Parameters

The following table describes the parameters in the metadata of an event target.

Parameter Type Description
resourceKey String The key of the resource that is used in event transformation.
resourceName String The name of the resource that is used in event transformation.
forms String The transformation method. The following transformation methods are supported:
  • ORIGINAL: complete event. You do not need to specify the value or template field. EventBridge routes the complete data structure of an event in the CloudEvents format to an event target without transformation. For more information, see the "Complete event" section in Event transformation.
  • JSONPATH: partial event. You need to specify only the value field and do not need to specify the template field. EventBridge extracts fields from an event in the CloudEvents format by using JSONPath and routes the specified part of the event to an event target. For more information, see the "Partial event" section in Event transformation.
    Sample value of the value field: 
    $.data.name
  • CONSTANT: constant. You need to specify only the value field and do not need to specify the template field. EventBridge routes only constants specified by the value field to an event target regardless of event context. For more information, see the "Constant" section in Event transformation.
    Sample value of the value field: 
    "test1"
  • TEMPLATE: template. You must specify the value and template fields. EventBridge extracts fields from an event in the CloudEvents format by using JSONPath, stores the field values in the value field, and then routes the event in the format that is specified by the template field to an event target. For more information, see the "Template" section in Event transformation.
    Sample value of the value field: 
    {
    "name":"$.data.name",
    "constant":"Please deal with it timely."
}
    Sample value of the template field: 
    The instance is broken, which name is ${name}, ${constant}
