Otter

Read launch status and current-configuration 7-day sampled change/JS health. These are diagnostic sampled executions, not unique visitors or statistical results. Requires results:read.

Get full results across all goals with optional segment filters.

Get a simplified summary for the primary goal with optional segment filters.

Get daily time series data for charting with optional segment filters.

Read current launch checks and duration assumptions before starting or resuming. Unknown verification is a warning; only explicit customer A/A intent may acknowledge identity.

Mint signed human preview links for saved variants. Requires a verified snippet and a concrete matching URL. No Otter conversion tracking; a settled preview does not prove startup timing.

Get details for a specific project by ID.

Get installation metadata, SDK snippets, and verification status for a project.

Get aggregate statistics for a project, including lifetime totals and last-30-day metrics.

Load one of the project's own pages in a real browser and return its elements with working CSS selectors. Call this BEFORE authoring visual changes: a selector that matches nothing applies no change and fails silently, leaving the variant identical to the control. Use the returned selector values verbatim.

List supported experiment types.

List experiments for a project, optionally filtered by status.

List supported goal types.

List all projects accessible to this API key. Returns paginated results.

List available targeting fields and operators for building targeting rules.

List supported visual change actions.

Pause a running experiment. New visitors will not be assigned while paused.

One-step creation of a redirect A/B test.

One-step creation of a visual A/B test with element changes.

Resume a paused experiment.

Start a draft experiment. Requires at least 2 variants and 1 goal.

Update a draft or paused experiment's configuration; on a paused experiment, include existing variant, change, and goal IDs to keep them. Its status is unchanged unless start_immediately (draft) or resume_immediately (paused) is true, which runs launch preflight and runs it on the live site.

Update a project. Only provided fields are changed.

Verify saved visual/personalization challengers with the real SDK mutations in fresh desktop/mobile contexts. Persists current configuration evidence; partial/unknown runs cannot pass. At most four variant/viewport combinations per call. Requires experiments:write.
