Zip API US now allows you to perform client-side calls. In order to make client-side calls, do the following:
- Generate a js key from your account by going to your dashboard.
- Add the domain(s) from which you will be performing your client-side calls.
Your js key is only used for client-side calls while your primary api key is designed for server-side calls. If you do not add your domain(s), your calls will receive a cross-origin request (CORS) error.
