Written by
Updated at December 17, 2024

Retrieves the list of trails in the specified folder.

gRPC request

rpc List (ListTrailsRequest) returns (ListTrailsResponse)

ListTrailsRequest

{
  "folder_id": "string",
  "page_size": "int64",
  "page_token": "string",
  "filter": "string",
  "order_by": "string"
}

Field

Description

folder_id

string

Required field. ID of the folder to list trails in.

page_size

int64

The maximum number of results per page to return. If the number of available
results is larger than page_size, the service returns a ListTrailsResponse.next_page_token
that can be used to get the next page of results in subsequent list requests.
Default value: 100.

page_token

string

Page token. To get the next page of results, set page_token to the
[ListTrailsRequest.next_page_token] returned by a previous list request.

filter

string

A filter expression that filters subscription locks listed in the response.

The expression must specify:

  1. The field name. Currently you can use filtering on [Trail.name, Trail.created_at] fields.
  2. An operator. Can be either = or != for single values, IN or NOT IN for lists of values.
  3. The value. Must be in double quotes "". Must be 3-63 characters long and match the regular expression ^[a-z][-a-z0-9]{1,61}[a-z0-9].
    Example of a filter: name="my-name".

order_by

string

By which column the listing should be ordered and in which direction.
format is " desc|acs"
