B1if: How to call PUT Http in json format

Hi,

I would like to perform an http call in json format to call an API that is exposed.

here is my http call method with PUT and i have an error message

com.sap.b1i.xcellerator.XcelleratorException: XCE212 Error performing the HTTP-call, HTTP-status is 404, Not Found

I use a httpCall atom :

<call xmlns="">

  <!--identifier-->

  <destHost>urlmysebservice/</destHost>

  <destPort>80</destPort>

  <destPath>stocks/</destPath>

  <query>1004</query>

  <!--<proxyHost></proxyHost>

  <proxyPort></proxyPort>-->

  <method>PUT</method>

  <authentification>basic</authentification>

  <user>userws</user>

  <password>pwd</password>

<!-- <user2query> </user2query>

  <password2query> </password2query>

  <trustStoreURI>urlmysebservice</trustStoreURI>

  <keyStoreURI></keyStoreURI>-->

</connect>

<!--optional - document type definition-->
