Open New Saving Account - Backend Title: Backend API for Opening a New Saving Account

[suryaravikumar-space]

Description:

As a developer, I need to implement a backend API that allows users to open new saving accounts so that the system can securely manage and store account details.

Acceptance Criteria:

API Endpoint:

Implement a POST endpoint /api/accounts/saving to handle the creation of new saving accounts. The endpoint should accept the following data: User ID (extracted from the authentication token) Account nickname Initial deposit amount Account type Validate the input data before processing. Account Creation:

Create a new saving account record in the database with the provided details. Calculate and store the initial balance. Store metadata such as the account creation date and account status (e.g., active). Security:

Ensure that the endpoint is protected with authentication middleware. Validate that the user has the necessary permissions to create a saving account. Response Handling:

Return a success response with the account details if the account is successfully created. Return an error response if the account creation fails (e.g., due to validation errors, insufficient permissions). Tasks:

Implement API Endpoint: Create the POST endpoint to handle account creation. Database Schema: Define and update the database schema for saving accounts. Validation: Implement input validation for the account creation data. Authentication: Protect the endpoint with authentication middleware. Testing: Write unit and integration tests to ensure the endpoint works as expected. Flow Diagram to Integrate Frontend and Backend Here’s a flow diagram illustrating how the frontend and backend components interact for the "Open New Saving Account" feature:

The user navigates to the saving account dashboard and clicks on the option to open a new account. The user fills out the form with necessary details like the account nickname, initial deposit, and account type. Form Submission:

The frontend performs client-side validation. If the form is valid, the data is sent to the backend via a POST request to /api/accounts/saving. Backend Processing:

The backend API validates the input data and checks the user's authentication and permissions. If the data is valid, a new saving account is created in the database. The backend returns a success response with the account details if the operation is successful, or an error response if something goes wrong. Feedback to User:

The frontend handles the response from the backend. On success, the user is redirected to the saving account dashboard with a confirmation message. On failure, an error message is displayed, and the user can retry the operation. This flow ensures a seamless interaction between the frontend and backend, providing users with a smooth experience when opening new saving accounts.
