Getting scope error(23:Invalid Scope Passed) while creating invoice using zoho invoice api.

I am new to zoho invoice api, I want to create invoice for one of my application and I choose to use invoice api. I red the documentation.

I am facing scope error while creating invoice.

I am using url

https://accounts.zoho.com/apiauthtoken/nb/create

   and parameters as

   ?SCOPE=ZohoInvoice/invoiceapi&EMAIL_ID=[ZohoID/EmailID]&PASSWORD=[Password]

to generate

authtoken from my java application api.

and following is my service to create invoice

RequestBody formBody = new FormBody.Builder().add("JSONString", invoiceRequest.toString()).build();
Request request = new Request.Builder().url("https://invoice.zoho.com/api/v3/invoices").post(formBody)
.addHeader("Authorization", "Zoho-authtoken " + zohoEntities.getInvoiceAuthToken())
.addHeader("X-com-zoho-invoice-organizationid", zohoEntities.getOrganizationId())
.addHeader( "Content-Type" , "application/x-www-form-urlencoded;charset=UTF-8" )

.addHeader( "Cache-Control" , "no-cache" ).build();
response = client.newCall(request).execute();

I have a doubt that scope I used (

ZohoInvoice/invoiceapi)

will support the creation invoice or we need any other scope.

In documentation mentioned authentication going to be deprecated.

    Do i need to use 
    
    https://accounts.zoho.com/oauth/v2/auth?
and scope 
    
    ZohoInvoice.invoices.CREATE,ZohoInvoice.invoices.READ,ZohoInvoice.invoices.UPDATE,ZohoInvoice.invoices.DELETE

to get access token and refresh tokens.

Thanks,
