🔐 AUTHENTICATION

JWT Token Authentication

The API uses JSON Web Tokens (JWT) for secure authentication. All API endpoints (except authentication endpoints) require a valid JWT token.

1. Login and Obtain Token

curl -X POST http://yoursite.com/wp-json/care/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{
    "username": "admin",
    "password": "password"
  }'

Response Format

{
  "success": true,
  "data": {
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
    "refresh_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
    "expires_in": 3600,
    "user": {
      "id": 1,
      "user_type": "administrator",
      "full_name": "Administrator",
      "email": "admin@example.com",
      "clinic_id": null
    }
  }
}

2. Use Token in Requests

Include the JWT token in the Authorization header for all API calls:

curl -X GET http://yoursite.com/wp-json/care/v1/patients \
  -H "Authorization: Bearer YOUR_JWT_TOKEN_HERE" \
  -H "Content-Type: application/json"

3. Refresh Token

When your token expires, use the refresh token to obtain a new one:

curl -X POST http://yoursite.com/wp-json/care/v1/auth/refresh \
  -H "Content-Type: application/json" \
  -d '{"refresh_token": "YOUR_REFRESH_TOKEN_HERE"}'

Role-Based Access Control

The API supports different user roles with specific permissions:

Role	Permissions
Administrator	Full access to all endpoints and data
Clinic Admin	Manage clinic data, doctors, patients, appointments
Doctor	Access own patients, appointments, create prescriptions
Patient	View own medical data, book appointments
Receptionist	Manage appointments, basic patient information

🔧 TROUBLESHOOTING

Common Issues

Plugin Activation Problems

# Check if KiviCare base plugin is active
wp plugin list --status=active | grep kivicare

# Check PHP version compatibility
php -v  # Should be 8.1+

# Check WordPress debug logs
tail -f /wp-content/debug.log | grep care-api

# Verify composer dependencies
composer install --no-dev

API Endpoint 500 Errors

# Check file permissions
find /wp-content/plugins/kivicare-api -type f -exec chmod 644 {} \;
find /wp-content/plugins/kivicare-api -type d -exec chmod 755 {} \;

# Check memory limit
wp config get WP_MEMORY_LIMIT  # Should be 512M+

# Enable debug mode temporarily
wp config set WP_DEBUG true
wp config set CARE_API_DEBUG true

JWT Authentication Issues

# Apache - add to .htaccess
RewriteEngine On
RewriteCond %{HTTP:Authorization} ^(.+)$
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

# Or add this line:
SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1

For Nginx, add to your server configuration:

location ~ \.php$ {
    fastcgi_param HTTP_AUTHORIZATION $http_authorization;
    # ... other fastcgi params
}

Database Connection Issues

# Test database connectivity
wp db check

# Verify KiviCare tables exist
wp db query "SHOW TABLES LIKE 'kc_%'"

# Check database permissions
wp db query "SHOW GRANTS FOR CURRENT_USER()"

Performance Optimization

Enable Caching

// In wp-config.php
define('CARE_API_CACHE_TTL', 3600); // 1 hour
define('WP_CACHE', true);

Server Requirements

• PHP Memory Limit: 512MB minimum, 1GB recommended
• Max Execution Time: 60 seconds minimum
• Upload Max Size: 32MB minimum for file uploads
• Database: Ensure proper indexing on KiviCare tables
