# UpdateGatewayCapabilityConfiguration
<a name="API_UpdateGatewayCapabilityConfiguration"></a>

Updates a gateway capability configuration or defines a new capability configuration. Each gateway capability defines data sources for a gateway.

Important workflow notes:

Each gateway capability defines data sources for a gateway. This is the namespace of the gateway capability.

. The namespace follows the format `service:capability:version`, where:
+  `service` - The service providing the capability, or `iotsitewise`.
+  `capability` - The specific capability type. Options include: `opcuacollector` for the OPC UA data source collector, or `publisher` for data publisher capability.
+  `version` - The version number of the capability. Option include `2` for Classic streams, V2 gateways, and `3` for MQTT-enabled, V3 gateways.

After updating a capability configuration, the sync status becomes `OUT_OF_SYNC` until the gateway processes the configuration.Use `DescribeGatewayCapabilityConfiguration` to check the sync status and verify the configuration was applied.

A gateway can have multiple capability configurations with different namespaces.

## Request Syntax
<a name="API_UpdateGatewayCapabilityConfiguration_RequestSyntax"></a>

```
POST /20200301/gateways/gatewayId/capability HTTP/1.1
Content-type: application/json

{
   "capabilityConfiguration": "string",
   "capabilityNamespace": "string"
}
```

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

The request uses the following URI parameters.

 ** [gatewayId](#API_UpdateGatewayCapabilityConfiguration_RequestSyntax) **   <a name="iotsitewise-UpdateGatewayCapabilityConfiguration-request-uri-gatewayId"></a>
The ID of the gateway to be updated.  
Length Constraints: Fixed length of 36.  
Pattern: `^(?!00000000-0000-0000-0000-000000000000)[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$`   
Required: Yes

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

The request accepts the following data in JSON format.

 ** [capabilityConfiguration](#API_UpdateGatewayCapabilityConfiguration_RequestSyntax) **   <a name="iotsitewise-UpdateGatewayCapabilityConfiguration-request-capabilityConfiguration"></a>
The JSON document that defines the configuration for the gateway capability. For more information, see [Configuring data sources (CLI)](https://docs.aws.amazon.com/iot-sitewise/latest/userguide/configure-sources.html#configure-source-cli) in the * AWS IoT SiteWise User Guide*.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 10000000.  
Required: Yes

 ** [capabilityNamespace](#API_UpdateGatewayCapabilityConfiguration_RequestSyntax) **   <a name="iotsitewise-UpdateGatewayCapabilityConfiguration-request-capabilityNamespace"></a>
The namespace of the gateway capability configuration to be updated. For example, if you configure OPC UA sources for an MQTT-enabled gateway, your OPC-UA capability configuration has the namespace `iotsitewise:opcuacollector:3`.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 512.  
Pattern: `^[a-zA-Z]+:[a-zA-Z]+:[0-9]+$`   
Required: Yes

## Response Syntax
<a name="API_UpdateGatewayCapabilityConfiguration_ResponseSyntax"></a>

```
HTTP/1.1 201
Content-type: application/json

{
   "capabilityNamespace": "string",
   "capabilitySyncStatus": "string"
}
```

## Response Elements
<a name="API_UpdateGatewayCapabilityConfiguration_ResponseElements"></a>

If the action is successful, the service sends back an HTTP 201 response.

The following data is returned in JSON format by the service.

 ** [capabilityNamespace](#API_UpdateGatewayCapabilityConfiguration_ResponseSyntax) **   <a name="iotsitewise-UpdateGatewayCapabilityConfiguration-response-capabilityNamespace"></a>
The namespace of the gateway capability.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 512.  
Pattern: `^[a-zA-Z]+:[a-zA-Z]+:[0-9]+$` 

 ** [capabilitySyncStatus](#API_UpdateGatewayCapabilityConfiguration_ResponseSyntax) **   <a name="iotsitewise-UpdateGatewayCapabilityConfiguration-response-capabilitySyncStatus"></a>
The synchronization status of the gateway capability configuration. The sync status can be one of the following:  
+  `IN_SYNC` - The gateway is running with the latest configuration.
+  `OUT_OF_SYNC` - The gateway hasn't received the latest configuration.
+  `SYNC_FAILED` - The gateway rejected the latest configuration.
+  `UNKNOWN` - The gateway hasn't reported its sync status.
+  `NOT_APPLICABLE` - The gateway doesn't support this capability. This is most common when integrating partner data sources, because the data integration is handled externally by the partner.
After you update a capability configuration, its sync status is `OUT_OF_SYNC` until the gateway receives and applies or rejects the updated configuration.  
Type: String  
Valid Values: `IN_SYNC | OUT_OF_SYNC | SYNC_FAILED | UNKNOWN | NOT_APPLICABLE` 

## Errors
