## Request Syntax
```
{
"assessmentRunArn": "string",
"filter": {
"agentHealthCodes": [ "string" ],
"agentHealths": [ "string" ]
},
"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.
** [assessmentRunArn](#API_ListAssessmentRunAgents_RequestSyntax) **
The ARN that specifies the assessment run whose agents you want to list.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 300.
Required: Yes
** [filter](#API_ListAssessmentRunAgents_RequestSyntax) **
You can use this parameter to specify a subset of data to be included in the action's response.
For a record to match a filter, all specified filter attributes must match. When multiple values are specified for a filter attribute, any of the values can match.
Type: [AgentFilter](API_AgentFilter.md) object
Required: No
** [maxResults](#API_ListAssessmentRunAgents_RequestSyntax) **
You can use this parameter to indicate the maximum number of items that you want in the response. The default value is 10. The maximum value is 500.
Type: Integer
Required: No
** [nextToken](#API_ListAssessmentRunAgents_RequestSyntax) **
You can use this parameter when paginating results. Set the value of this parameter to null on your first call to the **ListAssessmentRunAgents** action. Subsequent calls to the action fill **nextToken** in the request with the value of **NextToken** from the previous response to continue listing data.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 300.
Required: No
