- Conversion
- An action you told an ad platform to count and optimise for. For TapTime it is a confirmed reservation or appointment the guest made online.
- Server-side conversion tracking
- Reporting the conversion from a server to the platform's API instead of from a script in the guest's browser, so it is not lost to ad blockers, privacy settings or a closed tab.
- gclid, gbraid, wbraid
- Google's click identifiers, added to the ad's landing URL. gclid is the classic one; gbraid and wbraid are the privacy-preserving variants from iOS app campaigns and web campaigns. Google Ads can only credit an uploaded conversion to a click it recognises by one of them.
- fbclid, fbp, fbc
- Meta's click id in the URL, the browser id cookie the pixel sets, and the click cookie built from fbclid. All three help the Conversions API match a booking to the ad click.
- Google Ads click conversion upload
- The Google Ads API method (uploadClickConversions) a server uses to report a conversion for a specific click, with the click id, time, value and an order id used for deduplication.
- ttclid, msclkid
- TikTok's and Microsoft's click identifiers, added to the ad's landing URL by auto-tagging. The TikTok Events API and the Microsoft Conversions API use them to credit a booking to the ad click that earned it.
- Meta Conversions API (CAPI)
- Meta's server-to-server endpoint for events. Each event carries an event_id; when the pixel sends the same event with the same id, Meta keeps one.
- GA4 Measurement Protocol
- Google Analytics 4's HTTP endpoint for server events. An event joins the visitor's session when it carries the client id and session id from the GA cookies and the session is less than about 72 hours old.
- Key event
- GA4's name for a conversion. An event only counts as a conversion in GA4 reports and in Google Ads bidding after you mark it as a key event under Admin → Events.
- Event deduplication
- Sending one shared identifier with the browser event and the server event so a platform that receives both counts a single conversion.
- UTM parameters
- utm_source, utm_medium, utm_campaign, utm_term and utm_content: tags you add to your own links so a booking remembers the post, newsletter, flyer or partner that brought the guest.
- Webhook
- An HTTP request TapTime sends to a URL you own whenever something happens, with the full details in JSON and a signature to verify it.
- Postback (server-to-server pixel)
- A URL provided by an ad network or tracker that the advertiser's server calls on each conversion, with the tracker's click id and the payout filled into placeholders.
- HMAC-SHA256 signature
- A keyed hash of the request body and a timestamp, computed with a shared secret. Recomputing it on your side proves the request came from TapTime and was not altered.
- At-least-once delivery
- The guarantee that every event is delivered, with the trade-off that a retry can deliver one twice. That is why every TapTime event carries an id to ignore duplicates by.
- Offline conversion
- A conversion that happens outside the browser session, such as staff confirming a request the next day. TapTime sends it at the moment of confirmation with the original click id.
