Trigger isn't running after Custom Object Insertion from REST API

Question

I'm having some issue with having a trigger run after inserting an object from a Rest API call. I've confirmed that the object is being created, and I've tested the other sections of the code manually and they are fine.

Here's my code

Sensor_Event__c event = new Sensor_Event__c();
event.JSON_Event__c = requestBody.toString();
insert event;

(I've checked and the object has the correct event with the correct string)

Here's my trigger

trigger ProcessSensorEvent on Sensor_Event__c (after insert) {
    
        for(Sensor_Event__c event : Trigger.new) {
            SensorsHandler.SensorEvent sensorEvent = new SensorsHandler.SensorEvent();
            sensorEvent = SensorsHandler.parseSensorJSON(event.JSON_Event__c);
            SensorsHandler.generateMonitorFromEvent(sensorEvent);
        }
   
}

I've tried inserting the same object from the exernal rest API in manually and the trigger code runs properly, and the object is created by the rest api without issue, but when the object is created by the REST API, the trigger doesn't run. Any help would be appreciated.

When a record is inserted and you can see it in the database, then it is guaranteed the trigger ran.

Now, you might not see the effects of the trigger for several reasons

• The trigger is coded to not do anything for the given running user
• The trigger is coded to not do anything given the presence of certain metadata like Custom Settings
• The trigger actually runs, perhaps delegating to helper classes and because of sharing rules for the running user, no related records are being retrieved so loops fall through and process zero records

Since your example has the request coming from an external source, check which user is the running user and examine the debug logs for that user to gain insight
