Why Is API Integration Sometimes Expensive?
Advanced integrations often involve complex logic, large data volumes, testing environments, and security protocols. Developers also need to handle edge cases, fallback handling, token refresh mechanisms, and long-term maintainability. The investment ensures business continuity and efficiency at scale.

Look for API experience relevant to your tech stack (Node.js, PHP, Python, Java), familiarity with platforms you’re connecting (ERP, CRM, CMS, payment), and clear communication. Toby allows you to review case studies, past work, and even schedule intro calls with shortlisted providers.
Why Hire a Professional API Developer?
DIY integration can result in data mismatches, security vulnerabilities, or downtime. A professional ensures code consistency, secure handling of credentials, proper versioning, and clean documentation—critical for future upgrades and team collaboration.
What is API integration in simple terms?
It’s the process of connecting two or more software systems so they can automatically share data and functions—reducing manual steps and improving efficiency.
