Platform triggers limits

Platform triggers work on both standard and custom objects, making the feature a powerful tool for streamlining work processes. Some differences in functionality exist when creating triggers for standard objects versus custom objects, though. Read on to understand these differences so that you can create the triggers needed for your use case.

Related Records

You can run triggers on related records for both standard and custom objects. However, for standard objects, you can only run triggers on one-to-one relationships. This limit to one-to-one relationships affects the Update field value and Run triggers on related records trigger types. Triggers on custom objects can be run on one-to-many relationships.

Maximum number of triggers

Standard objects can have a maximum of 30 triggers per object. Custom objects have no trigger limit.
