[FEAT] : Implement Webhook Handling for Payment Events

[Juninhotech]

Description

Set up a webhook endpoint to handle payment events from the payment gateway provider. This will enable the system to receive real-time notifications of payment events (e.g., successful payments, subscription renewals) and update user accounts accordingly.

Acceptance Criteria

• The webhook handler returns appropriate HTTP status codes (e.g., 200 OK for successful processing, 400 Bad Request for invalid payloads) to the payment gateway provider.
• The handler includes comprehensive logging of all received payloads, processed events, and any errors encountered.

Purpose:

To ensure that user accounts are updated in real-time based on payment events, improving the accuracy and timeliness of account management.

Requirements:

1. Configure Webhook Endpoint:**

• Register and configure the webhook endpoint URL in the payment gateway provider's dashboard.

2. Implement Webhook Handler:

• Develop a webhook handler to receive and process incoming webhook payloads.
• Ensure the handler can verify the authenticity of the incoming requests (e.g., through HMAC signatures).

3. Update User Accounts:

• Update user accounts or perform necessary actions based on the data received in the webhook payloads.

4. Expected Outcome:

• A functional webhook handler that processes payment events and updates user accounts accordingly, ensuring accurate and timely account management.

Checklist:

1. Configure Webhook Endpoint URL:

• Access the payment gateway provider's dashboard.
• Register the webhook endpoint URL.
• Specify the types of events to be sent to the webhook (e.g., payment succeeded, subscription renewed).

2. Implement Webhook Handler:

• Create a secure endpoint in your backend application to receive webhook payloads.
• Implement logic to parse the incoming payloads.
• Verify the authenticity of the requests using HMAC signatures or other provided methods.
• Log incoming requests for debugging and auditing purposes.

3. Update User Accounts:

• Map the webhook data to user accounts in your database.
• Update user account statuses, balances, or subscription details based on the event type.
• Trigger relevant actions (e.g., send confirmation emails, update billing records).

4. Testing:

• Test webhook handling with sample payloads provided by the payment gateway.
• Test various scenarios such as successful payments, failed payments, and subscription renewals.
• Ensure the handler can correctly process and respond to these events.

5. Error Handling and Monitoring:

• Implement error handling to manage failed webhook deliveries or processing errors.
• Set up monitoring and alerts for webhook endpoint failures or unusual activities.
