Connect ServiceNow to GitHub account

• I created a developer app connection configuration in GitHub

  • https://github.com/settings/apps/servicenow-dev
  • Saved private key to personal computer (Dell 14)

• ServiceNow OAuth setup

  • I’m working through these steps: https://docs.servicenow.com/bundle/paris-devops/page/product/enterprise-dev-ops/concept/dev-ops-github-apps-oauth-auth.html

    • In the ‘Register GitHub as an OAuth Provider (Authorization Code)’ section, there is a reference to ‘OAuthDevOpsGitHubHandler’, which doesn’t exist in my SN developer instance. I’m kind of stuck at that point. I don’t know if I can use an existing script include (System UI → Script Includes - search for *Oath) or what I would include in a new script include. I tried selecting another oath script include but authentication to my GitHub app fails.

      • At 21:40, they cover the equivalent script include.

var OAuthGitHubHandler = Class.create();

    interceptRequestParameters: function(requestParamMap) { 
        // Add/Modify request parameters if needed 
        this.preprocessAccessToken(requestParamMap);
    },
    parseTokenResponse: function(accessTokenResponse) { 
        this.postprocessAccessToken(accessTokenResponse); 
    },
