How to pass parameter to the visual workflow in Salesforce?

Hi Debbie,

You can pass variables using the standard HTTP URL parameters. So from the lead page you can have a link to launch a flow and pass the leadID as the following nax.salesforce.com/flow/myLeadFlow?vaLeadID={!ID}

where vaLeadID is the unique name of the variable in flow.

<apex:page>
<flow:interview name="MyFlow">
<apex:param name="var1" value="Value1"/>
</flow:interview>
</apex:page>
