Hi there @yigiteren,

I believe that one way to do so is to add an additional middleware and only allow requests from your specific IP.

You could use something like this:

function restrictAccess(req, res, next) {
      if (req.headers['origin'] !== '') {
      } else {

However, this could be manipulated as people could add additional headers to their requests if they wanted to, so a better approach would be to use a JWT token for authentication. To do that you could take a look at these two tutorials here:

Hope that this helps. Regards, Bobby
