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

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  
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

  1. RequestBody formBody = new FormBody.Builder().add("JSONString", invoiceRequest.toString()).build(); 

  2. Request request = new Request.Builder().url("https://invoice.zoho.com/api/v3/invoices").post(formBody)

  3. .addHeader("Authorization", "Zoho-authtoken " + zohoEntities.getInvoiceAuthToken())

  4. .addHeader("X-com-zoho-invoice-organizationid", zohoEntities.getOrganizationId())

  5. .addHeader( "Content-Type" , "application/x-www-form-urlencoded;charset=UTF-8" )
    .addHeader( "Cache-Control" , "no-cache" ).build();

  6. 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,
