At build.octany.com you'll find Octany's full developer documentation.
The documentation is built to be just as useful for AI agents as for developers. Every page is also available as plain markdown, and the site has an llms.txt file that summarizes the content and gives clear rules for how to best integrate with Octany - perfect to point an AI coding agent at if you're building an integration.
What you'll find there
Overview - integration paths, core billing concepts, and an overview of REST endpoints
Fundraising - Donation, 1-click Swish, and Greeting widgets for campaign pages and editorial content
Checkout - hosted checkout, query parameters, success/redirect handling, the window.Octany JavaScript API, and the embeddable cart
Classic widget - the classic <octany-widget> element, attribute reference, iframe vs. button mode, and the postMessage protocol
Webhooks - event catalog (subscription.*, order.*, product.*), example payloads, and how to verify the HMAC-SHA256 signature
API - full REST API reference with endpoints, request bodies, and response examples
The documentation is also available in Swedish.
