In-App Payments SDK: Android and iOS 1.5.4


In-App Payment SDK version 1.5.4 for Android and iOS includes an important update that mitigates the risk of SCA (Strong Customer Authentication) declining on payments made after October 31, 2021.

If you are using In-App Payment SDK version 1.5.2 or earlier, you must upgrade to 1.5.4 so that the SDK can perform SCA on payments.
