description: Airbase is a modern spend management platform for finance teams that combines accounts-payable (AP) automation
  and bill pay, guided procurement and purchase orders, corporate cards, and expense reimbursements on a single system with
  real-time general-ledger sync. Airbase Inc. was acquired by Paylocity in a ~$325M deal announced September 4, 2024 and completed
  October 1, 2024, and now operates as "Airbase by Paylocity," extending Paylocity's HCM suite into the office of the CFO.
  Airbase exposes a developer platform at developer.airbase.io (REST API reference, OpenAPI/Swagger, Postman and Insomnia
  collections, a webhooks management API, an OAuth playground, and a sandbox) used to build custom connections for systems
  not covered by the pre-built integrations. API access is account-gated - credentials are generated inside the customer's
  Airbase/Paylocity tenant rather than through open self-serve signup - so the logical APIs below are honestly modeled from
  the documented product surface and developer portal, and the exact endpoint paths and base URL are not publicly reproduced
  here (endpointsModeled).
