Request Syntax


{
   "Filters": [ 
      { 
         "Condition": "string",
         "Name": "string",
         "Values": [ "string" ]
      }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Filters

A complex type that contains specifications for the namespaces that you want to list.

If you specify more than one filter, a namespace must match all filters to be returned by ListNamespaces.

Type: Array of NamespaceFilter objects

Required: No

MaxResults

The maximum number of namespaces that you want Amazon Cloud Map to return in the response to a ListNamespaces request. If you don't specify a value for MaxResults, Amazon Cloud Map returns up to 100 namespaces.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 100.

Required: No

NextToken

For the first ListNamespaces request, omit this value.

If the response contains NextToken, submit another ListNamespaces request to get the next group of results. Specify the value of NextToken from the previous response in the next request.

Note

Amazon Cloud Map gets MaxResults namespaces and then filters them based on the specified criteria. It's possible that no namespaces in the first MaxResults namespaces matched the specified criteria but that subsequent groups of MaxResults namespaces do contain namespaces that match the criteria.

Type: String

Length Constraints: Maximum length of 4096.

Required: No
