Resources & Support

A curated list of what's actually available to developers and merchants integrating with Ottu. If a link doesn't appear here, it isn't something we publish today — reach out to your account manager for anything you can't find.

Developer Resources​

API Reference​

  • Interactive API Reference — browse every endpoint, view request and response schemas, and try calls directly in the browser.
  • Authentication — API keys, Basic Auth, and Public Key for the Checkout SDK.
  • API Fundamentals — pagination, rate limits, error handling, and amount formatting.
  • Sandbox & Test Cards — the shared sandbox environment and test card numbers for each gateway.

SDKs​

Checkout SDK — embeddable payment UI​

The Checkout SDK collects card details, handles 3-D Secure, and routes payment submission to Ottu. It's available for four platforms:

Server-side integration​

  • Python SDK — Python wrapper around the REST API.
  • Django SDK — Django-specific integration with built-in session management, webhooks, and card operations.
note

Ottu does not publish server-side SDKs for other languages. Integrate directly via REST using the Interactive API Reference — every endpoint page includes request examples in cURL, Python, Node.js, and PHP.
