FAQ
Which APIs can you integrate?
I can integrate virtually any REST API that provides documentation, including payment processors, shipping providers, CRMs, email platforms, AI services, ERP systems, and custom business APIs.
What do you need before you can start?
Please provide a brief description of your project, your existing PHP application (if applicable), API documentation or a link to it, and any API credentials (test credentials are preferred). I'll review everything before beginning work.
Can you work with existing PHP applications?
Yes. I regularly work with existing applications and can integrate new APIs, troubleshoot existing integrations, improve performance, or extend current functionality while maintaining clean, maintainable code.
Do you fix API integration problems?
Yes. If your existing API integration is returning errors, authentication is failing, data isn't syncing correctly, or webhooks aren't working as expected, I can diagnose and resolve the issue.
Can you integrate multiple APIs?
Yes. If your project requires multiple third-party services to work together, I can prepare a custom offer or you can purchase the Extra API gig extra for additional integrations.
What if I'm not sure which package I need?
Not sure which package fits your project? Send me a message before ordering. I'll review your requirements, answer your questions, recommend the best option, or create a custom offer tailored to your needs.
