Minimize distractions and reduce context switching by bridging the gap between IT service management (ITSM) and team communication. Create and manage incident reports, change requests, and service tickets, as well as manage event-driven notification subscriptions for ServiceNow record changes, in real-time, and automate routine tasks to decrease response times without leaving Mattermost.


Setup starts in ServiceNow and finishes in Mattermost.

Create an OAuth app in ServiceNow#

  1. Go to your ServiceNow instance and then to All > System OAuth > Application Registry.

  2. Select New in the top right corner, and then select Create an OAuth API endpoint for external clients.

  3. Enter the name for your app and set the redirect URL to: https://<YOUR-MATTERMOST-URL>/plugins/mattermost-plugin-servicenow/api/v1/oauth2/complete, replacing YOUR-MATTERMOST-URL with the Mattermost URL you want the ServiceNow events to post to, using lowercase characters.


A client secret is generated automatically. Copy the secret and the Client ID. You’ll need these values for the Mattermost configuration.

Upload the update set in ServiceNow#

Changing your ServiceNow instance to support subscriptions, record changes, and send change notifications to Mattermost is done by a Mattermost and ServiceNow system admin using an update set. Once created, you can download the update set from Mattermost and upload it into ServiceNow.

  1. In the Mattermost System Console, download the update set XML file.

  2. In your ServiceNow instance, go to All > System Update Sets > Retrieved Update Sets.

  3. Select the Import Update Set from XML link at the bottom of the page.

  4. Select the downloaded XML update set file and upload it. You’ll see an update set named ServiceNow for Mattermost Notifications.

  5. Select that update set, and then select Preview Update Set.

  6. Select Commit Update Set.

  7. Confirm the data loss notification, and select Proceed with Commit. Your update set is uploaded and committed to ServiceNow.

Set up user permissions in ServiceNow#

Once the update set is uploaded, it creates a new role called x_830655_mm_std.user. Users must have this role in ServiceNow to add or manage Mattermost subscriptions. You need to be a ServiceNow system admin to add the x_830655_mm_std.user role to all users who should have the ability to add or manage subscriptions through Mattermost.

  1. In your ServiceNow instance, go to All > User Administration > Users.

  2. On the Users page, open a user’s profile where you want the role added.

  3. Select the Roles tab in the table, and select Edit.

  4. Search for the x_830655_mm_std.user role, and add that role to the user’s Roles list, and select Save. That user can nowadd or manage Mattermost subscriptions.
