Querying Lists

Supported Operations

Operation	URL Format	Required Parameters	Description
`query`	`/api/list/version/3/do/query?...`	`user_key, api_key`	Returns the lists matching the specified criteria parameters. See the Using Lists section for a complete description of the list XML Response Format. Also see List in Object Field References

Supported Search Criteria

Search criteria may be used together in any combination and/or order unless otherwise specified. Unless output=mobile is specified, 200 lists will be returned with each query request. This limit is not enforced for responses formatted for mobile devices.

Parameter	Datatype	Options	Description
`created_after`	`string`	`today, yesterday, last_7_days, this_month, last_month, <custom_time>`	Searches for lists that were created after the specified time. If a `<custom_time>` is used, ensure that the specified date is formatted using GNU Date Input Syntax
`created_before`	`string`	`today, yesterday, last_7_days, this_month, last_month, <custom_time>`	Searches for lists that were created before the specified time. If a `<custom_time>` is used, ensure that the specified date is formatted using GNU Date Input Syntax
`id_greater_than`	`integer`	`<any_positive_integer>`	Searches for lists with IDs greater than the specified integer
`id_less_than`	`integer`	`<any_positive_integer>`	Searches for lists with IDs less than the specified integer
`name`	`string`	`<any string>`	Searches for lists a name exactly matching the given name
`updated_before`	`string`	`today, yesterday, last_7_days, this_month, last_month, <custom_time>`	Searches for lists that were updated before the specified time. If a `<custom_time>` is used, ensure that the specified date is formatted using GNU Date Input Syntax
`updated_after`	`string`	`today, yesterday, last_7_days, this_month, last_month, <custom_time>`	Searches for lists that were updated after the specified time. If a `<custom_time>` is used, ensure that the specified date is formatted using GNU Date Input Syntax

Manipulating the Result Set

Since query result sets are limited to 200 results each, the results returned may not include all the lists matched by the query. To retrieve the remaining results, the following criteria can be used to navigate through the result set.

Parameter	Datatype	Options	Description
`limit`	`integer`	`<any_positive_integer>`	Specifies the number of results to be returned. Default value: `200`. *Note:* This number cannot be larger than 200. If a number larger than 200 is specified, 200 will be used
`offset`	`integer`	`<any_positive_integer>`	Specifies the first matching list (according to the specified sorting order) to be returned in the `query` response. The first `offset` matching lists will be omitted from the response. Default value: `0`. *Example:* Specifying `offset=10` will return the results starting with the 11th list matched by the provided criteria
`sort_by`	`string`	`created_at, id`	Specifies the field that should be used to sort the results of the query. See Supported Sorting Options for more details.
`sort_order`	`string`	`ascending, descending`	Specifies the ordering to be used when sorting the results of the query. The default value varies based on the value of the `sort_by` parameter. See Supported Sorting Options for more details

Supported Sorting Options

The ordering of the results returned by a query request can be changed by specifying sort_by and sort_order parameters. Any of the following values are valid when specifying the sort_by parameter. For a complete list of fields involved in list queries, see List in Object Field References.

Value	Default Sort Order	Description
`created_at`	`descending`	Specifies that the query results should be sorted by the lists' `created_at` timestamps
`id`	`ascending`	Specifies that the query results should be sorted by the lists' `id` fields
`name`	`ascending`	Specifies that the query results should be sorted by the lists' `name` fields
`updated_at`	`descending`	Specifies that the query results should be sorted by the lists' `updated_at` timestamps

</rsp>

Tag	Description
`<result>`	Contains the resulting lists for the specified query
`<total_results>`	Contains the number of lists selected by this query. If this value is higher than 200, then several query requests may be necessary to retrieve all of the matched lists
