Maven users will need to add the following dependency to their pom.xml for this component:
<dependency>

<artifactId>camel-slack</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>306.1. URI format
To send a message to a channel.
slack:#channel[?options]
To send a direct message to a slackuser.
slack:@username[?options]

306.3. 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.
306.4. 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>
</camelContext>
