| Visitor | A person who visits your website. Every visitor gets a user record automatically, whether or not they’re identified. |
| Anonymous visitor | A visitor who hasn’t been identified yet. Their activity is still tracked and kept on their record, and is merged into their identified record if you identify them later. |
| Identified user | A visitor linked to a known user ID or email via the identify call — typically after signing up or logging in. |
| Event | A single action captured on your site: a page view, a click, or a custom event you track. |
| Page view | An event recorded each time a visitor views a page, including route changes in single-page apps. |
| Custom event | An event you define and send with track() — for example “Signed Up” or “Started Checkout”. |
| Session | One visit: the sequence of events a visitor generates from arriving on your site until they leave. |
| Replay | A session recording — a playback of what a visitor saw and did during a visit. |
| Heatmap | A visual overlay showing where visitors click and scroll on a page. |
| Funnel | A sequence of steps (events or page views) used to measure how many visitors convert from one step to the next. |
| Workflow | An automation that triggers actions — like Slack messages or webhooks — based on visitor behavior. |
| UTM parameters | Tags added to URLs (utm_source, utm_medium, utm_campaign…) that identify which campaign brought a visitor to your site. |
| Referrer | The page or site a visitor came from, captured automatically with every event. |
| Object | A type of record (e.g., Users, Accounts). You can create custom objects to fit your data model. |
| Record | A data entry in Bigdelta — one visitor, one account, or one entry of a custom object. |
| Property | A field on a record, like email address or country. Properties can be collected automatically, set via the SDK, or edited by hand. |
| View | A saved configuration of filters, sorting, columns, and layout for browsing records. Each view remembers its settings. |
| Tracking Key | A key that identifies your website in the tracking script. Created in Settings → Access Keys. |
| API Key | A key (with its secret) used for programmatic access to the Bigdelta API. Created in Settings → Access Keys. |
| Sender | A configured email identity (name and address) used in the From field when sending emails from Bigdelta. |
| Webhook | A custom HTTP request sent to an external service, used to connect Bigdelta to other tools. |
