The InfiPlex OMS API is available two ways on the same API key. The REST API pulls marketplace orders into a custom ERP or WMS and pushes tracking, inventory, and pricing back out, for code you write. The MCP server exposes the same operations as tools an AI agent can call, so Claude, ChatGPT through Codex, Cursor, or any MCP client can run your order management in plain English. Both use the same key, the same read and write scopes, and the same audit trail. Order PII (the ship-to address) is retained only for a limited time after the order is placed, per Amazon's data security requirements, so integrations should pull and store what they need promptly.
Two Ways In, One Key
| REST API | MCP Server | |
|---|---|---|
| Who calls it | Your code: ERP, WMS, scripts, middleware | An AI agent on behalf of a person |
| Endpoint | api.infiplex.com reference; your instance URL from Support | https://yourcompany.infiplex.com/mcp (Streamable HTTP) |
| Auth | Bearer token (your API key) | Same key, as an api-token header or Authorization: Bearer |
| Permissions | Read and write scopes on the key | Same scopes decide which tools exist, plus MCP Enabled and two opt-in flags on the key |
| Write protection | Scopes | Scopes, plus a preview and 10-minute confirmation token on every channel-visible write |
| Cost | Included with the Growth and Enterprise packages | Included wherever API access is; no AI add-on or per-call fee |
MCP Server: Connect Your AI Agents to InfiPlex
Enable MCP on an API key at Tools > Admin API, paste the instance URL and header into your assistant, and it discovers every tool the key allows: order search and detail, the warehouse routing explanation for any order, inventory by warehouse with change history and the restock list, prices, product records, warehouses, settings, the shop log, marketplace connect links, and the writes behind a preview. Start with a read-only key. Full detail:
- InfiPlex MCP Server: what it is, a live demo, and who it is for
- Watch a Demo: Claude on a live InfiPlex instance, recorded
- Is It Secure?: a plain-English overview for non-technical readers
- MCP Server Set-Up: enable the key and connect Claude, Claude Code, ChatGPT via Codex, Cursor, or any client
- MCP Tools Reference: every tool, its inputs, scope, and gate
- How AI Agent Writes Are Protected: the five server-enforced layers
- AI Agent Prompts for Order Management: what to ask, by role
- Headless Order Management: the engine keeps running, your agents become the interface
- Autonomous Fulfillment Agent: receiving, tracking, and a morning report on a schedule, unattended
- AI Agents for 3PL Clients: per-client read-only keys and onboarding by link
REST API: Order Management
- Authentication: standard REST Bearer token; see the Authentication docs. Create keys at Tools > Admin API in your InfiPlex admin, or contact InfiPlex Support for your API URL. API access requires a Growth or Enterprise package.
- Pull Orders: GET Order Search. Use
date_created_greater_equal_thanto pull only orders since your last check, and check for duplicates before inserting. - Explain Routing: GET Order Warehouse Routing Explanation returns the step-by-step record of how each order line was routed to a warehouse; see multi-warehouse order routing.
- Send Tracking: POST Order Tracking Create. InfiPlex forwards the tracking to the order's marketplace automatically.
- Send Inventory: POST Inventory Set Bulk updates levels across your SKUs.
- Shop Log: GET Log Types and GET Log Search read the record InfiPlex writes for every channel call and routing pass.
- API Support: included with the connection; email support answers developer questions on the API itself.
REST API: Pricing
Each marketplace with pricing enabled carries a Pricing Multiplier, applied to the system price to produce what is sent to that marketplace. A price change queues updates to every marketplace with pricing on.
- Get Pricing: GET Price Get
- Set Price: PUT Price Set
REST API: Warehouses
- Get: GET Warehouse Get
- Update: PUT Warehouse Set
- Create: POST Warehouse Create
- Search: GET Warehouse Search
