# Try the Software Management Services API You will need tokens from two different accounts to use the Software Management Services API Console, a ThingSpace API Token and a Session Token: - The ThingSpace API Token is available after you sign in to your ThingSpace Develop account. Go to [Key Management](https://thingspace.verizon.com/account/keymanagement/) in your Account Settings. Refresh the Token and then copy it to the clipboard. Return to the API Console page and paste it into the _Authorization: Bearer_ field below. - Obtain a Session Token by signing in to your UWS account using the `POST /api/m2m/v1/session/login` request of the Connectivity Management API. Use the session token that is returned in the response as the `VZ-M2M-Token` parameter value in the requests on this page. NOTE: ThingSpace API Tokens are valid for one hour. Session tokens stay valid as long as they are being used, but expire after 20 minutes of inactivity. ## Where to start After you have your tokens, here is a suggested sequence of API requests to get you started: 1. Use the `GET /subscriptions` request to see the status of your account's Software Management Service subscription. 2. Use the `GET /firmware` request to retrieve the list of available firmware upgrades. 3. If your account has an MRC subscription, use the `POST /licenses` request to assign licenses to devices that you want to upgrade. 4. Use the `POST /upgrades` request to schedule a firmware upgrade for devices. Note that the firmware must match the device (make, model, current firmware version) or you will get an error back. 5. Use the returned upgradeId in a `GET /upgrades` request to view the upgrade information. 6. If you aren't ready for devices to be upgraded yet, use the `DELETE /upgrade` request to cancel the upgrade.
