HTTP/1.1
URI Request Parameters
The request uses the following URI parameters.
- limit
-
The maximum number of results returned by
ListVirtualNodes
in paginated output. When you use this parameter,ListVirtualNodes
returns onlylimit
results in a single page along with anextToken
response element. You can see the remaining results of the initial request by sending anotherListVirtualNodes
request with the returnednextToken
value. This value can be between 1 and 100. If you don't use this parameter,ListVirtualNodes
returns up to 100 results and anextToken
value if applicable.Valid Range: Minimum value of 1. Maximum value of 100.
- meshName
-
The name of the service mesh to list virtual nodes in.
Length Constraints: Minimum length of 1. Maximum length of 255.
Required: Yes
- meshOwner
-
The AWS IAM account ID of the service mesh owner. If the account ID is not your own, then it's the ID of the account that shared the mesh with your account. For more information about mesh sharing, see Working with shared meshes.
Length Constraints: Fixed length of 12.
- nextToken
-
The
nextToken
value returned from a previous paginatedListVirtualNodes
request wherelimit
was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned thenextToken
value.
Request Body
The request does not have a request body.

, you can use this value to retrieve the next page of results. This value isnull
when there are no more results to return.Type: String

-
The list of existing virtual nodes for the specified service mesh.
Type: Array of VirtualNodeRef objects
