Optionally include the rule's current compliance score via the `include=score` query parameter. Rules belonging to other organizations cannot be retrieved. This endpoint requires any of the following permissions: `telemetry_rules_read``metrics_read` ### Arguments #### Path Parameters | Name | Type | Description | | ------------------------- | ------ | -------------------------------------- | | rule_id [*required*] | string | The unique identifier of the tag rule. | #### Query Strings | Name | Type | Description | | -------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- | | include | enum | Comma-separated list of related resources to include alongside the rule. Currently the only supported value is `score`. Allowed enum values: `score` | | ts_start | integer | Start of the time window used for compliance score computation, as a Unix timestamp in milliseconds. | | ts_end | integer | End of the time window used for compliance score computation, as a Unix timestamp in milliseconds. Must be in the past and greater than `ts_start`. | ### Response {% tab title="200" %} OK {% tab title="Model" %} A single tag rule. | Parent field | Field | Type | Description | | ------------- | ------------------------------------ | --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | data [*required*] | object | A tag rule resource. | | data | attributes [*required*] | object | The attributes of a tag rule resource. | | attributes | created_at [*required*] | date-time | The RFC 3339 timestamp at which the rule was created. | | attributes | created_by [*required*] | string | The identifier of the user who created the rule. | | attributes | deleted_at | date-time | The RFC 3339 timestamp at which the rule was soft-deleted. `null` if the rule has not been deleted.
