I will develop custom api integration, webhooks, and rest apis


About this gig
Are you looking to connect third-party platforms, automate complex data pipelines, or set up custom API endpoints?
As a Senior Automation Engineer and Software Architect with 8+ years of enterprise experience, I design robust, production-grade API integrations, webhook pipelines, and agentic workflows using Python, Node.js, and n8n orchestration.
What I Offer:
Custom REST & GraphQL API Integration: Secure two-way syncs between platforms.
Third-Party Platform Connectors: Integrate Stripe, HubSpot, Plaid, CRMs, and payment gateways.
Webhook & Automation Architecture: High-performance event handlers and payload transformation.
Advanced Orchestration & Agentic Logic: Multi-agent systems, workflow automation using n8n orchestration, and custom LangGraph expertise.
Authentication & Security: OAuth 2.0, API keys, JWT, and secret management.
Whether you need a quick endpoint bug fix or a full multi-API enterprise pipeline, I deliver clean, well-documented code with built-in error handling.
Please message me before placing an order to review your API documentation and project scope!

FAQ
What do you need to get started on my API integration?
I will need links to your API documentation and sandbox or API keys/credentials for the services being connected. We can also coordinate secure access via environment variables.
Do you integrate payment gateways like Stripe or Plaid?
Yes, I build secure integrations for Stripe, Plaid, PayPal, and custom payment processors, complete with webhook listeners for real-time transaction updates.
Can you build custom middleware or backend webhooks?
Custom Python and Node.js backend endpoints, serverless functions, and n8n automation pipelines are fully supported for complex data transformations.
Do you support custom webhook listeners and workflow orchestration?
Yes, I build custom Python/Node.js backend scripts, serverless handlers, and n8n orchestration pipelines to process complex payload logic.
What do you need to get started on my API integration?
I will need API documentation links and temporary sandbox credentials or API keys. We can coordinate secure configuration via environment variables.
How will optimized API integrations impact my operational efficiency?
Automated API integrations eliminate manual data entry, prevent broken webhook triggers, reduce payload handling errors, and ensure real-time synchronization across your tech stack.
