Hi,
If I want to consume a REST web service with HTTP data route, I would do the following steps:
* Create a **[XML](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/creating_data_sources_and_base_views/xml_sources/xml_sources)** / **[JSON](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/creating_data_sources_and_base_views/json_sources/json_sources)** data source based on content type.
* Choose the appropriate GET/PUT/POST HTTP methods.
* Add necessary HTTP headers.
* Specify POST body for POST/PUT methods. While doing so,
I would make sure to understand all the possible values the service would expect as non-null and what values might be constrained by the primary key.
In case you want to obtain the values dynamically, you could use **[Interpolation Variables](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/creating_data_sources_and_base_views/path_types_in_virtual_dataport/path_types_in_virtual_dataport#paths-and-other-values-with-interpolation-variables)** in the URL or in the POST body section like:
> “<web_service_url>?<field_name>=@<interpolation_variable_name>”
You can take a look at the **[IDU Requests](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/restful_architecture/restful_web_service/idu_requests)** section of Virtual DataPort Administration Guide for more information.
You can also refer to similar community Q&A for more details:

Hope this helps!
