Mobile SDK 4 Migration Guide

Mobile SDK 4 introduces a new architecture based on version 2 of our transactions API.

Migrating to Mobile SDK 4 consists of two separate parts:

  • Migrating your backend integration from transactions API v1 to v2
  • Migrating your mobile app from Mobile SDK 3.x to Mobile SDK 4

These migrations can largely be performed independently.

Prerequisites

We currently support the following payment methods in Mobile SDK 4:

  • Credit and debit cards
  • Apple Pay
  • Google Pay
  • PayPal
  • PostFinance Pay
  • Twint

While additional payment methods are planned for upcoming releases, migration is currently only possible if the payment methods you require are already supported.

Mobile SDK 3.x continues to be supported alongside Mobile SDK 4.
