Example
In this example, the request updates the Infrastructure - Linux auto-tag from the GET request example.
The initial configuration is the following:
The request adds an extra condition to the existing rule for the prod tag value, additionally requiring host group name to contain production.
It also adds a new rule that assigns the preProd tag value for Linux hosts with names beginning with PreProd.
The API token is passed in the Authorization header.
The request body is lengthy, so it is truncated in the Curl section. See the Request body section for the full body. You can download or copy the example request body to try it out on your own.
