Karate Test Framework -Storing credentials outside of github - karate

Question

I have Karate Tests for the APIs which are on Amazon API Gateway. As such, in my Karate Tests I have to provide client_id and client_secret for authentication. I was wondering if there is a way I could store the credentials outside my github repository and use it at run time. Is it possible to do that in Karate ?
Here is how my tests look like:
Feature: API Test all endpoints using Karate
Background:
* configure ssl = true
* url baseUrl
* def res = (env == 'qa'? 'classpath:endpoints/user-login.feature' : 'classpath:endpoints/user-login-dev.feature')
* def token = call read(res)
* def headerData = {Authorization: #(token.nextGen),Accept: 'application/json;v=1'}
* headers headerData
Here is the user-login.feature file
Feature: API Test using Karate
Background:
* configure ssl = true
Scenario: Get authorization header
Given url 'https://api.cloud.xyz.com/oauth2/token?client_id=****&client_secret=****&grant_type=client_credentials'
When method get
Then status 200
And def tokenType = response.token_type
And def accessToken = response.access_token
* def nextGen = tokenType + ' '+ accessToken
* def headerData = {Authorization: nextGen,Accept: 'application/json;v=1'}
Any pointers on how I can have the client_id and client_secret passed to the tests at run time and not stored in github.
Thanks in advance!

The easiest way would be to pass them as Java system properties via the command-line, which you can very easily do from a test or from a CI triggered run.
Refer to the documentation here: https://github.com/intuit/karate#dynamic-port-numbers
An example of how it could look like in your case:
Given url 'https://api.cloud.xyz.com/oauth2/token'
And param client_id = karate.properties['client.id']
And param client_secret = karate.properties['client.secret']
And param grant_type = 'client_credentials'
And on the command-line:
mvn test -DargLine="-Dclient.id=**** -Dclient.secret=**** -Dkarate.env=qa"
