> Visit counts for the last ten days, one entry per day, oldest first.

  title: Vizito API
  version: 1.0.0
  description: |
    Read and write your Vizito visitor data over HTTPS.

    Every endpoint takes and returns JSON, and is authenticated with an API key
    created by a global admin on the Integrations page of the Backoffice.

    Almost every endpoint names a **location** — `company_id` in the API. Your
    key is pinned to a set of locations; naming one outside that set is refused
    with `403`. Start at `GET /companiesList`, the one endpoint that needs no
    location id.
