# ListCapabilities


Lists the capabilities associated with your AWS account for your current or specified region. A trading capability contains the information required to transform incoming EDI documents into JSON or XML outputs.

## Request Syntax


```
{
   "maxResults": number,
   "nextToken": "string"
}
```

## Request Parameters


For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [maxResults](#API_ListCapabilities_RequestSyntax) **   <a name="b2bi-ListCapabilities-request-maxResults"></a>
Specifies the maximum number of capabilities to return.  
Type: Integer  
Valid Range: Minimum value of 1. Maximum value of 100.  
Required: No

 ** [nextToken](#API_ListCapabilities_RequestSyntax) **   <a name="b2bi-ListCapabilities-request-nextToken"></a>
When additional results are obtained from the command, a `NextToken` parameter is returned in the output. You can then pass the `NextToken` parameter in a subsequent command to continue listing additional resources.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 2048.  
Required: No

## Response Syntax


```
{
   "capabilities": [ 
      { 
         "capabilityId": "string",
         "createdAt": "string",
         "modifiedAt": "string",
         "name": "string",
         "type": "string"
      }
   ],
   "nextToken": "string"
}
```

## Response Elements


If the action is successful, the service sends back an HTTP 200 response.

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

 ** [capabilities](#API_ListCapabilities_ResponseSyntax) **   <a name="b2bi-ListCapabilities-response-capabilities"></a>
Returns one or more capabilities associated with this partnership.  
Type: Array of [CapabilitySummary](API_CapabilitySummary.md) objects

 ** [nextToken](#API_ListCapabilities_ResponseSyntax) **   <a name="b2bi-ListCapabilities-response-nextToken"></a>
When additional results are obtained from the command, a `NextToken` parameter is returned in the output. You can then pass the `NextToken` parameter in a subsequent command to continue listing additional resources.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 2048.

## Errors


For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).

 ** AccessDeniedException **   
You do not have sufficient access to perform this action.  
HTTP Status Code: 400

 ** InternalServerException **   
This exception is thrown when an error occurs in the AWS B2B Data Interchange service.    
 ** retryAfterSeconds **   
The server attempts to retry a failed command.
HTTP Status Code: 500

 ** ThrottlingException **   
The request was denied due to throttling: the data speed and rendering may be limited depending on various parameters and conditions.    
 ** retryAfterSeconds **   
The server attempts to retry a command that was throttled.
HTTP Status Code: 400

 ** ValidationException **   
When you use Transformer APIs, `TestConversion`, or `TestParsing`, the service throws a validation exception if a rule is configured incorrectly. For example, a validation exception occurs when:  
+ A rule references an element that doesn't exist in the selected transaction set
+ An element length rule specifies a minimum length less than 0
If your custom validation rules are configured correctly but the EDI validation fails due to those rules, this is expected behavior and doesn't result in a `ValidationException`.
For all other API operations, a validation exception occurs when a Trading Partner object can't be validated against a request from another object. This can happen during:  
+ Standard EDI validation
+ Custom validation rule evaluation, such as when:
  + Element lengths don't meet specified constraints
  + Code list validations contain invalid codes
  + Required elements are missing based on your element requirement rules
HTTP Status Code: 400

## Examples


### Example


The following example lists the capabilities for your account and in your region. Note that in this example, there is only one capability listed: however, this call would return up to 50 capabilities.

#### Sample Request


```
{
    "maxResults": 50,
    "nextToken": "foo"
}
```

#### Sample Response


```
{
    "capabilities": [
        {
            "capabilityId": "ca-1111aaaa2222bbbb3",
            "createdAt": "2023-11-01T21:51:05.504Z",
            "modifiedAt": "2023-11-01T21:51:05.504Z",
            "name": "b2biexample",
            "type": "edi"
        }
    ],
    "nextToken": "foo"
}
```
