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 the 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.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Airbase API and MCP server so AI agents and internal tools can read and write Airbase data. See the Airbase integration docs at supergood.ai/docs/airbase-api.
