How to use the Web API tile with ServiceNow

This article covers how to use the Web API tile to query data from ServiceNow and display this data in SquaredUp.

We recommend you use the ServiceNow tile which offers easier configuration and the ability to use the donut visualisation. However, for more flexibility and advanced configurations you may prefer to use the Web API tile with ServiceNow as described in this article.

This article covers these areas:

  1. Configuration in ServiceNow
  2. Adding a ServiceNow provider in SquaredUp.
  3. Configuring the Web API tile for ServiceNow


  • The SquaredUp server must have access to your ServiceNow instance on port 443 (HTTPS), since it is the server that connects to ServiceNow, and not your users' browser.
  • A ServiceNow instance.
  • The username and password of the account to use for requests (we recommend a service account). This ServiceNow user must have the 'web_service_admin' role and check 'Allow access to this table via web services'. You may need some help from a ServiceNow admin to get an account with the correct privileges.
  • If you use a proxy server you may need to configure the proxy to allow the Web API tile to communicate with ServiceNow.

Configuration in ServiceNow

  1. In the Application Navigator (left-hand menu) go to System OAuth and click Application Registry.
  2. Click Create an OAuth API endpoint for external clients.
  3. Call it something like SquaredUp to make it easier to remember, all the other defaults should be fine.
  4. Once you've created the endpoint, open the entry to view the client ID and secret (click the padlock next to the client secret to see it!) and copy these into a notepad for use later.

Adding a ServiceNow provider in SquaredUp

  1. Log on to SquaredUp and navigate to the right-hand menu ☰ then system and then click on the web api perspective.
  2. Click Add new provider.
  3. Change the provider type to OAuth and type in a suitable name, e.g. ServiceNow.
  4. Change the grant type to password.
  5. The base URL should look something like https://instancename.service-now.com/api/now/ where instancename is your instance. If ServiceNow is installed on-premises, this may be something different. This URL is prepended to every request URL.
  6. The token URL will be something like https://instancename.service-now.com/oauth_token.do where instancename is your instance.
  7. username and password are exactly those used to sign into the account which was setup with the permissions mentioned in the prerequisites.
  8. client id and secret are taken from the notes you made earlier.
  9. Leave the authorisation scope empty
  10. Click add provider.

If the configuration is correct you will see a green tick.

If the provider is not authorized it could be that some of the provider configuration is incorrect (for example the username, password, secret etc), or if you use a proxy it could be that the proxy is not configured. See How to configure SquaredUp to use a proxy.

Walkthrough: Configuring the Web API tile for ServiceNow

This walkthrough takes you through configuring a simple tile to show a list of the open incidents.

You'll find the ServiceNow document with the relevant information here: ServiceNow Aggregate API

  1. Create a new dashboard and click on the Web API tile.

  2. Select Web API (Grid).

  3. The scope section allows you to specify resources, which can be used later in the tile configuration to insert resource properties into the query. For this walkthrough you can leave the scope empty.
  4. In the provider section select the ServiceNow provider that you created.
  5. In the http mode section paste table/incident into the URL box to make this a GET request to table/incident. This base URL is prepended to the URL.
  6. In the headers & data section click add under data to add the following parameters to the request to select the correct data and format for the grid:

    • name: sysparm_display_value value: true. This will show the display value of any columns which are IDs by default.
    • name: sysparm_fields value: sys_id,urgency,short_description,severity,state,assigned_to. This will only select the fields we are interested in. You can compile a list of fields using the REST API Explorer on your own ServiceNow instance.
    • name: sysparm_limit value: 20. This will limit the amount of results to the first twenty.
    • name: sysparm_query value: active=true. This will show open tickets only.
  7. In the response data section, paste result into the box.

    Rows of data should now be shown.

    The grid columns and grid options sections allow you to configure the columns and column names.

  8. In the grid columns section, hide the sys_id column, rename and reorder other columns as you like. Some columns, like assigned_to will be returned as [object Object]. Click edit next to these columns, and then click the {} icon, then select the display value to have these display correctly.
  9. In the grid options section, we can set the row link to make each row hyperlink to that ServiceNow incident. To make each row replace the sys_id with the one from that resource the URL should be https://<your-instance>.service-now.com/nav_to.do?uri=%2Fincident.do%3Fsys_id%3D{{sys_id}}
