Prerequisites for getting started with API Gateway
To use API Gateway and other Amazon services, you need an Amazon account. If you don't have an account, visit www.amazonaws.cn
As a best practice, you should also create an Amazon Identity and Access Management (IAM) user with administrator permissions and use that for all work that does not require root credentials. Create a password for console access, and access keys to use command line tools. See Creating your first IAM admin user and group in the IAM User Guide for instructions.
