5. Developer Resources

It is recommended to use API 3.0 Explorer. This tool provides various capabilities such as online debugging, signature verification, SDK code generation and quick API retrieval that significantly reduce the difficulty of using cloud APIs.

Cloud API 3.0 comes with a set of complementary development tools that make it easier to call the API.
