Send HTML message with links using Mailgun

I am trying to send and HTML based message which includes a link using mailgun in Java. The issue is that the HTML code is displayed as is in the email client and it does not render it as HTML formatted content.

I am refering to the example given in this URL -

https://documentation.mailgun.com/user_manual.html#sending-via-api

Client client = Client.create();
       client.addFilter(new HTTPBasicAuthFilter("api",
                       "key-***"));
       WebResource webResource =
               client.resource("https://api.mailgun.net/v3/sandbox***.mailgun.org/" +                            "messages");
       FormDataMultiPart form = new FormDataMultiPart();
       form.field("from", "Admin <[email protected]>");
       form.field("to", "User <[email protected]>");
       form.field("subject", "Hello User");
       form.field("text", "Testing some Mailgun awesomness! <BR> this should be in new line &lt;BR&gt;this shoud aso be be new line");
       return webResource.type(MediaType.MULTIPART_FORM_DATA).post(ClientResponse.class, form);

Can anybody having experience with mailgun help me. I need to send email with clickable links in it (anchor tags).

Solution

From the api documentation try the following:

 form.field('html','<html><a href="http://stackoverflow.com">HTML version of the body</a></html>');
