  title: Octobat Coupons Transactions API
  description: 'Octobat is a billing, invoicing, and tax-compliance platform for online businesses. This OpenAPI document describes the public REST API at base URL https://apiv2.octobat.com. The API is Stripe-style: resource-oriented, form or JSON request bodies, and HTTP Basic authentication using your secret key as the username with an empty password (curl: -u sk_live_xxx:). Test-mode keys (sk_test_) and live-mode keys (sk_live_) select the environment.


    Endpoint provenance: paths marked "confirmed" are demonstrated directly in Octobat''s own documentation (register-transactions and tax-calculation guides). The remaining CRUD and action paths are modeled from Octobat''s official Ruby SDK (github.com/0ctobat/octobat-ruby), which derives resource URLs as the snake_cased, pluralized class name and uses POST to create, PATCH to update, GET to retrieve/list, and DELETE to remove. Request and response schemas are representative, not exhaustive; consult the live API reference at https://v2apidoc.octobat.com for full field-level detail.


    Operating status: Octobat was acquired by Mirakl in November 2021. The standalone marketing site now redirects to mirakl.com; docs.octobat.com and apiv2.octobat.com remain available to existing integrators.'
