Request Syntax

   "Filters": [ 
      { 
         "Condition": "string",
         "Name": "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 services for.

If you specify more than one filter, an operation must match all filters to be returned by ListServices.

Type: Array of ServiceFilter objects

Required: No

MaxResults

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

Type: Integer

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

Required: No

NextToken

For the first ListServices request, omit this value.

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

Note

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

Type: String

Length Constraints: Maximum length of 4096.

Required: No
