Need to integrate the WorldPay in my app

I need to integrate the WorldPay as a Payment Gateway into my android application. I am referring the following link to integrate the Worldpay into my application.

https://developer.worldpay.com/jsonapi/docs/android

I have implemented all the scenarios as per mentioned in the documentation.

But when I am initializing the WorldPay it will ask for the "YOUR_CLIENT_KEY", Soo, I logged into the virtual terminal from the Worldpay sandbox account but there but from the key management I am only getting the Secure key and public key.

Soo can anyone help me from where I can generate the "CLIENT_KEY" for the application?

Also, another question is how can I generate the Token for the particular user, I am only getting the error on the "onResponseError" after calling the worldpay.createTokenAsyncTask.

Please help me out how do I integrate the proper integration, there is no other documentation is available there to get out of this.

For this, we can't generate the client key for the test account on the WorldPay. You have to create your request for create yopur account on http://online.worldpay.com . Once you have your WorldPay account you will get your all account API keys from the following link: settings/keys

Here, you can get Service key and Client key for both test and live account.

You will get your token in the following method for the custom form:

createTokenAsyncTask = worldpay.createTokenAsyncTask(this, card, new WorldPayResponse() {
        @Override
        public void onSuccess(ResponseCard responseCard) {
            Log.e("***+++","Token is : "+responseCard);
        }

        @Override
        public void onResponseError(ResponseError responseError) {
        }

        @Override
        public void onError(WorldPayError worldPayError) {
        }
    });
