Yes , there are two threads in this.. Actually initially I have asked that question and then I had the other question which is second thread ..
As per your answer to 2nd question..
?token=00000043547 is parsed OOTB into the Arg List with a key of "token" and a value of "00000043547".
--> Yes, this is correct automatically when I create VS, LISA identifies this and covert token as key in VSI.
In this scenario, the REST DPH does not need to parameterize that value using the URLPARAM construct. The base path that is generated in this scenario should not contain a reference to the query string.
-- > What I assume as per your comment is base path without query string ..
that will be look like /web/CreditLimit
but client is invoking with URI like /web/CreditLimit?token=00000043547
so how do my client will establish connection with LISA base path, if the base path does not contain token as per your above comment ?
it will be like 404 not found error ..
