Steps:

1. Add Camel Mustache dependency to your Integration Flow

<dependency>
    <groupId>org.apache.camel</groupId>    
    <artifactId>camel-mustache</artifactId>
    <version>x.x.x</version> <!-- use the same version as your Camel core version -->
</dependency>

Please refer to How to build integration flow packages containing additional Camel components

2. Create your Mustache template. Save the file as MUSTACHE in your Integration Flow directory. In this example:

3. Refer to MUSTACHE file in the integrationFlow.xml

        <route id="main">
            <from id="direct-start" uri="direct:start"/>
            <setBody>
                <simple>${body.replaceAll("\(|\)", "")}</simple>
            </setBody>
            <convertBodyTo id="convert-body-to-string" type="java.lang.String" charset="UTF-8"/>
            <unmarshal><custom ref="json-jackson"/></unmarshal>
            <to uri = "mustache://MUSTACHE"/>
        </route>

Transformed exchange will be available as Out-Body
