# How To Write Custom Blackthorn Compliance Apex Triggers

Blackthorn Compliance comes with native Apex Triggers on select standard objects included in the Compliance package. But if you want to use your own triggers instead, you simply need to change the Manager field "Use Own Trigger". This field controls whether or not Compliance will execute its native triggers. In other words, you can override our apex triggers on: Case, CaseComment, Task, EmailMessage, LiveChatTranscript, FeedItem, FeedComment, Attachment, and ContentVersion.

**Important:** If you are writing triggers on a Salesforce object not included in the Compliance package, you do not need to check the field `Use Own Trigger`.

1. Navigate to the Manager Setting for the standard object, Setup > Develop > Custom Metadata Types > Manager > Manage Records > Click on the object name.
2. Press **Edit**. ![manager detail edit](https://cdn.document360.io/f977eec0-500f-40a3-b663-724a51f78075/Images/Documentation/manager%20detail%20edit.png)
3. Check `Use Custom Trigger`. ![check use custom trigger](https://cdn.document360.io/f977eec0-500f-40a3-b663-724a51f78075/Images/Documentation/check%20use%20custom%20trigger.png)
4. Press **Save**. ![use custom trigger is checked](https://cdn.document360.io/f977eec0-500f-40a3-b663-724a51f78075/Images/Documentation/use%20custom%20trigger%20is%20checked.png)
5. Create your own Apex Trigger using the code snippet below as an example.

**Sample Custom PCIFY Apex Trigger**

```
trigger InboundEmailMessageTrigger on EmailMessage (before insert) {       List incomingEms = new List();        // check if Detection is turned on for Email Message    if (pcify.Manager.getManager('EmailMessage').pcifyisActivec) {        // collect incoming emails        for (EmailMessage em : Trigger.new) {            if (em.Incoming) {                incomingEms.add(em);            }         }              // process only incoming emails with PCIFY        pcify.Processor.maskCreditCards(            incomingEms,            pcify.Manager.getMaskFields('EmailMessage'),            'EmailMessage'        );    }}
```
