# Custom resource provider defined name-value pairs to send with response.
custom_resource_data = {
'IndexName': 'opensearch-index-name'
}
response.respond(
status=CfResponse.CfResponseStatus.SUCCESS,
data=custom_resource_data,
resource_id=custom_resource_id
)
Initiate FAILED response if custom resource provisioning failed.
response.respond(
status=CfResponse.CfResponseStatus.FAILED,
status_reason=error_message
)
