For AI products · Headless and API-first

Build AI products and SaaS. Automate with Donutwork.

Donutwork is a headless, API-first platform for AI products and business automation. AI Gateway brings together connections, assistants, retrieval, and usage; recurring billing, workflows, partner networks, and integrations share the same core. Connect it to your software or use it as the foundation for your next product.

Move from business logic to a working system in 3 steps: define entities and processes, connect your software through APIs, then deploy and scale. The 12 platform areas cover the capabilities along that path. When you want implementation details, start with 3 entry points and documentation in English and Italian.

  • AI Gateway
  • Subscription billing
  • Workflow automation

One core, connected capabilities

Donutwork connects 12 platform areas through a headless, API-first backend. The Help Center highlights 3 capabilities and lists 9 more areas to explore in the guides.

Billing covers plans, renewals, and metering; workflows include approvals and retries; Partner Program covers referrals, commissions, and payouts. AI Gateway includes connections, assistants, retrieval, and usage. You can integrate these capabilities into your software through REST APIs and webhooks, then use the guides to follow the SaaS or automation flow you need.

Build on an API-first backend

Donutwork’s versioned REST APIs connect your software, CRM, or product to the platform core. Each guided path lists its required scopes, and the API key stays on your server.

The 3 guided flows show how to attach a customer to a plan, receive payment events and reconcile a charge, and send a transactional email. The examples use API version 2026-02-01; the request beside this text calls the ping endpoint with Bearer authentication.

API request example
curl 'https://api.hub.donutwork.com/2026-02-01/ping.json' \
  -H "Authorization: Bearer $DONUTWORK_API_KEY"
