HTTP Extractor in APM

Product/components used and version/fix level:

ARIS Partner Cloud

Detailed explanation of the problem:

We are currently working with HTTP Extractor to extract data through Salesforce API. Can you let us know what is the format to include multiple query string parameter in the GET operation. The Post Operation works for us with Multiple parameters but the same fails when we use GET operation.

Also we are unable to access dynamic parameter in Headers of the API during runtime. Can you help with how this can be achieved as well.

We are working on task where 4 API are to be integrated in such a way that the token retrieved from the first API will be passed to the second which will be used by that API as {access_token}.
