With the variables pane, you can edit your variables and vault secrets in one location. You won't have to locate and update every variable in each [scope](/docs/use/send-requests/variables/variables/#variable-scopes) and vault secret in your [Postman Vault](/docs/use/postman-vault/postman-vault-secrets/). To access the variables pane, open a Postman element, then click Variable list icon **Variables** in the upper-right of the [workbench](/docs/getting-started/basics/navigating-postman/#environment-selector-and-variables-pane). The variables pane opens on the right where you can view the following: * **Variables in request** — View and edit your local value of variables and vault secrets referenced in a request. This also shows [variables without a scope](/docs/use/send-requests/variables/define-variables/#setting-values-for-variables-without-a-scope) that are referenced in your request. * **All variables** — View and edit your local value of variables and vault secrets that are available from your Postman elements, such as a request or collection. For example, if you have a request open, this might show variables defined in the active environment that you could choose to reference in the request. You can also hover over a reference to a variable or vault secret, then click **Variables in request** or **All variables** to open the variables pane. [Variables set as secure](/docs/use/send-requests/variables/define-variables/#secure-a-variable-value) are encrypted and masked by default. ## Variables used in a request To view variables and vault secrets used in a request, click Variable list icon **Variables** in the workbench to open the variables pane. The variables under **Variables in request** are defined at the environment, collection, or global [variable scopes](/docs/use/send-requests/variables/variables/#variable-scopes) and show your local value. This also shows vault secrets stored in your [Postman Vault](/docs/use/postman-vault/postman-vault-secrets/). You can edit your local value of a variable or vault secret that's referenced in a request. Open the variables pane, delete the existing value next to a variable or vault secret, then enter a new value. You can also hover over the reference to the variable or vault secret, delete the existing value, then enter a new value. If the request auth is set to **Inherit auth from parent**, you can view variables and vault secrets in the variables pane that are used in the **Authorization** tab of the request's parent collection or folder. Learn more about [inheriting authorization from a parent element](/docs/use/send-requests/authorization/specifying-authorization-details/#inherit-authorization). ## Access variables from an element Under **All variables** in the variables pane, you can view and update variables and vault secrets that are available from your Postman elements. For requests that reference a variable or vault secret, select **All variables** to display all variables and vault secrets a request can access. Variables and vault secrets in this section can be referenced and resolved in the element that's open. You can edit your local value of a variable or vault secret that's available from an element. Click Variable list icon **Variables** to open the variables pane, delete the existing value next to a variable or vault secret, then enter a new value. You can also take the following actions to update the variables and vault secrets from the variables pane: * If an environment isn't selected, click **Select environment** to choose an environment from the environment selector. * If there are no variables defined in the selected environment, associated collection, or globally in the workspace, click **Add** to open it in a new tab. * If there are no vault secrets defined in your Postman Vault, click **Add secrets** to open your Postman Vault in a new tab. ## Fixing empty variables An *empty variable* is a variable that's referenced in a request but doesn't have a value. For example, Postman expects to find a value for `{{cust_id}}` in the `https://postman-echo.com/get?customer_id={{cust_id}}` request. If Postman doesn't find a value for the variable, it's flagged as an empty variable and the request may fail when you send it. A variable can be empty for the following reasons: * The variable was created, but no value was added to it. * The environment that has the variable isn't active. * The variable is turned off in the respective collection, active environment, or globals. * The variable doesn't have a scope, and a value hasn't been added to it. A vault secret can also be empty if it's missing a value and is referenced in a request. Learn how to [fix empty vault secrets](/docs/use/postman-vault/troubleshoot-vault-secrets/). When you're working on an API request, Postman highlights empty variables in the **URL builder** and in the **Params**, **Authorization**, and **Headers** tabs. Postman highlights empty variable text in red. If your request has an empty variable, a red mark displays on Variable list icon **Variables** in the upper right of the workbench. To view empty variables referenced in a request, do the following: 1. Open a request with empty variables, then click Variable list icon **Variables**. 2. Under **Variables in request**, review the variables without values. To check if the variable exists and is available from the request, do the following: 1. Select the collection in the sidebar that's associated with the request, then click the **Variables** tab. You can also click **Environments** in the sidebar, then select **Globals** or one of the environments. 2. Turn on the variable, make the necessary changes to the value of the variable, or make the correct environment active. Learn more about viewing and editing variables in an element. From a request, you can [set local variables programmatically](/docs/use/send-requests/variables/define-variables/#defining-variables-in-scripts) in a pre-request script using `pm.variables.set`. When the variable is also referenced in the request, it'll display as *Resolved via script* in the variables pane. Environment, global, and collection variables set programmatically (for example, `pm.environment.set`) are saved for later use at their respective scope. If you experience issues referencing a variable set programmatically, debug your requests with the [Postman Console](/docs/use/send-requests/response-data/troubleshooting-api-requests/#debugging-in-the-console).
