## URI Request Parameters
<a name="API_CreateFuotaTask_RequestParameters"></a>

The request does not use any URI parameters.

## Request Body
<a name="API_CreateFuotaTask_RequestBody"></a>

The request accepts the following data in JSON format.

 ** [ClientRequestToken](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-ClientRequestToken"></a>
Each resource must have a unique client request token. The client token is used to implement idempotency. It ensures that the request completes no more than one time. If you retry a request with the same token and the same parameters, the request will complete successfully. However, if you try to create a new resource using the same token but different parameters, an HTTP 409 conflict occurs. If you omit this value, AWS SDKs will automatically generate a unique client request. For more information about idempotency, see [Ensuring idempotency in Amazon EC2 API requests](https://docs.aws.amazon.com/ec2/latest/devguide/ec2-api-idempotency.html).  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 64.  
Pattern: `^[a-zA-Z0-9-_]+$`   
Required: No

 ** [Description](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-Description"></a>
The description of the new resource.  
Type: String  
Length Constraints: Maximum length of 2048.  
Required: No

 ** [Descriptor](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-Descriptor"></a>
The descriptor is the metadata about the file that is transferred to the device using FUOTA, such as the software version. It is a binary field encoded in base64.  
Type: String  
Length Constraints: Maximum length of 332.  
Pattern: `^(?:[A-Za-z0-9+/]{4})*(?:[A-Za-z0-9+/]{2}==|[A-Za-z0-9+/]{3}=)?$`   
Required: No

 ** [FirmwareUpdateImage](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-FirmwareUpdateImage"></a>
The S3 URI points to a firmware update image that is to be used with a FUOTA task.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 4096.  
Required: Yes

 ** [FirmwareUpdateRole](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-FirmwareUpdateRole"></a>
The firmware update role that is to be used with a FUOTA task.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 2048.  
Required: Yes

 ** [FragmentIntervalMS](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-FragmentIntervalMS"></a>
The interval for sending fragments in milliseconds, rounded to the nearest second.  
This interval only determines the timing for when the Cloud sends down the fragments to yor device. There can be a delay for when your device will receive these fragments. This delay depends on the device's class and the communication delay with the cloud.
Type: Integer  
Valid Range: Minimum value of 1.  
Required: No

 ** [FragmentSizeBytes](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-FragmentSizeBytes"></a>
The size of each fragment in bytes. This parameter is supported only for FUOTA tasks with multicast groups.  
Type: Integer  
Valid Range: Minimum value of 1.  
Required: No

 ** [LoRaWAN](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-LoRaWAN"></a>
The LoRaWAN information used with a FUOTA task.  
Type: [LoRaWANFuotaTask](API_LoRaWANFuotaTask.md) object  
Required: No

 ** [Name](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-Name"></a>
The name of a FUOTA task.  
Type: String  
Length Constraints: Maximum length of 256.  
Required: No

 ** [RedundancyPercent](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-RedundancyPercent"></a>
The percentage of the added fragments that are redundant. For example, if the size of the firmware image file is 100 bytes and the fragment size is 10 bytes, with `RedundancyPercent` set to 50(%), the final number of encoded fragments is (100 / 10) \$1 (100 / 10 \$1 50%) = 15.  
Type: Integer  
Valid Range: Minimum value of 0. Maximum value of 100.  
Required: No

 ** [Tags](#API_CreateFuotaTask_RequestSyntax) **   <a name="iotwireless-CreateFuotaTask-request-Tags"></a>
The tag to attach to the specified resource. Tags are metadata that you can use to manage a resource.  
Type: Array of [Tag](API_Tag.md) objects  
Array Members: Minimum number of 0 items. Maximum number of 200 items.  
Required: No
