Apex Reference Guide

Apex is a strongly typed, object-oriented programming language that allows developers to execute flow and transaction control statements on the Salesforce Platform server, in conjunction with calls to the API. This reference guide includes built-in Apex classes, interfaces, enums, and exceptions, grouped by namespace. It also includes Apex DML statements to insert, update, merge, delete, and restore data in Salesforce.
For information on the Apex development process, see Apex Developer Guide.

In API version 51.0 and earlier, Apex Reference information was included in the Apex Developer Guide in the Apex Language Reference section.
