FAQ (Frequently Asked Questions)

What are the two options for when apex triggers can run?

There are two types of Apex triggers in Salesforce: Before Triggers and After Triggers. Before Triggers execute before the record is saved to the database, while After Triggers execute after the record has been saved.

Can apex trigger make a callout?

Even though there's the restriction of not allowing API callouts from triggers, there's a workaround to make it happen. You can use Asynchronous Apex to make callouts.

What is the limit of apex triggers in Salesforce?

Your Apex triggers (combined) must not exceed 200 SOQL queries per batch. If they do, your Clean job for that object fails. In addition, if your triggers call future methods, they're subject to a limit of 10 future calls per batch.
