# Salesforce Scheduler Apex Classes

Salesforce Scheduler provides the `ConnectApi` namespace (also called Connect in Apex) and `LxScheduler` namespace that contains classes for accessing the same data available in the Salesforce Scheduler Business APIs.

You can use these apex classes as an alternative to the Salesforce Scheduler Business APIs to simplify appointment scheduling in Salesforce. For example, use the `createServiceAppointment(createServiceAppointmentInput)` method of the `ConnectApi` namespace as an alternative to the `service-appointments` Connect API to create service appointments.

**note:** Salesforce Scheduler is built on the Salesforce platform (also known as Lighting Experience). The Salesforce platform specific Apex governor limits apply to the Salesforce Scheduler Apex classes and methods requests. For more information on the Lightning platform Apex governor limits, see [Apex Governor Limits](https://developer.salesforce.com/docs/atlas.en-us.salesforce_app_limits_cheatsheet.meta/salesforce_app_limits_cheatsheet/salesforce_app_limits_platform_apexgov.htm) in Salesforce Developer Limits and Allocations Quick Reference.

The following table lists the available Salesforce Scheduler Apex methods, as well as the corresponding Connect REST API.
