FAQ
Do you need my API keys or account credentials?
Security is my top priority. You should never share your main account password. For the integration, you will only need to provide the API Keys (Secret/Public) or Client IDs. I will guide you on how to set these up securely in an .env file so your credentials stay protected.
Can you integrate an API that doesn't have a Node.js SDK?
Absolutely. If an official SDK isn't available, I will build a custom API Client/Service layer using Axios or the Fetch API, following the external service's REST or GraphQL documentation.
Do you provide documentation for the new endpoints?
Yes. I will update your Swagger (OpenAPI) documentation so your frontend team knows exactly what data the new integration returns and what parameters are required
