Hello everyone,

I am pretty new in both automation tests and postman and would appreciate your advice.

I have such request in Pre-req scripts

pm.sendRequest({

  url:  "https://uuidentity.plus4u.net/uu-oidc-maing02/bb977a99f4cc4c37a2afce3fd599d0a7/oidc/grantToken", 

  method: 'POST',

  header: {

    'Accept': 'application/json',

    'Content-Type': 'application/x-www-form-urlencoded'

  },

  body: {

      mode: 'urlencoded',

      urlencoded: [

        {key: "accessCode1", value: "XXX", disabled: false},

        {key: "accessCode2", value: "XXX", disabled: false},

        {key: "grant_type", value: "password", disabled: false},

        {key: "scope", value: "openid https", disabled: false},

    ]

  }

}, function (err, res) {

    pm.environment.set("TOKEN",res.json().id_token);

});

And my question is how to use (get) variables stored at the environmental level and use them to “value” to be this script correctly sent. I do not want to use visible passwords in these values.

        {key: "accessCode1", **value: "XXX"**, disabled: false},

        {key: "accessCode2", **value: "XXX"**, disabled: false},

Many thanks for your help
