node.js - Resolving a setTimeout inside API endpoint

Answer

I need to add a delay to an API call so I'm using setTimeout. After 2 seconds on success, I need to return res.status(200).json(response).

  exports.someEndpoint = function(req, res) {
    return request.post({
      url: //etc

    })
    .then(function(response) {
      return new Promise(function(resolve, reject) {
        setTimeout(function() {
          // is this right?
          resolve(
            res.status(200).json(response);
          );
        }, 2000);
      });

    });
  };

My question is: do I need to call resolve inside the setTimeout? Or can I just completely omit it?
