-Welcome to the Affinity API! This API provides a RESTful interface for performing operations on the different objects that make up Affinity. If you are trying to accomplish an action through this API and are not sure on what endpoints to use, or if you have ideas on more endpoints we could create to make your workflow easier, please do not hesitate to contact us at [support@affinity.co](mailto:support@affinity.co).
+Welcome to the Affinity V1 API! This API provides a RESTful interface for performing operations on the different objects that make up Affinity. The latest Affinity API (v2) can be found at https://developer.affinity.co. The v2 API is not at feature parity with v1 - we are continuing to develop new v2 APIs to support all v1 functionality over time.

 ### Query Parameters
 
 | Parameter | Type | Required | Description |
 | --- | --- | --- | --- |
 | field_id | integer | true | A unique ID that represents a field object whose field values changes are to be retrieved. |
 | action_type | integer | false | An integer that filters field value changes that were created with this specific action type (see above). |
-| person_id | integer | custom* | A unique ID that represents a person object whose field value changes are to be retrieved. |
-| organization_id | integer | custom* | A unique ID that represents an organization object whose field value changes are to be retrieved. |
-| opportunity_id | integer | custom* | A unique ID that represents an opportunity object whose field value changes are to be retrieved. |
-| list_entry_id | integer | custom* | A unique ID that represents a list entry object whose field value changes are to be retrieved. |

+| opportunity_id | integer | false | A unique ID that represents an opportunity object whose field value changes are to be retrieved. |
+| list_entry_id | integer | false | A unique ID that represents a list entry object whose field value changes are to be retrieved. |
+| changed_after | datetime | false | A timestamp that filters field value changes created at or after that time. |
+| limit | integer | false | An integer number that restricts the field value changes being returned. |
 
 #### Returns
 
 An array of all the field values changes associated with the supplied field and `person`, `organization`, `opportunity` or `list_entry` if specified.
 
 #### Notes
 
-> - Exactly one of `person_id`, `organization_id`, `opportunity_id`, or `list_entry_id` must be specified to the endpoint.
-> - If a `person_id`, `organization_id`, or `opportunity_id` is specified, the endpoint returns all field value changes tied to these entities.
+> - The response is default-sorted by `changed_at` in descending order, ensuring that the most recent field value changes are returned first.
+> - The response may be filtered by providing at most one of the following parameters: `person_id`, `organization_id`, `opportunity_id`, or `list_entry_id`. If none are specified, the response encompasses all data for the given `field_id` across the organization. For fields with high volumes of data, organization-wide queries may be subject to timeouts; in these cases, the use of the `changed_after` and `limit` parameters is recommended.
+> - If a `person_id`, `organization_id`, or `opportunity_id` is specified, the endpoint returns all field value changes for the provided `field_id` tied to these entities.
 > - If a `list_entry_id` is specified, the result is filtered by the `person_id`, `organization_id` or `opportunity_id` which is tied to the specified `list_entry_id`.
