Why Apex Triggers Matter in Salesforce Salesforce is built around clicks but at some point, you need code When business processes become complex, automation tools like Flow or Process Builder cannot handle everything. That’s where triggers come in. Triggers help you: Validate data before saving Update related records Automate complex backend tasks Integrate external systems Maintain data consistency In simple words, triggers help Salesforce behave the way your business needs. What Exactly Is an Apex Trigger? A trigger is a piece of Apex code that runs automatically when a record is inserted, updated, deleted, restored, or undeleted. Salesforce groups these as Trigger Events, and they occur in two phases:
Before Events (actions before data is saved) After Events (actions after data is saved) Examples of Trigger Events: before insert before update after insert after delete after update Now that you know what triggers are, let’s create one. How to Produce Triggers in Salesforce Development (Step-byStep) Step 1: Go to the Object Where You Want the Trigger Example: Let’s create a trigger on the Account object. Navigation Path: Setup → Object Manager → Account → Triggers Click New. This opens the Apex Trigger Editor. Step 2: Understand the Trigger Template
Salesforce provides a simple template: trigger Name on Object Name (trigger events) {} Simple, right? Now, let’s add real logic. Step 3: Write Your First Apex Trigger (Beginner Example) Example 1: Basic Salesforce Trigger Example Automatically set the Account’s Rating to “Hot” if the Annual Revenue > 1M. trigger SetRatingOnAccount on Account (before insert, before update) {for (Account acc : Trigger. New) {if (acc.AnnualRevenue > 1000000) { accreting = 'Hot';} }} What’s happening here: Trigger runs on before insert and before update It loops through incoming Account records If Annual Revenue > 1M → Rating becomes Hot This is the simplest way to understand how to create triggers in Salesforce development with example.
