Create a credentials variable for Dynamic Analysis login scripts with the REST API

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.

See the example Selenium scripts.

Example Python code for using the scan engine variables API feature is available from https://github.com/anon-veracoder/veracode-dynamic-analysis-api-examples.

To complete this task:

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. Send the following request:

   http --auth-type=veracode_hmac POST "https://api.veracode.com/was/configservice/v1/scanner_variables" < 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": "Passw0rd123"
   }

   This example adds the totp property set to true to add Time-based One-Time Passwords (TOTP) support. You use TOTP for URLs that require multi-factor authentication (MFA). See the example Selenium scripts.

   {
      "description": "Password key for my application",
      "reference_key": "MY_PASSWORD_KEY",
      "value": "Passw0rd123"
      "totp": true
   }

   This is an excerpt of a Selenium login script that references the key MY_PASSWORD_KEY. When the dynamic scan engine executes the login script, the value Passw0rd123 replaces the key ${MY_PASSWORD_KEY} at runtime. The login script does not return the key value, which remains hidden from users.

   }
