Posting HTTP parameters with Mule using polling

First time using Mule. I have the flow listed below, which is trying to post parameters to a URL every 15 seconds.

I gather that the URL parameters have to be defined as a payload, like

Mule ESB - How to call a API via HTTP POST method (sending parameters along)

<set-payload value="#[['xxx':'yyy']]"/>

but I can't find out where to place this, when using a poll element as below. The error I get with it in it's current position is

Invalid content was found starting with element 'poll'.

I've tried before the poll, inside it and inside http:outbound-endpoint. Any ideas?

Thanks Oliver

You need to set the payload before the outbound-endpoint. However the poll only excepts one message processor so they need to be shoe-horned using processor-chain or a sub-flow or similar:

<poll doc:name="Poll">
            <fixed-frequency-scheduler frequency="15"
                timeUnit="SECONDS" />
            <processor-chain>
                <set-payload value="#[['xxx':'yyy']]" />
                <http:outbound-endpoint exchange-pattern="request-response"
                    method="POST" address="http://myurl.com" doc:name="HTTP"
                    transformer-refs="Message_Properties">
                </http:outbound-endpoint>
            </processor-chain>
        </poll>
