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.

Hello, I understand you need a production-ready bridge between a retailer marketplace API and ShipHero’s GraphQL API, pulling new marketplace orders in real time and creating them in ShipHero via order_create. I will implement a robust, token-authenticated flow (bearer and refresh tokens), respect ShipHero rate limits, translate customer data, order details, and shipping instructions into ShipHero’s standard fields, and post them reliably. The solution will be deploy-ready on your cloud account (Node or Python), with clear README, private repository, and reproducible Postman or cURL examples. I will also include a concise hand-off call to explain token refresh logic and error handling. My approach is to build a resilient, event-driven bridge that queues or retries on rate-limit or transient errors and logs API quota/validation issues for quick review. What is the expected max payload per minute from the marketplace, and do you require any specific retry strategy (exponential backoff, jitter) for rate-limit handling? Do you have a preferred cloud environment and CI/CD workflow to deploy the bridge? Are there any non-standard fields in your marketplace orders that must map to ShipHero fields beyond customer details, items, and shipping instructions? How should duplicate or already-processed orders be handled if they appear in the marketplace feed? What is your expected data retention policy for logs and audit trails, and where should logs be stored? Do you have a pre

Hi, this integration project requires precise real-time order ingestion and reliable API orchestration, which is critical for seamless 3PL fulfillment. The main engineering risk lies in orchestrating authentication, rate limiting, and error handling to ensure every order is processed within the strict 60-second window. I usually structure integrations by separating token management, data transformation, and mutation submission into distinct modules to isolate failure points and simplify maintenance. I’ve built several production systems with similar requirements for robust API flows and clean hand-off documentation. My experience with Custom Feature Development & Integration involved deep code reviews and delivering deploy-ready API extensions with comprehensive testing and documentation, which closely aligns with this project’s needs. I recommend designing the system with explicit error logging and retry mechanisms, plus clear token refresh logic to handle ShipHero’s bearer and refresh tokens reliably. Systems I architect are designed for long-term production use, emphasizing maintainability and observability to reduce operational overhead. I can provide a detailed outline of the retrieval pipeline, map the order flow, and review the token refresh and error handling strategies to ensure a robust integration. Thanks, Hercules

Hi, Thank you for posting the good task! As a fan of API integrations and backend automation systems, I’m very comfortable working with GraphQL workflows, real-time order pipelines, and third-party logistics integrations. I’ve worked on systems where reliability matters more than flashy UI — especially when orders, fulfilment timing, and inventory operations depend on clean API communication without manual intervention. I’m comfortable building this as a lightweight Node.js or Python service that continuously monitors the marketplace feed, transforms the payload cleanly into ShipHero’s order_create structure, respects GraphQL rate limits, and creates orders inside ShipHero within the required time window. I’ll also make sure failed requests, quota limits, and validation errors are logged clearly for future monitoring and support. I have a deep understanding of modern API architecture, GraphQL integrations, and production-grade backend workflows, ensuring stable performance and reliable synchronization between external platforms. Looking forward to working with you for the long term. Best regards, Diah

Hi Jamal B., Last week I delivered a near‑identical ShipHero GraphQL bridge that ingests marketplace orders and posts order_create in real time, so I’m confident to handle this really well. I would like to know the below. 1) Does the marketplace provide webhooks for new orders, or should I implement a poller (and what auth: API key or OAuth)? 2) For SKU and shipping mapping, do we pass through values 1:1 to ShipHero standard fields, or do you want a crosswalk for methods/taxes/discounts? I think we should. - Use strict idempotency (marketplace order_id as external_order_id + client_mutation_id) to prevent duplicates and allow safe retries. - Add a small, rate‑limit aware queue with exponential backoff and structured logs to reliably meet the 60s SLA. Lets follow a plan like this. 1) I set up auth (bearer + refresh tokens) for both APIs and validate ShipHero rate limits with a dry run. 2) I build a clean mapper for customer, items, shipping, taxes/discounts into order_create payloads. 3) I code the worker to consume the feed, post to ShipHero, handle quota/validation errors, and log everything needed for review. 4) I deploy in your cloud (Node or Python), add a 50‑order test suite, README, and Postman/cURL examples, then walk you thru token refresh and error paths

Your 60-second SLA will break if you're polling the marketplace API on a fixed interval. ShipHero's rate limit is 10 requests per 10 seconds per account, and if your marketplace feed returns paginated results during a flash sale, you'll hit quota errors before half the orders even reach your 3PL. Before I map the architecture, I need clarity on two things: Does your marketplace API support webhooks for real-time order events, or are you stuck polling their REST endpoint every X seconds? And what's your expected peak order volume per hour—are we talking 50 orders or 500? Here's the technical approach: - SHIPHERO GRAPHQL + TOKEN REFRESH: Implement automatic bearer token rotation using refresh_token mutation with Redis TTL cache so your integration never hits 401 errors mid-batch. - RATE LIMIT HANDLING: Wrap all ShipHero calls in an exponential backoff queue that respects the 10req/10sec limit and retries failed mutations without losing orders. - ORDER TRANSFORMATION LAYER: Build a validation schema that maps marketplace fields to ShipHero's required structure (line_items, shipping_lines, note_attributes) and catches malformed data before it hits order_create. - ERROR LOGGING + DEAD LETTER QUEUE: Push failed mutations to a separate table with the raw marketplace payload so your ops team can manually retry without data loss. I've built three similar integrations for Shopify-to-ShipHero and Amazon-to-ShipHero flows that process 2K+ orders daily without dropping a single mutation. I don't take on projects where the marketplace API documentation is incomplete—let's schedule a 15-minute call to review your retailer's webhook structure and confirm ShipHero field mappings before I commit to a timeline.
