Did you return the validation token while creating the subscription? You have to return the validation token within 3 seconds. Otherwise, you would receive that error message. See the dev guide for sample code of how to return a validation token.

I already read the dev Guide. But my question is where do I get the validation token? because in the dev guide there is no parameter passed as a validation token. There is only Url, events, delivery mode, transport, and address. Please help me with that.

Check the Getting Started code example. Here is the highlighted part showing how to just return the validation token in the header.

if (req.headers.hasOwnProperty("validation-token")) {
        res.setHeader('Content-type', 'application/json');
        res.setHeader('Validation-Token', req.headers['validation-token']);
        res.statusCode = 200;
        res.end();
      }
