As a developer, I want to update the existing API to align with ABDM V3 specifications, so that the system remains compliant with the latest standards and continues to function efficiently.

Acceptance Criteria:

1. Modify existing API endpoints to match ABDM V3 structure.
2. Ensure authentication and authorization mechanisms comply with ABDM V3 (OAuth 2.0, JWT, or required method).
3. Update request/response formats as per ABDM V3 API documentation.
4. Implement error handling for new API responses and failures.
5. Validate API changes through unit and integration testing.
6. Update API documentation for the new changes.

Technical Details:

• Refactor existing API endpoints to ABDM V3 structure.
• Update data models and mappings as per V3 API contract.
• Implement security updates if required (encryption, token validation, etc.).
• Perform regression testing to prevent breaking changes.

Dependencies:

• ABDM V3 API documentation.
• Access to a test environment for API validation.
• Security guidelines for API integration.
