<DIV>The response to the challenge request needs to go back to RabbitHub, which
is what you appear to be doing; there should be something in the RabbitMQ log
that provides more information as to why this is failing. Possibly your UTF-8
encoding is changing the value, so the sent and received tokens do not match,
although an HTTP 500 tends too imply something a bit more serious... possibly
the 3.1.5 version of the plugin is not 100% compatible with RabbitMQ 3.2.1...
but anything liek this will be evident from the RabbitMQ log.<BR><BR></DIV>For
my testing I just tend to use the following trivial piece of Ruby Sinatra code,
which starts up a web server on port 4567. As you can see, the GET just responds
by sending back the challenge token. The POST method just displays the received
message and will return an empty response body.<BR><BR>require
'sinatra'<BR><BR>get '/sub2' do<BR> puts "Received
#{params}"<BR> puts "Responding to challenge
request..."<BR> params[:"hub.challenge"]<BR>end<BR><BR>post '/sub2'
do<BR> puts "Received message: #{params} "<BR>end<BR><BR><BR></DIV>

<DIV dir=ltr>I probably would have just returned it as a string without doing
the UTF-8 encoding, but the the HTTP 500 error is interesting. Check the
RabbitMQ log for additional information.<BR>

<P dir=ltr>That's correct. As per the documentation you can also specify a
duration for the subscription (after which it will be expired), etc.</P>
<P dir=ltr>Just be sure to note that the initial challenge is a GET; messages
are then forwarded to the URL using POST.</P>

<DIV>Lijo,<BR><BR></DIV>The error indicates that your web server at <A
href="http://rabbitmq.citrus.com" target=_blank>rabbitmq.citrus.com</A> did
not respond correctly to the initial challenge request. When a subscription
is requested, RabbitHub sends a challenge request (HTTP GET) to the
specified URL. The challenge request sends a token and the web server is
expected to respond to the challenge request by sending back the same token
in the response body. Assuming this process completes successfully the
subscription will be activated. Once the subscription has been activated,
RabbitHub will send to the subscription URL any messages matching the
subscription (note that messages are sent using HTTP POST, not
GET).<BR><BR></DIV>Brett<BR><BR></DIV>
