You can use the Dynamic Analysis API to update credentials fields in login scripts by creating a scan engine variable that the API uses at runtime.


With a variable login script you do not need to know the credentials for the application to which Dynamic Analysis is logging in, nor do you need to create a new login script every time the credentials values change.

Example Python code for using the scan engine variables API feature is available from


  1. Add the values for the description, value, and, optional, reference_key properties in the JSON file. The reference key is the value you use in your login script. Alternatively, you can use the scanner_variable_id that the API returns in response to a POST in your login scripts.

  2. Run this command:

    http --auth-type=veracode_hmac POST "" < input.json

This is an example of how to create a new scan engine variable key-value pair:

   "description": "Password key for my application",
   "reference_key": "MY_PASSWORD_KEY",
   "value": "hunter2"

This is an excerpt of a Selenium command in a login script that references the key MY_PASSWORD_KEY. When the dynamic scan engine executes the login script, the value hunter2 replaces the key ${MY_PASSWORD_KEY} at runtime.
