Supports schedules with multiple concurrent on-call responders at a position, by returning a list of shifts per position. This endpoint requires the `on_call_read` permission. ### Arguments #### Path Parameters | Name | Type | Description | | ----------------------------- | ------ | ----------------------- | | schedule_id [*required*] | string | The ID of the schedule. | #### Query Strings | Name | Type | Description | | ---------------- | ------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | include | string | Comma-separated list of included relationships to be returned. Allowed values: `schedule`, `responders`, `responders.shifts`, `responders.shifts.user`. | | filter[position] | string | Comma-separated list of positions to retrieve. Allowed values: `previous`, `current`, `next`. Defaults to `current` if omitted. | | filter[at_ts] | string | Retrieves the on-call responders at the given timestamp in RFC3339 format (for example, `2025-05-07T02:53:01Z` or `2025-05-07T02:53:01+00:00`). When using timezone offsets with `+` or `-`, ensure proper URL encoding (`+` should be encoded as `%2B`). Defaults to the current time if omitted. | ### Response {% tab title="200" %} OK {% tab title="Model" %} Root object representing a schedule's on-call responders, grouped by position (previous, current, next), for a given point in time. | Parent field | Field | Type | Description | | -------------------------------- | -------------------------------- | --------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | data | object | The main data object representing a schedule's on-call responders lookup, including relationships and metadata. | | data | attributes | object | Attributes for a schedule's on-call responders lookup. | | attributes | scheduled_at | date-time | The timestamp the responders were resolved at. | | data | id | string | Unique identifier of this on-call responders lookup. | | data | relationships | object | Relationships for a schedule's on-call responders lookup, including the schedule and its responder groups. | | relationships | responders | object | Defines the list of per-position (previous, current, next) responder groups for the schedule. | | responders | data | [object] | Array of references to the responder groups included in the response. | | data | id [*required*] | string | Unique identifier of the responder group. | | data | type [*required*] | enum | Identifies the resource type for a responder group linked to a schedule's on-call responders lookup.
