Creates an activation code. This activation code is used to register servers that are not provided by Alibaba Cloud as Alibaba Cloud managed instances.


After you use an activation code to register a server that is not provided by Alibaba Cloud as an Alibaba Cloud managed instance, you can use a variety of online services provided by Alibaba Cloud, such as Cloud Assistant, Operation Orchestration Service (OOS), and Apsara Devops in the managed instance.

If a server is not provided by Alibaba Cloud, it can be registered as an Alibaba Cloud managed instance only when the server can access the Internet and runs an operating system of one of the following versions:

  • Alibaba Cloud Linux 2
  • CentOS 6, CentOS 7, CentOS 8, and later
  • Debian 8, Debian 9, Debian 10, and later
  • Ubuntu 12, Ubuntu 14, Ubuntu 16, Ubuntu 18, and later
  • CoreOS
  • OpenSUSE
  • RedHat 5, RedHat 6, RedHat 7, and later
  • SUSE Linux Enterprise Server (SLES) 11, SLES 12, SLES 15, and later
  • Windows Server 2012, Windows Server 2016, Windows Server 2019, and later


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
