    for integration in integrations:
        req_templates = integration.get('requestTemplates') or {}
        res_templates = integration.get('responseTemplates') or {}
        success_code = integration.get('successCode') or '200'
        client_error_code = integration.get('clientErrorCode') or '400'
        server_error_code = integration.get('serverErrorCode') or '500'
        
        client.put_integration(
            restApiId=api_id,
            resourceId=resource_id,
            httpMethod=method['httpMethod'],
            integrationHttpMethod=method.get('integrationHttpMethod') or method['httpMethod'],
            type=integration['type'],
            uri=integration['uri'],
            requestTemplates=req_templates
        )
        response_configs = [
            {'pattern': '^2.*', 'code': success_code, 'res_templates': res_templates},
            {'pattern': '^4.*', 'code': client_error_code, 'res_templates': {}},
            {'pattern': '^5.*', 'code': server_error_code, 'res_templates': {}}
