integration between bmc remedy and serviceNow using wso2 - wso2-api-manager

Question

we would like to integrate incident module between BMC Remedy and ServiceNow ITSM applications using ESB-WSO2, need assistance on this to achieve this integration.
Use case: Service now has to create incident then WSO2 will consume the request and process then processed request will be send to Remedy. This is nothing but a e-bonding or you can call it as ticket replication.
Any help would be much appreciated

Here is a sample API for you. Supposing that you have already installed ServiceNow connector.
You can call it from Postman using GET or browser, http://{yourWso2EiServer}:8280/serviceNow/test
After testing you can change method to POST and try to send different messages using POSTMAN. Then you will have to evaluate properties from a message, using like"expression"="json-eval($.tablename)" instead of "value"= in you Property mediators and your message must be an application/json and contain this field, like
{"tablename":"incident"....
