How to Delete a resource in a REST Endpoint 

A resource in a REST endpoint can be deleted using 'DELETE' http method with the reource URL. This can be initiated using EVENT_BIZAPI message flow.

    PROCEDURE boston_rest_delete_rec IS
      url_params_ PLSQLAP_DOCUMENT_API.Document;

    BEGIN

      url_params_ := PLSQLAP_DOCUMENT_API.New_Document('URL_Parameters');
      PLSQLAP_DOCUMENT_API.Add_Attribute(url_params_,'p1', 'ifs/boston');
      plsql_rest_sender_API.Call_Rest_EndPoint_Empty_Body2(
      rest_service_ => 'DELETE_BOSTON_REC',
      url_params_ => url_params_,
      callback_func_ => 'P_L_S_Q_L_Rest_Test_API.REST_callback_Test',
      http_method_ => 'DELETE');

    END boston_rest_delete_rec;

Important points to consider:

• To send a DLETE request you have to call the PL/SQL method plsql_rest_sender_API.Call_Rest_EndPoint_Empty_Body(..). Note that we don't set any payload to a DELETE request.
