# AWS::IoTFleetWise::DecoderManifest
<a name="aws-resource-iotfleetwise-decodermanifest"></a>

Creates the decoder manifest associated with a model manifest. To create a decoder manifest, the following must be true:
+ Every signal decoder has a unique name.
+ Each signal decoder is associated with a network interface.
+ Each network interface has a unique ID.
+ The signal decoders are specified in the model manifest.

For more information, see [Decoder manifests](https://docs.aws.amazon.com/iot-fleetwise/latest/developerguide/decoder-manifests.html) in the *AWS IoT FleetWise Developer Guide*.

**Important**  
Access to certain AWS IoT FleetWise features is currently gated. For more information, see [AWS Region and feature availability ](https://docs.aws.amazon.com/iot-fleetwise/latest/developerguide/fleetwise-regions.html) in the *AWS IoT FleetWise Developer Guide*.
