Airbase API
Airbase has a REST API for building custom connections, but its primary integration model is prebuilt native connectors to NetSuite, Sage Intacct, QuickBooks, and Xero. There is no self-serve developer portal or SDKs, and custom API work is positioned as needing dedicated developer resources.
Frequently asked questions
Airbase scores D+ on Supergood's API Report Card. Airbase has a REST API for building custom connections, but its primary integration model is prebuilt native connectors to NetSuite, Sage Intacct, QuickBooks, and Xero. There is no self-serve developer portal or SDKs, and custom API work is positioned as needing dedicated developer resources.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Airbase (now "Airbase by Paylocity") is a modern finance and spend management platform combining accounts payable/bill pay automation, expense management, corporate cards, and procurement.
Spend Management (Financial Services), Typically for mid-market finance and accounting teams at companies in the 100–5,000 employee segment. Finance teams route purchase requests and bills through approval workflows, issue physical/virtual corporate cards, manage employee expense reports, and auto-sync approved transactions to NetSuite, Sage Intacct, QuickBooks, or Xero GLs for faster close.
500+ clients averaging 200+ employees; ~300 staff; acquired by Paylocity for ~$325M (Oct 2024). Recognizable mid-market brand, though G2 review pages were removed post-acquisition.

Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Yes, via a managed API layer. Supergood builds REST APIs and MCP servers for authenticated enterprise web apps, so AI agents and internal tools can read and write data programmatically. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Not that we could find. As of August 2026 there is no official Airbase MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Airbase doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
