What should the CELERY BROKER URL be when using Amazon SQS?

I am using Celery with Amazon SQS. I set all settings about Celery and Amazon SQS in my django server. But i couldn't perform function.delay() with SQS. My Celery Broker URL is: CELERY_BROKER_URL = "sqs://{aws_access_key}:{aws_secret_key}@".format( aws_access_key=AWS_ACCESS_KEY_ID, aws_secret_key=AWS_SECRET_ACCESS_KEY ) Is it enough for me or do i missing a point? Because tasks is working properly without .delay() but with .delay() the function in tasks is not working.
