Getting invalid oauthscope when trying to create a new contact

Getting invalid oauthscope when trying to create a new contact

When I go to use the API to create a new Contact within the CRM, I'm getting:

{"code":2945,"description":"This is an invalid oauthscope. Please regenerate the oauthtoken corresponding to the API with proper oauthscope."}

I am using the following scope:

ZohoCRM.modules.contacts.CREATE

Also, what scope would I use if I wanted to create a new lead instead?

Thanks for the help.
