<a name="API_ListOperations"></a>

Lists operations that match the criteria that you specify.

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

```
{
   "Filters": [ 
      { 
         "Condition": "string",
         "Name": "string",
         "Values": [ "string" ]
      }
   ],
   "MaxResults": number,
   "NextToken": "string"
}
```

## Request Parameters
<a name="API_ListOperations_RequestParameters"></a>

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.

 ** [Filters](#API_ListOperations_RequestSyntax) **   <a name="cloudmap-ListOperations-request-Filters"></a>
A complex type that contains specifications for the operations that you want to list, for example, operations that you started between a specified start date and end date.  
If you specify more than one filter, an operation must match all filters to be returned by `ListOperations`.  
Type: Array of [OperationFilter](API_OperationFilter.md) objects  
Required: No

 ** [MaxResults](#API_ListOperations_RequestSyntax) **   <a name="cloudmap-ListOperations-request-MaxResults"></a>
The maximum number of items that you want AWS Cloud Map to return in the response to a `ListOperations` request. If you don't specify a value for `MaxResults`, AWS Cloud Map returns up to 100 operations.  
Type: Integer  
Valid Range: Minimum value of 1. Maximum value of 100.  
Required: No

 ** [NextToken](#API_ListOperations_RequestSyntax) **   <a name="cloudmap-ListOperations-request-NextToken"></a>
For the first `ListOperations` request, omit this value.  
If the response contains `NextToken`, submit another `ListOperations` request to get the next group of results. Specify the value of `NextToken` from the previous response in the next request.  
 AWS Cloud Map gets `MaxResults` operations and then filters them based on the specified criteria. It's possible that no operations in the first `MaxResults` operations matched the specified criteria but that subsequent groups of `MaxResults` operations do contain operations that match the criteria.
Type: String  
Length Constraints: Maximum length of 4096.  
Required: No

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

{
   "NextToken": "string",
   "Operations": [ 
      { 
         "Id": "string",
         "Status": "string"
      }
   ]
}
```

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

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

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

 ** [NextToken](#API_ListOperations_ResponseSyntax) **   <a name="cloudmap-ListOperations-response-NextToken"></a>
If the response contains `NextToken`, submit another `ListOperations` request to get the next group of results. Specify the value of `NextToken` from the previous response in the next request.  
 AWS Cloud Map gets `MaxResults` operations and then filters them based on the specified criteria. It's possible that no operations in the first `MaxResults` operations matched the specified criteria but that subsequent groups of `MaxResults` operations do contain operations that match the criteria.
Type: String  
Length Constraints: Maximum length of 4096.

 ** [Operations](#API_ListOperations_ResponseSyntax) **   <a name="cloudmap-ListOperations-response-Operations"></a>
Summary information about the operations that match the specified criteria.  
Type: Array of [OperationSummary](API_OperationSummary.md) objects

## Errors
<a name="API_ListOperations_Errors"></a>

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

One or more specified values aren't valid. For example, a required value might be missing, a numeric value might be outside the allowed range, or a string value might exceed length constraints.
