    Queries resource quotas. For example, you can call the DescribeLimitation operation to query the maximum numbers of scheduled tasks that you can create in a scaling group, load balancers that you can attach to a scaling group, instances that you can add to a scaling group, and scaling configurations that you can create in a scaling group.

    Debugging

    You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

    Authorization information
