Hi Dennis,
I first configured a new environment with variables
wsse-user and the created Emarsys API User as value
wsse-secret and the corresponding password for the API User
wsse-header without an initial value
In the header for the request I added the Key "X-WSSE" with value {{wsse-header}}
Then you only need the prerequest script and add it to your request:
This is the prerequest script that I used:
/*
* This script should be used as the pre-request script for any requests made to Emarsys. In theory, it should work for any API that implements WSSE authentication as well.
* To Use:
* 1: Set an environment variable for wsse-user and wsse-secret containing your WSSE user and secret respectively
* 2: On your Headers tab, add an X-WSSE header with a value of {{wsse-header}}
*
* That's it! When you make a request, the pre-request script will generate your Nonce, Timestamp, and Digest using your secret. The 1-time-use header will be stored in the environment as wsse-header and used for your request.
