How to Delete All Debug Apex logs in Apex? [duplicate]

Question

I'm trying to delete the complete Apex debug logs but getting DML operation Delete not allowed on List<ApexLog>.

Code:

List <Apexlog> loglist = [Select Id from Apexlog];
delete loglist;

Please provide an idea to delete complete debug logs in code.

Answer 1

You cannot delete the debug logs natively in Apex code. But you can use Rest DELETE endpoint to delete debug logs.

I have created a utility code to delete debug logs that way, you can refer it.

The only limitation is

1. It can delete only 100 in 1 iteration(You can use composite API to bulkify it)

2. It creates a new debug log after execution

   List <Apexlog> loglist = [Select Id from Apexlog limit 100];
   for(Apexlog al: loglist){
       Http h = new Http();
       HttpRequest req = new HttpRequest();
       req.setEndpoint(Url.getOrgDomainUrl().toExternalForm()
       + '/services/data/v44.0/sobjects/Apexlog/'+al.Id);
       req.setMethod('DELETE');
       req.setHeader('Authorization', 'Bearer ' + UserInfo.getSessionId());
       HttpResponse res = h.send(req);
       System.debug(res.getStatusCode());
   }
   
   System.debug('loglist'+loglist);
   

If you are calling this method from lightning component, your Session ID wont be api enabled. Thus you have to use named credentials .

As far as I can tell, the documentation is mistaken in showing that ApexLog can be deleted from Apex DML.

The object is deletable from the Tooling API, however. You can tackle this in two ways:

1. You can actually call out to the Tooling API from your Apex code to perform a delete operation on the object. You would make a DELETE method callout to the REST endpoint

   /services/data/v43.0/tooling/sobjects/ApexLog/YOUR_LOG_ID

2. You can do it directly from the Developer Console, without writing a line of code. Simply write SELECT Id FROM ApexLog in the Query Editor, check "Use Tooling API", and execute the query. Then, select rows in the results display, and click the Delete Rows button to remove them.
