[officialbinalhassan-boop]

“Ka haɗa Data Application tare da User Login da API integration wallet” yana nufin gina application (misali web app ko mobile app) wanda:

1. Yana da database (data storage)

2. Yana da user login / authentication

3. Yana iya haɗuwa da API na wallet domin biyan kuɗi ko karɓar kuɗi.

Zan bayyana tsarin yadda ake yi a matakai.

1. Tsarin Architecture na Application

A yawancin apps tsarin yana kasancewa kamar haka:

Frontend (UI)

Mobile app ko website

React, Flutter, HTML/CSS/JS

Backend (Server)

Yana sarrafa login da API calls

Node.js / Django / Laravel / Spring

Database

Ajiye bayanan user

MySQL / PostgreSQL / MongoDB

External API (Wallet)

Paystack

Flutterwave

Stripe

Crypto wallet APIs

---

2. User Login System (Authentication)

User login yana tabbatar da cewa mutum ɗaya kawai yana shiga account ɗinsa.

Basic Flow

1. User yayi Sign Up

2. System ya store email + password (encrypted) a database

3. User yayi Login

4. Server ya tabbatar da bayanan

5. Ana ba user token (JWT)

Example Database Table

id name email password_hash

1 Ali ali@gmail.com encrypted

Example Login API

POST /api/login

{
"email": "user@gmail.com",
"password": "123456"
}

Server zai dawo:

{
"token": "eyJhbGciOiJIUzI1NiIsInR5..."
}

---

3. Data Application (Database Integration)

Database yana adana:

user accounts

wallet balance

transactions

history

Example Tables

Users Table

id name email

Wallet Table

user_id balance

Transactions Table

| id | user_id | amount | status |

---

4. API Wallet Integration

Wallet API yana ba app damar:

add money

withdraw money

check balance

make payment

Example Wallet API Request

POST /api/wallet/deposit

Request:

{
"user_id": 1,
"amount": 1000
