Experienced ShipHero API Developer

I need a developer who already knows their way around ShipHero’s public GraphQL API to build a production-ready bridge between a retailer marketplace API (I’ll share credentials after kickoff) and our ShipHero account. The integration’s single purpose is to pull every new marketplace order in real time and push it into ShipHero with a clean order_create mutation so our 3PL team can fulfil inside ShipHero without manual touch points. Scope of the work You’ll handle the full flow: authenticate to ShipHero with bearer and refresh tokens, respect ShipHero rate limits, fetch the marketplace feed, translate each order’s customer information, order details and shipping instructions into ShipHero’s standard fields, then post with order_create. No custom fields are needed at this stage. Deliverables • A deploy-ready integration (Node, Python or similar is fine) running on our cloud account • Source code in a private repo with clear README • Postman or cURL examples that reproduce the workflow • A short hand-off call to walk through token refresh logic and error handling Acceptance criteria The integration must create every incoming order in ShipHero within 60 seconds of availability, pass a test suite of at least 50 sample orders, and log any API quota or validation errors for review. If you have shipped live solutions with ShipHero before—especially those using order_create—let’s talk.
