💻 Implementation Checklist

Server-Side ✅

  • Extract card from bridge response
  • Handle multiple field names (official_card, card_data_uri, etc.)
  • Support nested card structures
  • Detect card format (PNG)
  • Return card_base64 to client
  • Include card_content_type
  • Track card source (abdm/provisional)

Files:

  • app/Controllers/Abha.php (lines 139, 325)
  • app/Libraries/Abdm/EAtriaBridgeConnector.php (line 810)

Client-Side ✅

  • Receive card_base64 from server
  • Convert Base64 to data URL
  • Display card image in modal
  • Show source indicator (official/provisional)
  • Provide card download link
  • Fallback message if no card

Files:

  • app/Views/partials/abha_verify_modal.php (line 224)
  • app/Views/partials/abha_create_modal.php (line 420)
  • app/Views/partials/abha_mobile_modal.php (line 230)
  • app/Views/partials/abha_patient_match_modal.php (line 233)

🚀 Quick Implementation Guide

For Frontend Developers

// Step 1: Receive card from ABHA verify response
const response = await fetch('/abha/verify', { /* ... */ });
const data = await response.json();

// Step 2: Get card data
const cardBase64 = data.card_base64;
const cardContentType = data.card_content_type || 'image/png';

// Step 3: Create displayable URL
const dataUrl = `data:${cardContentType};base64,${cardBase64}`;

// Step 4: Display in HTML
document.getElementById('abhaCardImage').src = dataUrl;

For Backend Developers

// Card data is automatically extracted by:
// 1. extractAbhaCardData($result) → returns Base64 string
// 2. resolveAbhaCardContentType($result) → returns "image/png"
// 3. resolveAbhaCardSource($result) → returns "abdm" or "provisional"

// Already implemented in:
// - Abha::verifyOtp()
// - Abha::verifyCommOtp()

🐛 Troubleshooting

Card Not Displaying?

  1. Check if card_base64 is in response
  2. Verify card_content_type is set
  3. Inspect browser console for JS errors
  4. Check CSS for display/visibility issues

Card Download Not Working?

  1. Ensure data URL is properly formatted
  2. Check browser console for errors
  3. Verify href attribute on download link
  4. Test in different browser

"Provisional Card" Warning?

  1. This is correct - bridge-generated cards show this
  2. Only official ABDM cards show no warning
  3. Both types are functional
