FAQ
Can you develop a custom REST API or integrate an existing API?
Yes. I can build REST API endpoints or connect your application to a third-party service. Share your technology stack and documentation so I can confirm compatibility, scope and the right package.
Which APIs and platforms can you work with?
I can help with documented payment, CRM, email, shipping and business APIs. Compatibility depends on your stack and the provider's access rules. Send the documentation before ordering so I can confirm feasibility.
What do you need before starting?
I need your goal, API documentation, technology stack, sample data and relevant project access. Where access is necessary, use temporary, limited-permission credentials. Please do not send account passwords or production secrets in your initial message.
Can you fix an API that is already failing?
Yes, after reviewing the error, relevant code and provider documentation. I will confirm whether the issue fits a package or needs a custom offer. Provider outages, missing permissions and unsupported features may require action from the API provider.
Do packages include hosting or API subscription fees?
No. Hosting, paid API plans, usage charges and provider approval fees are paid by you. Live deployment and ongoing maintenance are included only when explicitly listed in the agreed scope or custom offer.
Should I contact you before ordering?
Please message me first if you are unsure about compatibility, endpoint count or complexity. Send the API documentation and desired result, and I will confirm the scope, delivery time and suitable package or custom offer.
