The REST API

Your spend data, on tap.

Everything Groundley reads and categorises is available over a clean REST API: invoices and invoice lines, the spend category tree, suppliers, and the emissions that come with them. Authenticate with a bearer token, page through the data, and subscribe to webhooks for anything new.
