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
