What does the API key do?
After subscribing to a ShipsGo account, you are going to have an API Key. You can consider this key as a communication code between your company website and ShipsGo. Thanks to this key, when you or your customers request a container tracking we are able to recognize that this request comes from your website. Then, our system sends a notification e-mail to you/your customers with your logo - i.e., on behalf of you. Besides, we use this code to manage your API credit as well.
