Document the API Endpoints of My Android App

@crtvecode

I see you need someone to analyze those Android app's network traffic and document the API endpoints clearly for your developers. And special attention to authentication is key, especially how tokens or sessions are managed. Many miss the nuances of refreshing tokens, which can lead to confusion for new team members, I’ll make sure to detail every step so it’s easy to follow. My approach will involve using tools like Charles Proxy and Postman to capture the traffic efficiently. I can go ahead and create a concise document alongside a ready-to-import Postman collection that includes all necessary details, making sure your team has everything they need to work without guessing. I’m ready to get started on this right away for 12500 INR, let’s make this documentation clear and actionable. Rajavel API Documentation Specialist | Android Development

I can handle this from the Android side and turn the app’s actual network behavior into documentation your developers can use without reverse-engineering it again. I’m a senior Android engineer with 9+ years of experience working with existing apps, ADB, Android Studio, API debugging, authentication flows, backend integrations, and production troubleshooting. I’ll trace the app request-by-request and document each endpoint with method, headers, params/body, sample response, error cases, and the full auth lifecycle including token creation, refresh, expiry, and how credentials are attached to requests. For delivery, I’ll provide two clean outputs: a developer-friendly API reference in Markdown/Word format and a ready-to-import Postman collection with environments, sample payloads, auth variables, and example responses. I’ll use the most reliable combination of Android Studio Network Inspector, Charles/Proxy tools, ADB/logcat, and Postman depending on how the app is configured. You can send me the build and test credentials, and I can start by mapping the authentication flow first, then cover the remaining endpoints systematically.

Hi there I can analyze your Android application and create clear, developer-friendly documentation for all relevant API endpoints, including request methods, parameters, headers, authentication, request/response formats, and error handling. I have 20 years of software development experience and can work from the Android source code or existing API traffic. My approach API Discovery — Identify all API endpoints used by the Android application and map where each endpoint is called. Request Documentation — Document HTTP methods, URLs, headers, authentication, query parameters, path parameters, and request bodies. Response Documentation — Record response structures, data types, status codes, success/error responses, and important fields. Authentication — Document login, tokens, refresh mechanisms, authorization headers, and required permissions where applicable. Workflow Mapping — Explain how endpoints work together for key app features and user flows. Final Documentation — Deliver organized API documentation in your preferred format, with examples where useful. Quick questions 1. Do you have the Android source code, APK, or both? 2. Is the backend/API documentation partially available already? 3. Do you need OpenAPI/Swagger documentation or a custom document? 4. Should the documentation include sample requests and responses? 5. Do you need the API endpoints tested as part of the documentation? Share the Android project/APK and any existing API information. Thanks

@nakabirik

Hello, I have read your project requirement description carfully! The key is turning captured Android traffic into documentation that another developer can actually reproduce, especially around authentication, refresh flows, required headers, and request/response variations. I can inspect the app traffic and map each call into a structured API reference. I’ll document endpoints, methods, headers, parameters, JSON/XML schemas, token/session behaviour, error responses, and dependencies, then build a matching Postman collection with environments and runnable examples. I’ll use Android Network Inspector/Charles/Postman as appropriate and validate the collection against the supplied test environment before handover. Can you provide the Android build and confirm whether the backend has separate staging/test endpoints? Looking forward to working with you. Muheebwa

@cheekean2012

Hi, I hope you're doing well. I understand you need someone to reverse-map the existing Android app’s backend communication and turn it into clear, developer-ready API documentation. The important part is capturing the complete request/response flow—including authentication, headers, parameters, token refresh, and session behavior—so your developers can reproduce the integration without guesswork. I will inspect the app’s network traffic using tools such as Charles Proxy, Android Studio Network Inspector, or Postman, document each endpoint with its method, URL, headers, parameters and response structure, and trace the authentication lifecycle carefully. I’ll then create a clean Markdown/Word reference document and a ready-to-import Postman collection with environment variables, sample requests, and example responses, validating the collection against the observed traffic. My focus is to deliver accurate, practical documentation that your developers can use immediately, with the API flows organized consistently and no important authentication or edge-case details overlooked. I can also provide relevant API documentation samples for review. Best.

@mariamshaikh018

Hi, clean API documentation and a Postman collection built by tracing every call your app makes to its backend. The tricky part is documenting the auth flow clearly, how tokens get issued, refreshed and attached, so a new dev doesn't have to guess. How many distinct endpoints are we roughly talking about? My team has documented and built API layers behind live production systems, a banking chatbot for JS Bank and a RAG chatbot for a diagnostics lab, so tracing traffic and writing it up clearly is familiar work. Happy to start with a small batch of endpoints as the first milestone so you can check the format first. Regards, Mariam

@abhilashr53

You need every network call your Android app makes mapped into clean reference docs and a working Postman collection — something a new dev can pick up and run with immediately. Here's my approach: I'll intercept traffic using Charles Proxy and Android Studio's Network Inspector, catalog every endpoint with full URL, method, headers, params, and response shapes, then document auth flows (token acquisition, refresh logic, header injection) explicitly. Deliverables: a structured Markdown/Google Doc reference plus a fully configured Postman collection with environment variables and example responses. I've produced this type of documentation for REST APIs across multiple mobile projects — structured, developer-first, no ambiguity. Timeline: 3-5 days depending on endpoint volume. Can you give me a rough count of how many distinct API calls the app makes, and whether auth is JWT, OAuth, or session-based?
