## Configuration Requirements

### Required for Entra VerifiedID
```bash

ENTRA_CLIENT_ID=your-client-id
ENTRA_CLIENT_SECRET=your-client-secret
ENTRA_CREDENTIAL_MANIFEST_ID=your-manifest-id
```

EIDAS_API_KEY=your-eidas-api-key
# Plus all Entra VerifiedID variables above
```

### Required for Logic Apps

AZURE_LOGIC_APPS_WORKFLOW_URL=https://your-logic-app.azurewebsites.net
# Either:
AZURE_LOGIC_APPS_ACCESS_KEY=your-access-key
# Or:
AZURE_LOGIC_APPS_MANAGED_IDENTITY_CLIENT_ID=your-managed-identity-client-id
```

## Testing

### Manual Testing
1. Set up Azure AD app registration
2. Create credential manifest in Azure Portal
3. Configure environment variables
4. Test credential issuance: `POST /vc/issue/entra`
5. Test credential verification: `POST /vc/verify/entra`
6. Test eIDAS bridge: `POST /eidas/verify-and-issue`

### Integration Testing
- Unit tests for EntraVerifiedIDClient
- Unit tests for AzureLogicAppsClient
- Unit tests for EIDASToEntraBridge
- Integration tests for identity service endpoints

## Security Considerations

1. **Client Secrets**: Store in Azure Key Vault or similar
2. **Access Tokens**: Automatically cached and refreshed
3. **Managed Identity**: Prefer over client secrets when possible
4. **Certificate Validation**: Full chain validation for eIDAS
5. **Network Security**: Use private endpoints when available

## Next Steps

1. Add Azure Key Vault integration for secret management
2. Add comprehensive integration tests
3. Add monitoring and alerting for Entra VerifiedID operations
4. Add retry logic with exponential backoff
5. Add circuit breaker pattern for external service calls
