To activate the API Gateway service, you need to use resources in other Tencent Cloud services. Therefore, you must authorize API Gateway to access your Tencent Cloud resources.
After you register a Tencent Cloud account, the system will create a root account for you by default, which is used to quickly access Tencent Cloud resources.
When you log in to the API Gateway console with the root account for the first time, you need to click Activate Now on the console overview page to activate the API Gateway service.
Since API Gateway hasn't been granted a service role, it cannot access the resources of other Tencent Cloud services. You need to click Authorize to enter the CAM console for authorization.
Click Agree to authorize the API Gateway service to access your resources.
For more information on how to use API Gateway with a sub-account or collaborator, see Permission Management.
