Tooling API Inactivate Apex Trigger

Question

I am trying to inactive Apex Trigger using tooling API. I don't see any errors, I am getting "Success" message, but Trigger is not getting updated with inactive flag.

String json= '{ "MetadataContainerId":"1dcS0000000fGp7IAE", "ContentEntityId": "01qS0000000YCKZIA4", "Metadata": { "status": "Inactive"} }';
Httprequest req =new HttpRequest();
req.setEndpoint(URL.getSalesforceBaseUrl().toExternalForm()+'/services/data/v43.0/tooling/sobjects/ApexTriggerMember/');
req.setHeader('Content-Type','application/json');
req.setHeader('Authorization','OAuth ' + UserInfo.getSessionId());
req.setMethod('POST');
req.setBody(json);
Http httpReq =new Http();
HttpResponse res = httpReq.send(req);
System.debug(res.getBody());

Your request to update the ApexTriggerMember of this MetadataContainer succeeds, but that doesn't actually perform a deployment - it stages it in the container. The ApexTrigger Tooling API object itself does not support CRUD operations in an active org.

From the Tooling API documentation,

Use a MetadataContainer as a package for your tool’s workspace. As a user works in the tool, update the ApexClassMember, ApexTriggerMember, ApexPageMember and ApexComponentMember objects in the MetadataContainer and use a ContainerAsyncRequest object to save and deploy changes to the current organization.

You need to use a ContainerAsyncRequest to request a deployment of your container (by supplying its Id in the MetadataContainerId field).
