Take third-party pixels off your site and ad platforms go blind, which is why most privacy migrations stall. Otus forwards conversions to their server-side APIs instead, so optimisation keeps running and nothing from Google, Meta, TikTok or OpenAI ever loads in your visitors' browsers. You are in full control of what you actually send.
Request accessGoogle Ads & GA4
Connect via OAuth and pick a conversion action or GA4 web stream. Events are matched on gclid, gbraid or wbraid.
Meta Conversions API
Purchases, sign-ups, leads and add-to-cart events map to Meta's standard events automatically, matched on fbclid.
TikTok Events API 2.0
The same event set flows to TikTok's Events API, matched on ttclid, no separate implementation required.
ChatGPT (OpenAI Ads)
Send conversions for ads shown on ChatGPT through OpenAI's Conversions API, connected the same way as the rest.
One event pipeline, four destinations. Standard events like purchase, sign_up and add_to_cart are translated into each platform's own vocabulary automatically; anything else is forwarded as a custom event using the name you already track it under.
Every event is off by default. From Settings, connect a platform and flip on the exact events you want it to see, purchases to Google, leads to Meta, whatever fits. Each connection shows how many events were sent and how many failed in the last 7 days, so nothing silently stops working.
No pixels, no client-side tags
Conversions leave from our servers after ingestion. Ad blockers, ITP and Safari's tracking prevention have nothing to catch, because nothing loads in the browser.
Matched without collecting PII
Otus doesn't collect emails or phone numbers to hash. Matching uses the click ID already present in the URL (gclid, fbclid, ttclid) plus IP and user agent, the same signal the ad platform already sees.
Retried automatically, surfaced when it can't be
Transient failures are retried in the background. A rejected credential pauses that connection and flags it in Settings for reconnection, instead of quietly dropping events.
Server-side conversion forwarding is included on the PRO plan and above, connect Google Ads, Meta, TikTok and ChatGPT from one place, with per-event control over what each platform receives.
