Re: missing amqp-exchange on bucket-notification with AMQP endpoint

Dear Yuval!

The message format you tried to use is the standard one (the one being
emitted from boto3, or any other AWS SDK [1]).
It passes the arguments using 'x-www-form-urlencoded'. For example:

Thank you for your clarification! I've previously tried it as a
x-www-form-urlencoded-body as well, but I have failed. That it was then
working using the non-standard-parameters has lead me down the wrong road...
But I have to admit that I'm still failing to create a topic the S3-way.

I've tried it with curl, but as well with Postman.
Even if I use your example-body, Ceph keeps telling me (at least) method-not-allowed.

Is this maybe because I'm using an AWS Sig v4 to authenticate?

This is the request I'm sending out:
