[DMP 2026]: Collab | Enhancements

[Pragya279]

Ticket Contents

Task 1:

Description

This feature enables community users to delete their data from MOSIP Collab directly from the Collab Landing Page, providing an alternative and easily accessible mechanism outside of email links.

The solution ensures user control, improved experience, and compliance with privacy regulations, while also triggering secure deletion of associated UIN and personal data upon successful deletion.

Goals & Mid-Point Milestone

Overall Goals

• Add "Delete My Data" option on Collab Landing Page
• Capture user input (email, reason, consent)
• Validate delete requests against backend systems
• Implement data deletion workflow (UIN + associated data)
• Handle already deleted users gracefully
• Prevent future communications to deleted users
• Maintain audit logs and analytics for deleted actions
• Ensure compliance with data privacy and consent requirements

Mid-Point Milestone

• Add "Delete My Data" CTA on Collab Landing Page
• Redirect flow to delete form
• Form with required fields (email, reason, consent)
• Backend API to process delete requests
• Validation for already deleted users
• Success and error messaging
• Basic tracking of deleted requests

Setup/Installation

No response

Expected Outcome

The final implementation will provide a simple, accessible, and compliant deletion experience via the landing page:

• Users visiting the Collab Landing Page can easily find and click on the “deletion” option

• Clicking the option redirects them to an deletion form where they:

  • Enter their UIN
  • Select a reason for deletion
  • Provide optional feedback
  • Confirm consent

• Upon submission:

  • The system validates whether UIN is already deleted

  • If not:

    • The system deletes the associated UIN and all linked personal data
    • Marks the UIN as deleted
    • Displays a success message

  • If already deleted:

    • Displays a message indicating no further action is required

• The system ensures that no further notifications are sent to deleted users

• The system ensured that no actions performed such as authentication/ download etc using this UIN

• All delete actions are logged for audit and analytics purposes

This feature improves discoverability, user autonomy, and trust, while ensuring regulatory compliance.

Task 2:

Problem Statement:

After completing the self-registration process and successful UIN generation, users do not have a clear next step or call-to-action on the screen. This can lead to confusion about what they should do next or how to proceed within the system.

Proposed solution:

We should add a clear, visible button on the success screen shown after UIN generation in the self-registration flow. This button should guide the user to the next logical step which is to go to the landing page of MOSIP Collab Environment, ensuring a smooth and guided user experience.

Additional context

The goal is to improve user experience by reducing uncertainty after successful UIN generation and ensuring users are clearly guided to the next step in the self-registration journey.

Basic Flow Description

1. Self-registration completion:

The user completes self-registration process and receives a successful UIN generation confirmation message on the screen.

2. Call-to-action (CTA) display:

On the success screen, a clear and prominent CTA button is displayed immediately after confirmation. This CTA is intended to guide the user to the next step instead of leaving them at a dead-end screen.

3. Redirect to MOSIP Collab landing page for testing:

When the user clicks the CTA, they are redirected back to the MOSIP Collab environment landing page. From there, they can proceed to test and validate the UIN they have just received using the available authentication and verification flows.

Task 3:

Problem Statement:

Email Content Link Hyperlink Fixes

Title:

Ensure links in emails sent from the Collaboration environment are rendered as clickable hyperlinks

As a recipient of emails sent from the Collaboration (Collab) environment,
I want URLs and links included in the email content to be displayed as clickable hyperlinks,
So that I can easily navigate to the referenced pages without having to manually copy and paste the URLs.

Acceptance Criteria:

1. All valid URLs included in the email body are rendered as clickable hyperlinks.
2. Hyperlinks are correctly displayed across supported email clients.
3. Clicking a hyperlink opens the intended destination URL.
4. Plain text URLs are automatically converted into hyperlinks where applicable.
5. Existing email formatting and content remain unaffected after the change.
6. Hyperlinks are tested and verified in emails generated from the Collab environment.

Hey @Pragya279, I noticed the ticket mentions secure handling of email input, but I didn’t see any verification step to ensure the person owns the email they enter. Without that (like an OTP), someone could request deletion of another person’s UIN. Is verifying ownership part of the scope, or handled differently?

[A-Chronicle]

hello @Pragya279 !
Hi! I'd like to be assigned to this issue. I've analyzed the requirements and here's my implementation strategy:

Comprehensive Approach

Phase 1: Frontend Implementation

• Add "Unsubscribe" button to landing page (prominent placement)
• Create unsubscribe form component with:
  • Email input field (validation)
  • Reason dropdown (required reasons)
  • Optional feedback textarea
  • Consent checkbox (mandatory)
• Form validation & error handling

Phase 2: Backend Integration

• Create /unsubscribe API endpoint with:
  • Email validation & format checking
  • Check if email already unsubscribed
  • Retrieve associated UIN(s)
  • Delete UIN and linked personal data
  • Store unsubscribe record (email, reason, timestamp)
• Implement blocklist to prevent future emails

Phase 3: User Experience & Messaging

• Conditional success messages:
  • "Already unsubscribed" → for existing entries
  • "Successfully unsubscribed & data deleted" → for new requests
• Email notification to user confirming unsubscribe
• Loading states & accessibility considerations

Phase 4: Compliance & Monitoring

• Comprehensive audit logging for all unsubscribe requests
• Analytics tracking for reporting & trend analysis
• Data protection compliance validation
• Rate limiting to prevent abuse

Testing Plan

• Unit tests for validation logic
• Integration tests for API endpoints
• E2E tests for user flow
• GDPR/Data protection compliance checks

Deliverables

• Clean, documented code
• Comprehensive PR with clear commit messages
• Test coverage report
• Documentation for future maintainers

I'm committed to delivering a production-ready implementation that meets all compliance requirements. Looking forward to contributing! 🚀

Hi @Pragya279 and @anushasunkada! I am interested in contributing to this
issue for DMP 2026.
What I've explored so far:

• Reviewed the Figma designs (Collab_Revamp) - the unsubscribe flow has
  clear states: form view, success screen, and "already unsubscribed" screen
• Visited collab.mosip.net to understand the current landing page structure
• Searched across the MOSIP GitHub org for the Collab Landing Page repo -
  it seems to be private/not yet public
  My implementation plan for the frontend:
• Add a visible "Unsubscribe" CTA button on the landing page (matching Figma)
• Build the unsubscribe form with:
  • Email ID (mandatory)
  • Reason dropdown with "Others" → conditional free-text field
  • Additional comments (optional)
  • Consent checkbox with UIN deletion warning
• Handle both success and "already unsubscribed" states as shown in the UXD
• Initial approach: custom form page (can also redirect to Google Form as fallback)
  Could you share access to the Collab Landing Page repository so I can
  start contributing? Happy to begin immediately.
  Looking forward to this!

[sachin9919]

Hi @Pragya279,

I’ve reviewed the ticket and the discussion above. I understand that the Collab Landing Page repository is currently not publicly accessible.

I’d like to contribute to this feature, especially starting with the frontend part (Unsubscribe CTA and redirect/form flow).

Could you please confirm:

1. Which repository this feature should be implemented in?
2. Or if access can be provided to the Collab Landing Page codebase?

In the meantime, I can start with a basic implementation (UI + form flow) aligned with the Figma design, if that works.

Looking forward to your guidance. Thanks!

[CodeBySayak]

Hi @Pragya279 @anushasunkada,
I’d like to work on the Unsubscribe feature for the Collab Landing Page.
I went through the ticket and my understanding is that we need to add a visible unsubscribe option on the landing page, redirect users to a form (Google Form or custom page), and handle validation + backend processing (including already unsubscribed users and data deletion flow). I can start with the landing page changes (CTA + redirect), then move to form handling and API integration. I’ll also make sure edge cases like duplicate requests and proper success/error messaging are handled cleanly. Could you please confirm:

• Whether we should use a Google Form initially or directly build a custom form?
• If there’s an existing API for unsubscribe validation, or should that be implemented as part of this task?
  Happy to start with a small PR for the UI part first.
  Thanks!

