Syntax

To declare this entity in your CloudFormation template, use the following syntax:

JSON

  "FirstByteTimeoutMilliseconds" : Integer,
  "Model" : String,
  "TargetName" : String,
  "TriggerOn" : FallbackTriggers
}

Properties

FirstByteTimeoutMilliseconds

The maximum time, in milliseconds, from sending the request to this target until the first byte of the response body arrives. This setting isn't inherited from the route. If you don't specify a value, no timeout is enforced.

Required: No

Type: Integer

Minimum: 50

Maximum: 900000

Update requires: No interruption

Model

The model ID to send to this fallback target. If you don't specify a model, the gateway sends the model from the original request.

Minimum: 1

TriggerOn

The status codes and errors from this target that cause the gateway to send the request to the next fallback target. This setting isn't inherited from the route. If you omit it, the gateway uses the default triggers: 5XX status codes and the CONNECTION_ERROR, FIRST_BYTE_TIMEOUT, and UNROUTABLE errors.

Required: No

Type: FallbackTriggers
