Application Programming Interface

An API defines how one system requests data or actions from another. In legal technology, APIs connect case management, document management, e-billing, review platforms, and analytics tools.

Availability, documentation quality, and rate limits vary substantially between vendors.

Alternative Names:

API, Integration API

Why it Matters?

API availability determines whether a firm's systems form a connected environment or a set of silos requiring manual re-entry. It is worth evaluating during procurement rather than after, since vendors without meaningful APIs create permanent operational friction. For AI tools specifically, API access to the matter file is what allows analysis to work from current documents rather than a stale copy someone uploaded.
