Querying Lifecycle Histories

Supported Operations

Operation	URL Format	Required Parameters	Description
`query`	`/api/lifecycleHistory/version/3/do/query?...`	`user_key, api_key`	Returns the lifecycle history matching the specified criteria parameters. See the Using Lifecycle Histories section for a complete description of the lifecycle history XML Response Format. Also see Lifecycle History 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 lifecycle histories 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 lifecycle histories 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 lifecycle histories 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 lifecycle histories with IDs greater than the specified integer
`id_less_than`	`integer`	`<any_positive_integer>`	Searches for lifecycle histories with IDs less than the specified integer

Manipulating the Result Set

Since query result sets are limited to 200 results each, the results returned may not include all the lifecycle histories 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 lifecycle history (according to the specified sorting order) to be returned in the `query` response. The first `offset` matching lifecycle history will be omitted from the response. Default value: `0`. *Example:* Specifying `offset=10` will return the results starting with the 11th lifecycle history 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 Supporting 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 lifecycle history queries, see Lifecycle History in Object Field References.

Value	Default Sort Order	Description
`created_at`	`ascending`	Specifies that the query results should be sorted by the Lifecycle Histories' `created_at` timestamps
`id`	`ascending`	Specifies that the query results should be sorted by the Lifecycle Histories' `id` fields

XML Response Format

<rsp stat="ok" version="1.0">
    <result>
        <total_results>...</total_results>
        <lifecycleHistory>...</lifecycleHistory>
        <lifecycleHistory>...</lifecycleHistory>
        <lifecycleHistory>...</lifecycleHistory>
    </result>
</rsp>

Tag	Description
`<result>`	Contains the resulting lifecycle histories for the specified query
`<total_results>`	Contains the number of lifecycle histories selected by this query. If this value is higher than 200, then several query requests may be necessary to retrieve all of the matched lifecycle histories
`<lifecycleHistory>`	The data for an individual lifecycle history. See Using Lifecycle Histories for a complete description of the lifecycle history XML Response Format. Also see Lifecycle History in Object Field References

Supported Operations

Operation	URL Format	Required Parameters	Description
`read`	`/api/lifecycleHistory/version/3/do/read/id/`*`<id>`*`?...`	`user_key, api_key, id`	Returns the data for the lifecycle history specified by `<id>`. `<id>` is the Pardot ID of the target lifecycle history.

Tag	Description
`<lifecycleHistory>`	Parent tag. Contains data fields for target lifecycle history. For complete field listing, see Lifecycle History in Object Field References.
