HTTP Get/post Request with SAML2.0 Assertion to NWGW

Hi,

We need help with SAML2.0 on NWGW. We have configured SAML2.0 on NWGW 731 with IDP as external provider.

We are testing the NWGW Service with HTTP get from NWGW client.

In the HTTP Request how should the SAML2.0 XML should look like ?

Should we use Bearer / Holder of Key / Sender Assertion ?

Note We are not using OAuth currently, we are looking to use SAML 2.0 only and need a sample XML that can used to send HTTP Get request from NWGW client to NWGW.

Thanks

Kumar
