Development of a WordPress plugin for integration with Diia - verification system
Main Requirements
Access Restrictions:
- The verification function is available only to users from Ukraine
- Verification by user address (Ukraine) OR "Vendor" status on the site
- Automatic determination of the right to verification upon registration
- Blocking access for users from other countries
Verification Functionality:
- Integration with Diia validation API (https://integration.diia.gov.ua/validation.html)
- Scanning QR codes from the Diia app for instant document verification
- Automatic verification of the authenticity of digital documents
- Multi-level verification system (basic → extended → premium)
Badge System:
- Automatic assignment of the "Verified Factory" badge after successful verification
- Display of verification status on supplier profiles
- Visual trust indicators for buyers
- Ability to update verification status
Technical Requirements:
- Compatibility with WordPress 5.8+
- Support for multilingualism (Ukrainian, English, German)
- Responsive design
- Secure storage of verification data
- Integration with WordPress role system (verification of "Vendor" status)
Verification Access Logic
Access Conditions:
IF (user_address == "Ukraine" OR user_role == "Vendor")
THEN show_verification_button()
ELSE hide_functionality()
System Checks:
- Geographical Check: analysis of IP address and specified address in the profile
- Status Check: verification of "Vendor" role in the WordPress system
- Double Validation: the user must meet at least one condition
Use Cases
For Ukrainian Suppliers/Vendors:
- The system automatically determines the right to verification
- The user sees the "Undergo Verification" button
- The system redirects to the Diia interface
- The user shows the QR code from the Diia app
- Upon successful verification, a badge is assigned
For Other Users:
- The verification functionality is hidden
- A message "Verification is available only for Ukrainian suppliers" is displayed
- The option to apply for "Vendor" status
Additional Features
- Multi-sharing of documents: obtaining multiple documents in one request
- Anti-bot protection: authorization through Diia without sharing personal data
- Diia.Signature: ability to electronically sign documents
- Automatic updates: periodic verification status checks
- Admin panel: management of access rights to verification
Technical Details
API Integration:
- Use of the official API integration.diia.gov.ua
- Processing of QR codes and 13-digit numbers
- Real-time validation of digital documents
- Secure storage of access tokens
Database:
- Table for storing verification statuses
- Table for user access rights

- Linking with WordPress users
Security:
- Encryption of sensitive data
- Protection against CSRF attacks

- Logging of security events
- Protection against circumvention of geographical restrictions

Hello! I wanted to clarify two points: do you have access to the account integration.diia.gov.ua (keys / sandbox), and has the "Vendor" role already been implemented on your site — for example, through WooCommerce/Dokan or a custom solution?
I have been working with WordPress for over 9 years, wrote plugins, made integrations with government and third-party APIs, set up QR scanning on the frontend, implemented secure token storage with encryption, logging, and cron tasks for periodic checks. I also have experience with multilingualism, setting up roles and access rights, as well as storing statuses in custom tables.
If there is access to the sandbox/keys of Diia and a brief description of the Vendor role implementation, I can prepare a technical plan and estimate.
