Manage Apex Triggers

Triggers are stored as metadata in Salesforce. A list of all triggers in your organization is located on the Apex Triggers page in Setup. Triggers are also associated and stored with specific objects and are listed in the object management settings for each object. For additional development functionality, use the Developer Console.

You can add, edit, or delete Apex using the Salesforce user interface only in a Developer Edition organization, a Salesforce Enterprise Edition trial organization, or sandbox organization. In a Salesforce production organization, you can change Apex only by using the Metadata API deploy call, the Salesforce Extensions for Visual Studio Code, or the Ant Migration Tool. The Salesforce Extensions for Visual Studio Code and Ant Migration Tool are free resources provided by Salesforce to support its users and partners, but are not considered part of our Services for purposes of the Salesforce Main Services Agreement.

• A icon indicates that an Apex trigger is in an installed managed package. You cannot edit or delete a trigger in a managed package.
• A icon indicates that an Apex trigger in a previously released managed package will be deleted on the next package upload. You can choose to undelete the Apex trigger through the package detail page.

Note The namespace prefix is added to Apex classes and triggers, Visualforce components and pages, brand templates, folders, s-controls, static resources, web links, and custom report types if they are included in a managed package. However, if you don't have customize application permissions, the namespace prefix field is not displayed for brand templates, folders, and custom report types.
