Perguntas frequentes
What information do you need to start?
API documentation or Postman collection, your Android project files, API base URL, authentication method, and which screens should display the data. The more detail you share, the faster I can deliver.
Do you work with APIs that require authentication?
Yes — JWT, OAuth2, API keys, Basic Auth, and session-based auth are all supported. Secure credential storage using Android Keystore is included in Standard and Premium packages.
My API is not documented properly. Can you still help?
Yes, send me what you have — even a rough description of request/response structure is enough to get started. I can also help you reverse-engineer endpoints from a working web app if needed.
Can you integrate multiple APIs in one order?
The Basic package covers 1 API. For multiple APIs or a full backend integration, the Standard or Premium packages are the right fit. You can also message me for a custom quote.
Will you use Retrofit, Volley, or something else?
I default to Retrofit + OkHttp with Coroutines, which is the industry standard for Android. If your project already uses Volley or Ktor, I can work with that too.
