  title: Fulcrum Audio Signatures API
  description: The Fulcrum API is a RESTful HTTP API for the Fulcrum field data collection platform. It provides programmatic access to forms, records, media (photos, videos, audio, signatures), choice lists, classification sets, projects, layers, memberships, roles, webhooks, ad hoc query and SQL execution, and changesets. Requests and responses use JSON and authenticate with an X-ApiToken header issued from a Fulcrum account.
