Registration Completed is a standard ChatGPT Ads conversion event that fires when someone finishes creating an account or registering for something on your site after clicking your ad. It marks a sign-up as a customer action, so it carries only an optional value and currency, unlike order_created, which expects a full cart and purchase total.
If you run product-led or event-driven campaigns, you decide whether to optimize delivery toward this event or a deeper action like a paid order or trial. Get the setup wrong and OpenAI counts phantom registrations on every page load, training its bidding on noise and burning budget.
Within OpenAI's event taxonomy, the Registration Completed event belongs to the customer_action data shape, the group for sign-up and lead actions that carry no product payload. You fire it the moment a visitor finishes an account creation or event registration, and you can attach an optional value and currency when the registration has business worth.
The event travels two ways. A browser pixel called oaiq sends it when the confirmation page loads, and OpenAI's server-side Conversions API can send the same event from your backend for reliability. When both fire for one registration, a shared event_id lets OpenAI deduplicate them so the conversion is counted once. Because it is a standard event, you can also nominate it as the optimization goal for a conversion campaign.
Registration Completed sits between lightweight signals like page_viewed and revenue events like order_created: it confirms real intent without waiting for a purchase. Teams pair this event with downstream analytics, and AirOps helps marketers monitor how their brand surfaces across AI search so paid and organic ChatGPT visibility inform the same funnel.

The Registration Completed event moves from a user action on your site to a counted conversion in Ads Manager through a fixed sequence.
Install the pixel: Place the oaiq base pixel on every page so OpenAI can recognize visitors who arrived from a ChatGPT ad.
Define the trigger: Decide the single moment that counts as a completed registration, usually the confirmation or welcome page, so the event fires once per sign-up.
Fire the event: When a visitor reaches that trigger, send registration_completed with an optional value, currency, and a unique event_id.
Send server-side: Post the same event from your backend through the Conversions API with the matching event_id so OpenAI deduplicates the browser and server copies.
Attribute and optimize: OpenAI ties the conversion to the originating ad click within its attribution window and, if you chose this event as your goal, feeds it into oCPC bidding.
The counted total tells you how many sign-ups your ChatGPT ads drove and which campaigns produced them. It stops short of showing revenue, so pair it with a revenue event like order_created when lifetime value matters.
Choosing Registration Completed as your conversion signal is a budgeting decision. It tells OpenAI which outcome to chase with your money, and it sets the benchmark you will judge every campaign's cost and efficiency against.
It optimizes delivery toward real sign-ups. When you nominate this event as your oCPC goal, OpenAI biases clicks toward people likely to register, so spend concentrates on account creation instead of raw traffic that never converts.
It exposes a common tracking failure. Registration Completed is the default example in OpenAI's pixel snippet, so teams that paste the full block leave it firing on every page load, inflating conversions and poisoning the bidding model with fake sign-ups it can never unlearn.
It bridges ChatGPT ads to product activation. For product-led SaaS, the account is the conversion, so this event ties ad spend directly to the first activation step your funnel depends on.
Growth marketers use the Registration Completed event to optimize ChatGPT ad delivery toward account sign-ups for a product-led free trial.
Demand gen leads use the Registration Completed event to measure how many webinar and event registrations each ChatGPT campaign produced.
SEO managers use the Registration Completed event to compare paid ChatGPT sign-up rates against organic AI-referral conversions in one view.
The Registration Completed event uses OpenAI's customer_action data type, which accepts only an optional value and currency and rejects the product array that commerce events like order_created require, so you never attach a cart or item list to a sign-up.
Sending the same registration from both the browser pixel and the Conversions API with one shared event_id lets OpenAI merge the two copies so a single sign-up is never counted twice, which keeps your conversion totals and cost-per-registration honest.
Because it is a standard event, Registration Completed can serve as the optimization goal of a conversion campaign, which a custom event can never do, which is why your optimization event must be a standard one.
Connects ChatGPT ad spend to real account sign-ups instead of raw clicks.
Qualifies as an oCPC optimization goal, so OpenAI can bid toward registrations.
Deduplicates browser and server events through a shared event_id for accurate counts.
Works across the OpenAI pixel and the Conversions API for resilient tracking.
Benchmarks paid ChatGPT performance against organic AI-referral sign-ups in Google Analytics 4.
Fire the event only on the confirmation step, so a registration counts exactly once per completed sign-up.
Send a unique event_id from both pixel and Conversions API, so OpenAI deduplicates the matched pair.
Add the server-side Conversions API alongside the pixel, so ad blockers and lost cookies do not hide conversions.
Attach a value and currency when a registration has clear worth, so OpenAI can weigh higher-value sign-ups more heavily.
Run the Conversions API and pixel with the same definition of registered, so both sources agree on what counts.
Keep one campaign per optimization event, because mixing goals splits the learning OpenAI needs to bid well.
Avoid pasting OpenAI's full example snippet onto every page and leaving the sample registration_completed event in place; it fires on every page load, turns ordinary visits into phantom registrations, and trains oCPC bidding on data that means nothing.
