You can override the default content header in `Header/Value` field, if you want (bear in mind that Pipefy do not provide any validation here, please):
{“content-type”: “text/xml”}
and add a xml text as body:
<?xml version="1.0" encoding="UTF-8"?> <note> <to>Tove</to> <from>Jani</from> <heading>Reminder</heading> <body>Don't forget me this weekend!</body> </note>
