Apex Triggers
Apex Triggers is a Setup page that lists all Apex triggers in the org along with their associated objects, API version, and status (Active or Inactive).
Definition
Apex Triggers is a Setup page that lists all Apex triggers in the org along with their associated objects, API version, and status (Active or Inactive). Triggers are pieces of Apex code that execute before or after data manipulation events like insert, update, delete, and undelete on Salesforce records.
In plain English
“Here's a simple way to think about it: Apex Triggers is the list of every code hook that fires when records change. Each trigger is bound to a specific object (Account, Contact, custom) and runs before or after inserts, updates, or deletes - automating logic that can't be expressed in Flow.”
Worked example
The developer at NexGen Logistics opens the Apex Triggers page in Setup to review all triggers in the org. She finds a trigger on the Order object called "OrderValidation" that is causing unexpected behavior. She clicks to view the code, identifies a logic error in the before-update context, and deactivates the trigger temporarily while she deploys a fix.
Why Apex Triggers is the page that lists every react-to-record-change hook
An Apex Trigger is code that runs automatically when a record on a specific object is inserted, updated, deleted, or undeleted. Apex Triggers is the Setup page that lists every trigger in the org, the object it's bound to, the API version it targets, and whether it's currently active. For an admin debugging why a record's update behavior changed, this list is one of the first surfaces to check.
The reason it earns more attention than its volume suggests is that triggers compound. A field update from one trigger fires another trigger; multiple triggers on one object run in non-deterministic order; a trigger that worked fine for years can start misbehaving when data volumes change. Audit triggers periodically with the dev team, consolidate where possible (the Trigger Handler pattern is a common best practice), and document each trigger's intent - the next person to debug them will thank you.
How to set up Apex Triggers
Apex Triggers is the Setup page listing all Apex triggers in the org — what objects they fire on, what events (insert / update / delete / undelete / before / after), and their active state. Like Apex Classes, most modern orgs deploy triggers from outside Setup.
- Open Setup → Apex Triggers
Setup gear → Quick Find: Apex Triggers → Apex Triggers.
- Review the list of triggers
Each row: Name, Object, Active, Last Modified.
- Click into a trigger for source
Source includes the trigger declaration: trigger MyTrigger on Account (before insert, after update) { ... }
- For deactivation: click Edit → tick Inactive
Inactive triggers don't fire. Useful for emergency stop while debugging.
- For coverage: click Show Coverage
Each line shown as covered / uncovered / N/A. Production deploys require ≥75% coverage on changed Apex.
- Show Dependencies for impact analysis
Lists what references this trigger before deletion / refactor.
Active triggers fire; Inactive sits on the shelf.
Locked to a Salesforce API version. Bump carefully.
before/after × insert/update/delete/undelete. Each combo handled separately in the trigger body.
- Order of trigger execution matters. Multiple triggers on the same object fire in alphabetical order — without a Trigger Handler pattern, you get unpredictable execution.
- Inactive triggers don't fire but the trigger code is still in the org. To remove permanently, deploy with the trigger removed via Change Set / DX.
- Apex Triggers run after Validation Rules, after before-save Flows, and before after-save Flows. Knowing the order helps debug "why didn't my trigger see this update."
How organizations use Apex Triggers
Audit pass on Apex Triggers consolidated 14 fragmented triggers on Opportunity into a single Trigger Handler class - eliminating ordering issues that had caused intermittent bugs for years.
Migrated trigger-based field updates to Flow where business logic was simple, leaving complex async work in Apex Triggers - clearer separation of concerns.
Compliance reviews surface every active trigger and its purpose; auditors confirm none of them silently overrides regulatory validation.
