List TikTok pixels and their events

Lists the pixels on the advertiser account, the events each one is configured for, and whether TikTok reports the pixel as having any recent activity. Use when: a campaign will optimise for conversions, the user asks whether tracking works, or a report shows spend with no conversions. Always call it before creating a WEB_CONVERSIONS campaign — the pixel id and event name it returns are the only valid values for that create. Do not pick an event just because it exists. An event with no recent activity will not train TikTok's optimisation: the campaign stays in the learning phase, spends at a high CPA and never settles. Prefer an event firing at least a few dozen times a week, and say so if none does. Do not conclude that ads are failing when every campaign reports zero conversions and this tool shows a pixel with no recent activity — that is a measurement problem, and pausing campaigns will not fix it. Returns the pixel id and code, the events it can optimise for, and the standard event vocabulary TikTok accepts. TikTok publishes no per-event counts or timestamps on this endpoint, so "is it firing" is only answered at pixel level; confirm the specific event in TikTok Events Manager. Costs nothing.
