Try in playground
POST/api— body field action.name = "get_dtc_events"

Parameters

NameTypeRequiredDescription

group_liststringoptionalComma-separated list of group ids.e.g. 10,11
vehicle_id_liststringoptionalComma-separated list of vehicle ids.e.g. 555,556,557

to_datedateoptionalEnd of date range. Defaults to now when omitted.e.g. 2026-04-27T00:00:00Z

Notes

env_id is taken from the session only — no parameter override. At least one of `license_list`, `group_list`, or `vehicle_id_list` is required. Date defaults: `to_date` defaults to now and `from_date` defaults to `to_date - 3 days`. Window > 72 hours returns action_value '1'. `recommendation`, `duration`, `first_occured`, `last_occured` are returned as empty strings (no PG analog).
