REST API Test: Property Transfer Problem

HI Guys,

I actually evaluating Soap NG for testing a Rest API. I am not very familar with these sort of projects (so sorry for a may be stupid question),

The API test requires a two step test. First step is generating a search key, the second step than the search with the search key.

I added the REST Endpoint and the correct ressources and filled the first Request with data from some xls files. That is working fine and the searchkey generation works.

Than i tried to safe the searchkey and the engine id with the transferproperty Option and put them into the second rest request. But this isn't working. The second correct request looks like: Get http://endpoint/resource/engineid/searchkey

But actually i found no Options to Transfer the engineid/searchkey to the Request.

Does have anybody a hint for me?

Thanks!

Regards

Timo
