Hi @sarikab,

please check  below step:

• Set Up LeanIX GraphQL API:

  • Obtain LeanIX API endpoint and authentication token.
  • Familiarize with the GraphQL mutation to create a factsheet.

• Create a Script Include in ServiceNow:

var LeanIXIntegration = Class.create();
LeanIXIntegration.prototype = {
    initialize: function() {
        this.endpoint = 'YOUR_LEANIX_API_ENDPOINT';
        this.token = 'YOUR_LEANIX_API_TOKEN';
    },
    createFactSheet: function(record) {
        var payload = {
            query: `mutation {
                createFactSheet(input: {
                    type: "YOUR_FACTSHEET_TYPE",
                    name: "${record.name}",
                    description: "${record.description}"
                }) {
                    factSheet {
                        id
                        name
                    }
                }
            }`
        };
        var request = new sn_ws.RESTMessageV2();
        request.setEndpoint(this.endpoint);
        request.setHttpMethod('POST');
        request.setRequestHeader('Authorization', 'Bearer ' + this.token);
        request.setRequestHeader('Content-Type', 'application/json');
        request.setRequestBody(JSON.stringify(payload));
        request.execute();
    },
    type: 'LeanIXIntegration'
};

Create a Business Rule in ServiceNow:

• Table: Specify the table (e.g., Incident, Task).
• When: After Insert.

(function executeRule(current, previous) {
    var leanIX = new LeanIXIntegration();
    leanIX.createFactSheet(current);
})(current, previous);

Thank you, please make helpful if you accept the solution.

Hello @Yashsvi ,

Thanks for the response,

I have already tried this but i believe we have to do field mapping,setting the direction(source and target) etc.I have tried the setup in LeanIX as you mentioned and tried creating a factsheet from postman but i am getting a 405 method not found error. So i am trying to follow this document 

https://docs-eam.leanix.net/docs/setup-in-servicenow#create-an-integration-user but the thing is,according to the document we need to use a plugin for servicenow which i cant be able to do it in my personal instance.May i know if there is any alternative to plugin installation so that i can implement it in my PDI?
