Map html to REST including tags

Summary

When trying to map attributes containing html formating the tags are just removed by OIC.

Content

We are trying to implement an integration between DB-AQ and a Oracle Service Cloud (REST). 

The incoming payload that has html tags for Service Cloud formatting (e.g. <p>Dear Customer</p> <p>this is a welcome e-mail</p>) but when mapping this attribute to the REST-Endpoint OIC just removes all tags and passes only the text to the endpoint. 

What are we doing wrong here? Is there a way to map the whole content without losing the html tags? 

Thanks in advance, dear forum
