# Initialization

Configure and initialize the Data 360 Module for the Engagement Mobile SDK before using it to invoke web services. Use the configuration builder to provide required settings, such as `appId` and `endpoint`, from your Mobile Connector.

The Engagement Mobile SDK currently supports two major versions: [Version 3.x](https://developer.salesforce.com/docs/data/data-cloud-engagement-mobile-sdk/guide/c360a-api-engagement-mobile-sdk-initialization-v3.md) and [Version 2.x](https://developer.salesforce.com/docs/data/data-cloud-engagement-mobile-sdk/guide/c360a-api-engagement-mobile-sdk-initialization-v2.md). To take advantage of the latest features and improvements, upgrade to Version 3.x.