AirOps: Tracks how your brand appears across ChatGPT and other AI search engines, so paid Registration Completed data sits next to the organic visibility driving the same sign-ups.
OpenAI Conversions API: Sends the registration_completed event server-side with a matching event_id, recovering conversions the browser pixel misses to ad blockers.
Google Tag Manager: Deploys and triggers the oaiq pixel's registration_completed event on the confirmation page without hard-coding it into every template.
Install the base pixel: Add the oaiq snippet to every page this week; it needs no budget approval and starts recognizing ChatGPT ad visitors immediately.
Pick your trigger: Identify the single confirmation or welcome page that marks a finished registration, so the event has one unambiguous firing point. It should never fire on ordinary pages.
Fire registration_completed: Configure the event on that trigger with an optional value, currency, and a unique event_id generated per sign-up. Keep that event_id consistent so the server copy can match it later.
Add the Conversions API: Post the same event from your server with the matching event_id so OpenAI deduplicates and recovers conversions the pixel loses.
Set it as your goal: Once the event records clean data, nominate registration_completed as your conversion campaign's oCPC goal and watch delivery shift toward sign-ups. Keep each campaign to a single goal so the model learns cleanly.
Registration Completed is a standard ChatGPT Ads conversion event that marks a completed account or event sign-up.
It is measured reliably through the OpenAI pixel and Conversions API, deduplicated by a shared event_id across both sources.
The event accepts only an optional value and currency, never a product cart, because it is a customer action.
Its biggest risk is the default snippet firing on every page and manufacturing fake registrations that corrupt bidding.
The leverage is naming it your oCPC goal so ChatGPT ad spend concentrates on genuine sign-ups.
The Registration Completed event marks a finished account or event sign-up, while the Lead Created event marks an earlier expression of interest such as a form fill or demo request. Both share the customer_action data shape, so both carry an optional value and currency with no product cart, but they sit at different funnel depths. Lead Created usually fires when someone hands over contact details; Registration Completed fires once they actually create an account or secure a spot. The practical difference shows up in optimization: if you bid toward Lead Created, OpenAI chases volume at the top of your funnel, and if you bid toward Registration Completed, it chases a deeper commitment that correlates more closely with activation. Choose Lead Created when your sales motion starts with a conversation, and choose Registration Completed when the account itself is the moment that matters. Running both as goals means two separate campaigns, two budgets, and two independent learning phases.
Fire the Registration Completed event exactly once, at the moment the sign-up is confirmed, never when the registration form loads or a button is clicked. The reliable trigger is the confirmation or welcome page that only loads after the account is actually created, because anything earlier counts intentions that may never finish. Firing on form submission can double-count if the user retries, and firing on page load counts people who never registered. For most sign-up flows that means one event per visitor per completed registration, so your counts match the number of real new accounts. If your registration spans several steps, wait for the final success state instead of any intermediate step. Keep the same definition of a completed registration in both your pixel and your Conversions API calls, so the browser and server never disagree about when the event should fire. Consistency here is what keeps your conversion totals trustworthy enough to optimize against.
Your Registration Completed counts differ between the pixel and the Conversions API because each source catches a different slice of reality, and a gap is normal. The browser pixel misses events whenever an ad blocker, a privacy setting, or a dropped cookie stops it from loading, so it tends to undercount. The server-side Conversions API fires from your backend, so it captures registrations the browser lost, but it can miss events if your server call fails or lacks the identifiers OpenAI needs to match the click. When you send both with the same event_id, OpenAI deduplicates the overlap and keeps one record per sign-up, which is why the deduplicated total usually sits below the sum of the two raw numbers. Large or erratic gaps point to a real problem: a misfiring trigger, inconsistent event definitions, or missing event_ids. Check that both sources describe the same completed registration before you trust either count.
Yes, you can influence how many Registration Completed events your ChatGPT ads drive, though you do not control the number directly. The strongest lever is nominating this event as your conversion campaign's oCPC goal, which tells OpenAI to bias delivery toward clicks likely to end in a registration. Beyond bidding, the creative and the landing experience do most of the work: a clear ad promise matched to a fast, low-friction sign-up page lifts completion more than any targeting tweak. You also influence the count by defining the event cleanly, because a trigger that fires too early or too often reports registrations you did not actually earn. Audience and budget shape the ceiling, since OpenAI can only optimize toward registrations among the people your targeting and spend reach. Treat the event as the outcome you steer toward, then improve the ad, the offer, and the page that produce it.
There is no universal benchmark for a good Registration Completed conversion rate, because it depends on your offer, audience, and how much friction your sign-up carries. A free, single-field registration will convert far higher than one that asks for a credit card or a long profile, so comparing your rate to someone else's is rarely useful. The honest approach is to benchmark against yourself: capture your current click-to-registration rate as a baseline, then judge every change against that number instead of a borrowed industry figure. Watch the trend across a few weeks once OpenAI's bidding has enough registrations to learn from, since early numbers on thin data swing wildly. A healthy sign is a stable or rising registration rate at a cost per registration your unit economics can absorb. If registrations look strong but downstream activation is weak, the rate is flattering you, and you should optimize toward a deeper event instead.
