
String bulk = client.notificationlogs().bulkRetryNotificationLogs(Arrays.asList("UUID"));

Notification log types share a new base interface

NotificationLog and NotificationLogDetail now both implement the new INotificationLogBase interface, and there’s a new NotificationLogBase class. NotificationLogDetail no longer implements INotificationLog.

• getResponseStatus() now returns String instead of Optional<String>. It holds a status message such as OK. The HTTP status code is in getResponseStatusCode().
• On NotificationLogDetail, getResponseContent() now returns String instead of Optional<String>.
• Both types add the required getOrganizationName(), getPaypointName(), getRequestId(), and getResponseStatusCode() (int).
• NotificationLog adds the required getNotificationType(), getOrganizationLogo(), getOrganizationFavIcon(), and getPaypointLogo().

The new required fields are new builder stages, so existing builder() calls for these types must set them.

Customer fields on stored payment methods

GetMethodResponseResponseDataCustomersItem no longer implements IPayorDataRequest, and the IPayorDataRequest interface has been removed. getFirstName() and getLastName() are now getFirstname() and getLastname().

New response fields

• AddMethodResponse adds getPageIdentifier(), and AddMethodResponseResponseData adds getAuthCode(), getAvsResponseText(), getCvvResponseText(), and getVendorId().
• GetMethodResponseResponseData adds getWalletType().
• OcrResultData adds getTotalAmount() and getDiscount() (Optional<Double>).
