Extend
APIs, MCPs and integrations to build on top.
APIs for custom storefronts and back-office automation, MCP servers for AI-native workflows, automations and pre-built connectors for third-party platforms.
APIs
Programmatic access, front to back.
RESTful APIs for storefront and admin use cases — build custom checkout flows or sync Supercycle data with your internal stack.
Admin API
Full programmatic access to your Supercycle data. Manage products, inventory, rentals, returns, charges and custom fields from your internal systems or automation layers. RESTful endpoints with pagination and API key authentication. Build product imports, sync items to ERPs, or extend Supercycle functionality programmatically.
Authenticate with API keys you control through scoped credentials, stream large datasets safely with cursor-based pagination, and operate on every serialised unit and rental through the Items and Rentals endpoints.
Storefront API
Build custom storefront experiences with real-time availability, pricing and rental intent. Create bespoke checkout flows while Supercycle handles availability checks, cycle creation and payment orchestration in the background. Query availability timelines, set rental intent tokens, and build storefronts beyond the standard Shopify theme.
Render real-time calendars with availability timelines, surface stock at a glance via product availability, and lock customer selections through cart and checkout with a signed rental intent token.
AI
MCP servers for AI-native workflows.
Connect Claude, ChatGPT or any MCP client to Supercycle — for building integrations or running operations from natural language.
Operators MCP
Connect your AI assistant directly to your Supercycle data. Query cycles, inventory, customers and returns using natural language. Read tools are auto-approved; write tools request confirmation before making changes. Works with Claude, ChatGPT and any MCP-compatible client via OAuth.
Connect in minutes via OAuth — no API keys to manage. Read across cycles, inventory, customers and returns through a curated tools surface, with write actions gated by an explicit-confirmation security model.
Builders MCP
Give your AI tools direct access to Supercycle's documentation and API reference. Build integrations faster with structured, up-to-date context — no web searching required. Read-only and unauthenticated, the Builders MCP plugs into any AI tool that supports MCP.
Read-only and unauthenticated — drop it into Claude, Cursor or any MCP-compatible tool in seconds and ship integrations without a tab full of doc pages.
Automations
Trigger workflows on any event.
Supercycle plugs straight into Shopify Flow as our workflow engine, with pre-built connectors for the rest of your operational stack.
Shopify Flow
Shopify Flow is our workflow engine. Drop Supercycle triggers and actions into Flow alongside your existing automations to react to rental events, charge changes, returns, contract signatures and more — and combine them with the broader Shopify ecosystem in a single workflow tool. Send Slack notifications, update tags, sync to external systems, all without writing code.
Connectors
Pre-built integrations for platforms like Patchworks enable no-code connections to 3PLs, ERPs and other third-party systems. Deploy in minutes with templated connectors. For deeper integrations, the Admin API provides full programmatic access.
Custom data
Extend the data model.
Capture business-specific data on items and cycles, and bridge to your wider stack via Shopify metafields.
Custom fields
Add custom fields to items and cycles to capture data specific to your business — sizing, fabric notes, condition specifics, internal references, anything else you need. Surface them in admin views, use them in workflows or read and write through the API.
Spin up new attributes on the fly with the custom fields API, and bridge to your existing Shopify model via metafields so circular data flows the same place as everything else.
Frequently asked questions.
What can I build with the Admin API?
The Admin API gives full programmatic access to products, inventory, rentals, returns, charges, custom fields and more. Use it for back-office integrations, automation layers, data sync with ERPs, or building custom internal tools.
What's the difference between the two MCP servers?
The Builders MCP gives AI tools read-only access to Supercycle documentation and API reference — useful when building integrations. The Operators MCP connects your AI assistant to your live Supercycle data so you can query and manage operations using natural language.
Do I need to write code for integrations?
Not always. Pre-built connectors for platforms like Patchworks enable no-code integrations with 3PLs, ERPs and other systems. Automations and Shopify Flow provide trigger-and-action workflows without code. The APIs are there when you need deeper customisation.
Which AI assistants work with the Operators MCP?
The Operators MCP works with Claude, ChatGPT and any MCP-compatible client. It uses OAuth authentication with your Shopify account. Read tools are auto-approved; write tools request confirmation before making changes.
What can I add custom fields to?
Custom fields can be added to items and cycles to capture data specific to your business — sizing, fabric notes, condition specifics, internal references and more. Use them in workflows, in reporting or via the API.
