Salesforce Apex Triggers: Connecting Minds, Creating Futures

Supercharge Your Salesforce!
Salesforce Apex Triggers enable companies to be flexible in the fast-paced global market of today, maintain data veracity, and streamline processes.
How Do Apex Triggers Occur?

Apex Triggers are event-driven script segments that run in response to particular Salesforce occurrences. These events can be platform-related (like user login or platform events) or record-related (like record insert, update, or delete).

Why Do They Matter?

  • 1. Automation: You can automate procedures without requiring human interaction by using Apex Triggers. For instance, you can automatically update associated data or send notifications upon the creation of a new opportunity.
  • 2. Data Integrity: By enforcing business rules, triggers contribute to the maintenance of data consistency. It is possible to stop invalid data from being saved.
  • 3. Custom Logic: Apex triggers let you create custom logic, in contrast to workflow rules or process builders. This adaptability is very useful in complicated situations.

What is Apex?

Salesforce created Apex, a programming language that is object-oriented and tightly typed. It is an effective tool for improving Customer Relationship Management (CRM) systems and developing Software as a Service (SaaS) applications.

Let’s examine the salient features of Apex:

  1. Integration with Salesforce Servers:
  • Developers can run flow and transaction control statements on Salesforce servers directly using Apex.
  • It facilitates easy interaction with Salesforce data and procedures by working in tandem with API requests.
  1. Java-Like Syntax:
  • Developers are accustomed to Apex syntax because it bears resemblance to Java.
  • Components like object notation, conditional statements, loops, and variable declarations are present.
  1. Improvement of Business Logic
  • Custom business logic can be added by developers to a variety of system events, such as button clicks.
  • Updates on related records,
  • Visualforce pages,
  • Object triggers or web service requests can start apex triggers.
  1. Built-in support: 
  • Apex offers built-in support for Lightning Platform idioms, including Data Manipulation Language (DML) operations like INSERT, UPDATE, and DELETE, with exception handling for DmlExceptions.
  • Queries written in Salesforce Object Search Language (SOSL) and Salesforce Object Query Language (SOQL).
  • Looping for processing several records in bulk.
  • Custom public API calls constructed from Apex methods that are stored.
  1. Strict and Aware of Multiple Tenants:
  • Apex uses direct references to schema objects (such as object and field names) and is tightly typed. When compiling, it fails rapidly if any references are invalid.
  • Apex operates in a multitenant environment, protecting against resource monopolization and runaway code, just like the rest of the Lightning Platform.


Apex gives developers the ability to improve Salesforce functionality, automate procedures, and design unique solutions. Anyone involved in the Salesforce ecosystem will find it to be a useful resource.

Apex Trigger Best Practices:-

  • 1. Bulk-Friendly Code:  When handling bulk data, always write triggers. Steer clear of DML statements and SOQL queries inside loops.
  • 2. Selective inquiries:  Tune your inquiries to only bring up the information you need. Employ WHERE clauses wisely.
  • 3. Trigger Handlers:  To maintain your triggers organized and modular, think about utilizing trigger handlers (different classes).
  • 4. Test Coverage:  To guarantee trigger functionality and coverage, create thorough unit tests.
  • 5. Governor restrictions: Recognize the governor restrictions on Salesforce. Create triggers that adhere to these restrictions.

Practical Use Cases:-

  • 1. Lead Conversion Automation: Upon the conversion of a Lead, automatically generate Contacts and Opportunities.
  • 2. Field Updates: Modify linked records in response to modifications made to a parent record.
  • 3. Approval Procedures: Subject to certain requirements, initiate the approval procedures.
  • 4. Integration Points: When specific events take place, call upon external APIs or services.
  • 5. Custom Notifications: Notify users or outside systems in a way that suits them.

Typical Situation: Greetings via Email

Assume for the moment that you wish to greet newly added Contacts with an email.
On the Contact object, you may define an after insert trigger.
The trigger activates when a Contact is inserted, allowing you to send the email using Apex.

Start the On Contact, send a welcome email (after insert) Emails in the list are created using new List(); for (Contact newContact : { Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage(); email.setToAddresses(new List{newContact.Email}); email.setSubject(‘Welcome to Our Community!’); email.setPlainTextBody(‘Dear’+ newContact.FirstName + ‘,\n Welcome aboard!’); emails.add(email); } Messaging.sendEmail(emails); }
