List conversion destinations

Returns the list of pixels (Meta), conversion actions (Google), conversion rules (LinkedIn), or pixels (OpenAI Ads) accessible to the connected ads account. Use the returned id as destinationId when posting to POST /v1/ads/conversions.

For Google and LinkedIn, each destination's type reflects the conversion type (PURCHASE, LEAD, SIGN_UP, etc.) — the event type is locked to the destination. For Meta and OpenAI Ads, type is absent: pixels accept any event name per request.

For LinkedIn, destinations are returned across every sponsored ad account the connected token can access; the adAccountId field on each destination identifies the parent ad account and is required for subsequent CRUD calls (update, delete, associations, metrics).
