Implement Email Verification for Customers & Sellers: A Comprehensive Guide

In today's digital age, email verification has become an essential security measure for both customers and sellers. It helps prevent spam accounts, ensures the authenticity of users, and provides a secure way to access features and services. In this article, we will guide you through the implementation of email verification for customers and sellers, covering the necessary steps, acceptance criteria, and testing procedures.

Why Email Verification is Important

Email verification is crucial for several reasons:

  • Prevents Spam Accounts: By verifying email addresses, you can prevent spammers from creating fake accounts and sending unwanted emails.
  • Ensures Authenticity: Email verification helps ensure that users are who they claim to be, reducing the risk of identity theft and fraud.
  • Provides Secure Access: Verified email addresses provide a secure way to access features and services, reducing the risk of unauthorized access.

To implement email verification for customers and sellers, follow these steps:

Step 1: Install Nodemailer

The first step is to install Nodemailer, a popular email sending library for Node.js. Run the following command in your terminal:

npm install nodemailer

Step 2: Generate Email Verification Tokens

Next, generate email verification tokens using a UUID-based approach. This will ensure that each token is unique and can be verified securely.

Step 3: Store Verification Tokens in DynamoDB

Store the verification tokens in DynamoDB with an expiration time. This will ensure that tokens are valid for a limited time and can be revoked if necessary.

Step 4: Send Verification Email

Send a verification email to the user containing a unique verification link. This link should be generated using the verification token and should be valid for a limited time.

Step 5: Implement API Route to Verify Email Tokens

Implement an API route to verify email tokens. This route should accept the verification token as a parameter and return a success or error response.

Step 6: Restrict Access to Certain Features

Restrict access to certain features until the email is verified. This will ensure that users cannot access protected features until they have verified their email address.

To ensure that the email verification system is working correctly, follow these acceptance criteria:

  • Customers & Sellers Receive a Verification Email Upon Signup: Verify that customers and sellers receive a verification email upon signing up.
  • Clicking the Verification Link Marks the Email as Verified: Verify that clicking the verification link marks the email as verified.
  • Unverified Users Cannot Access Protected Features: Verify that unverified users cannot access protected features.
  • Expired Tokens Result in an Error Response: Verify that expired tokens result in an error response.

To ensure that the email verification system is working correctly, follow these testing steps:

Test in Test Environment

  1. Signup & Receive Verification Email:
    • Sign up a new user (customer/seller).
    • Verify that an email is sent with a verification link.
  2. Verify Email:
    • Click the link and confirm response: message: "Email verified successfully".
  3. Attempt Access Before Verification:
    • Try accessing a protected route → Expect 403 Forbidden.
  4. Attempt Access After Verification:
    • Verify email and retry → Expect Access granted.

Test in Production Environment

  1. Deploy Changes to Production (main Branch):
  2. Repeat Email Verification Tests Using Production API:
  3. Ensure All Responses Match Expected Results:

By following these implementation steps, acceptance criteria, and testing procedures, you can ensure that your email verification system is working correctly and providing a secure way to access features and services for customers and sellers.
