How can I get free or trial ExactTarget instance. I need to do ExactTarget SAML2.0 Single Sign-On connector development, integration and testing. Is there any step by step documentation available so that I can work on ExactTarget SAML2.0 Single Sign-On ?
Developer Editions of Marketing Cloud are no longer available. However, I was told by the team that provided the Developer Edition program that developer account are still available by request. You should be able to contact your Account Representative to request one. If you still have issues, connect with me on LinkedIn and I can setup an introduction with the right person to get you one.
Details on implementing SAML SSO in Marketing Cloud are documented here.
