FAQ
Can you fix my existing API instead of building a new one?
Yes. I can troubleshoot and fix REST APIs, Stripe API, Wix API, PHP applications, webhooks, authentication errors, timeouts, JSON issues, and third-party API integrations.
Which APIs and platforms do you work with?
I work with REST APIs, Stripe, Wix API (Velo), PayPal, Shopify, WooCommerce, custom PHP APIs, webhooks, OAuth, and most third-party APIs with proper documentation.
Can you build a custom API from scratch?
Yes. I identify and fix API errors, optimize response times, improve security, resolve webhook failures, and ensure your integration works reliably.
Will my API keys and data remain secure?
Yes. Your API credentials and project data are handled securely and kept confidential. I follow industry best practices for authentication and secure API integration.
