Plaid Categories API is one of 31 APIs that [Plaid](https://apis.io/providers/plaid/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Categories, Transaction, Taxonomy, Financial, and Fintech. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

Plaid's Categories is part of the Plaid open-finance platform, exposing 1 documented endpoint(s) under the Plaid REST API at production.plaid.com. It lets developers securely connect to end users' bank and financial accounts across 12,000+ US and international institutions and consume categories data or actions. Access uses client_id + secret credentials with a Plaid-Version header, an access_token per linked Item, and a real published OpenAPI definition harvested from Plaid's plaid-openapi repository.
