Upgrading from SDK 3

Introduction

Although SDK 4 contains important under-the-hood changes, we have intentionally kept the integration very similar to SDK 3.

This means that you can upgrade from 3.x to 4.x with minimal code changes (or quickly roll back to 3.x, should the need arise).

📘

Placement codes used for SDK 3 can be used with SDK 4. No new codes are required.
