<dependency>

SlackComponent
The SlackComponent with XML must be configured as a Spring or Blueprint bean that contains the incoming webhook url for the integration as a parameter.
<bean id="slack" class="org.apache.camel.component.slack.SlackComponent">
    <property name="webhookUrl" value="https://hooks.slack.com/services/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"/>
</bean>For Java you can configure this using Java code.
Example
A CamelContext with Blueprint could be as:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" default-activation="lazy">
    <bean id="slack" class="org.apache.camel.component.slack.SlackComponent">
        <property name="webhookUrl" value="https://hooks.slack.com/services/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"/>
    </bean>
    <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="direct:test"/>
            <to uri="slack:#channel?iconEmoji=:camel:&username=CamelTest"/>
        </route>
