Description

Filter out Personally-Identifying Information (PII) from the events sent to a Destination that shouldn't receive or store PII

1. Drops the PII if the denylist includes PII
2. Returns the updated event

Code Block

export function transformEvent(event, metadata) {

       const denylist = ["email", "phone"]; 
       const context = Object.keys(event.context);
       const traits = Object.keys(event.context.traits);
       denylist.forEach(key => {
       if(context.includes(key)) delete event.context[key]; 
       if(traits.includes(key)) delete event.context.traits[key]; 
       });
       return event; // return an updated event
}