[siddhiguptas]

Hi @Pragya279 @anushasunkada , I’d like to work on this for DMP 2026. I have prior experience building full-stack applications with a focus on clean backend workflows and user-facing flows, so this problem aligns well with my interests.

I’ll start by preparing a structured plan with phases covering:

• Collab landing page update with Unsubscribe CTA (as per Figma)
• Form flow for collecting user inputs (email, reason, consent) with proper validation
• Backend unsubscribe API (status check, suppression handling, logging)
• UIN lookup and secure data deletion workflow (async + idempotent)
• Handling edge cases (already unsubscribed users, multiple UINs, repeat requests)

I’ve also put together a detailed phase-wise approach and architecture here:

https://www.notion.so/Collab-Unsubscribe-UIN-Data-Deletion-Approach-34e37e8ca27c80d0af9ee78f16ae21b1

It covers the full flow from user interaction to backend processing and data deletion, including API design, data handling, and failure scenarios.

I’ll begin with a minimal working prototype (landing page + unsubscribe flow + mock backend) as the first step, and then iterate towards full integration.

Would appreciate feedback on the approach or if there’s any specific part you’d like me to prioritize first.

[Sagarsingh9528]

Hi @Pragya279 @anushasunkada , I came across this DMP 2026 project and I’m really interested in working on the Unsubscribe Feature for the Collab Landing Page.

I have experience in frontend and backend development using React, JavaScript, Node.js, and APIs. My approach would be to first implement the Unsubscribe CTA on the landing page, then build a responsive form with validation, and connect it to a backend API that handles unsubscribe logic, including email validation, data deletion workflow, and maintaining a suppression list.

I also plan to ensure proper user feedback, error handling, and basic analytics logging for unsubscribe actions.

I would love the opportunity to contribute to this project and learn while building a real-world feature. Please let me know how I can get started.

Thank you!

Hi @Pragya279 @anushasunkada, could you share the Collab Landing Page repository so I can start contributing? I'd like to begin with the unsubscribe feature frontend

[Prasoon52]

Hi @Pragya279 and @anushasunkada,

I’ve reviewed the ticket requirements and the Figma mockups for the Collab Unsubscribe flow. I would love to take this on!

Based on the acceptance criteria and the designs, here is my phased implementation plan:

Phase 1: Setup & Landing Page Integration
CTA Placement: Add the lightweight "Unsubscribe" link to the Collab Landing Page footer (matching the Figma layout) to ensure it's easily discoverable without cluttering the main UI.

Routing: Set up the new /unsubscribe route to house the dedicated form.

Phase 2: Frontend Form Development
UI Construction: Build the centered, card-based form matching the exact typography and spacing of the Figma designs.

Dynamic Fields: Implement the mandatory Email input, Reason dropdown, and the mandatory Consent checkbox with the UIN deletion warning.

Conditional Logic: Add the logic where selecting "Others" in the dropdown dynamically makes the "Additional Comments" text area a mandatory "Please specify" field.

Phase 3: State Management & UI Views
Client Validation: Ensure the submit button remains disabled until all mandatory fields (including correct email formatting) are validated.

View Swapping: Implement the three distinct visual states based on API responses:

Default: The Unsubscribe Form.

Success: The green checkmark card ("Unsubscription Successful" + data deletion confirmation).

Already Unsubscribed: The orange info card ("Already Unsubscribed").

Phase 4: Backend API & Data Workflow
Endpoint Creation: Set up the POST /api/unsubscribe endpoint to receive the form payload.

Status Check (AC4/AC5): Query the backend to check if the email is already on the suppression list.

Deletion Trigger (AC6/AC7): If active, execute the workflow to locate and securely delete the associated UIN(s) and demographic data.

Logging (AC11/AC12): Add the email to the suppression list and log the unsubscribe event (reason, timestamp) for MOSIP's analytics.

Phase 5: Testing & QA
E2E Testing: Verify the complete flow from the landing page click to the database deletion.

Edge Cases: Ensure duplicate submissions are handled gracefully without triggering secondary deletion loops.

Responsive Design: Guarantee the form and success cards render perfectly on mobile devices.
