  title: Instapage Experiments API
  description: 'A/B and AI experiments running against landing pages.


    The Instapage Public API is a REST API over the Instapage landing page and post-click optimization
    platform. It exposes workspaces, team members, landing pages, page groups, personalized experiences,
    collections and collection pages, experiments, analytics, form submissions (leads), custom domains
    and image assets.


    Authentication is a personal API token sent as an HTTP Bearer token in the Authorization header. A
    personal token inherits all permissions from its creator and cannot exceed them; expired or revoked
    tokens return 401. Rate limiting is 200 requests per minute enforced per token and per IP address,
    on top of a daily plan quota that resets at 00:00 UTC; exceeding either returns 429 with a Retry-After
    header.


    List endpoints are page-number paginated via the `page` query parameter and return a `meta.pagination`
    block; form submissions instead use an opaque `meta.nextPageToken` cursor. Errors are returned as
    a `{title, details, meta}` envelope.
