Garfield Daniel
About this gig
If your API isnt connecting, returning errors, or breaking your workflow, its not just a technical issue its lost time, failed transactions, and frustrated users.
I help businesses fix API issues and build reliable REST and SOAP API integrations using PHP, JSON, XML, and third-party services.
Whether youre dealing with authentication failures, webhook errors, malformed responses, or unstable connections, Ill diagnose the root cause and implement a clean, structured solution.
What I handle:
- REST API integration
- SOAP API connection
- Third-party API setup
- JSON & XML data handling
- API error debugging
- Secure authentication & token fixes
- Webhook configuration
My approach is methodical. I review documentation, test endpoints properly, validate responses, and ensure stable request/response handling before delivery.
This means fewer unexpected failures and a backend that works the way it should.
If you're unsure whats causing the issue, send me your API details and error message first. I'll review it and guide you on the best solution before you place an order.

FAQ
What do you need from me to start the API integration?
To begin, I’ll need your project details, API documentation, access credentials (like Stripe keys or Shopify tokens), and a short description of the goal you want to achieve. This helps me set up your REST API or Node.js API integration securely and efficiently.
Can you integrate multiple APIs together?
Yes! I can connect multiple platforms such as Stripe API, Shopify API, eBay API, and PHP SOAP API in one seamless system. Whether you need product sync, automated order handling, or a unified backend, I’ll make them work together perfectly.
Will my data and API keys be safe with you?
Absolutely. I use encrypted connections, sandbox testing, and follow strict data security practices. Your API keys, payment details, and user data remain 100% confidential and secure throughout the entire integration process.
What makes your API integration service different?
I specialize in custom REST API and Node.js backend development — meaning your project isn’t just connected, it’s optimized for speed, security, and scalability. I focus on reliability, clean code, and automation that grows with your business.
