Hi, Is it somehow possible to set in a pre-request script the current value of a global/environment variable instead of the initial value? My script: ```auto const refreshRequest = { url: 'https://securetoken.googleapis.com/v1/token?key=' + pm.globals.get("webApiKey"), method: 'POST', header: 'Content-Type:application/json', body: { mode: 'application/json', raw: JSON.stringify( { grant_type: 'refresh_token', refresh_token: pm.globals.get("refreshToken") }) } }; var getToken = true; if (!pm.globals.get('expirationTime') || !pm.globals.get('idToken')) { console.log('Token or expiry date are missing') } else if (pm.globals.get('expirationTime') <= (new Date()).getTime()) { console.log('Token is expired') } else { getToken = false; console.log('Token and expiry date are all good'); } if (getToken) { pm.sendRequest(refreshRequest, (err, res) => { console.log(err ? err : res.json()); if (!err) { console.log('Saving the tokens and expiry date') var responseJson = res.json(); pm.globals.set('idToken', responseJson.id_token) pm.globals.set('refreshToken', responseJson.refresh_token) var expiryDate = new Date(); expiryDate.setSeconds(expiryDate.getSeconds() + responseJson.expires_in); pm.globals.set('expirationTime', expiryDate.getTime()); } }) } ``` As you can see I have several `pm.globals.set` calls in the script, which set rather security relevant variables, like id and refresh tokens. I don’t want these variables to be synced to all colleagues. When I run `pm.globals.set('refreshToken', responseJson.refresh_token)` this does not only set the current value, it set’s the initial value as well, what I try to prevent. How can I achieve this? I hope for some good tips, Dennis ---

Hi Dennis, From any script (collection/request pre-request/test), it is only possible to set the current value. Depending on your setting `auto persist variables values` the modified current value will be copied to the initial value. If that is something you don’t want, you can turn it off. Here’s a simple flowchart from [our docs](https://www.getpostman.com/docs/v6/postman/collection_runs/using_environments_in_collection_runs) explaining it visually ![Using_environments_in_collection_runs](https://us1.discourse-cdn.com/getpostman/original/3X/d/c/dc60bfbb2970167681bac9311f3baf30bb188dcc.jpeg) Here’s where you can find this setting ![Postman](https://us1.discourse-cdn.com/getpostman/original/3X/3/5/3566f42752c1e920096b0fc4843b4443a018ff7d.png) ---

Oh, thanks, this is exactly what I was looking for 🙂 I looked in the documentation for something like this. Unfortunately, the documentation is even if it’s easily understandable, sometimes a bit unintuitively organized. I often had to look through a lot of pages to find the relevant info. I hope that Postman gets it’s already good documentation as good as the awesome Postman product! 😃 ---

Thanks, Dennis Sure, I will let our team know about this. We are currently working on improving our docs. ---

Is there a way to enforce this setting for a shared workspace? Otherwise if anyone in the team forgets this setting, tokens might be uploaded right (if you have a test, which uses setEnvironmentVariable)? ---

@clemens.peters currently there’s no way to enforce this for a shared workspace. There’s already a [feature request](https://github.com/postmanlabs/postman-app-support/issues/5146) which has been filed for this. You can subscribe to the thread for any future updates around that. ---

Hi, I’m using Postman v9.0.5, but in Settings menu under General tab, there isn’t ‘Automatically persist variable values’ option. How can I automatically update environment variable’s initial value with current value? Thanks in advance, Andrea ---

No ‘Automatically persist variable values’ option exists in Postman. I don’t know how to automatically update environment variable’s initial value with current value. Anyone can help in postman support?
