REST API not updating mandatory fields on incident formIssue We are currently using an API to create incidents. When we use the REST API Explorer all the fields display all values as applied. Although when we use an external API with the same values, 3 fields (category, subcategory, cmdb_ci) display with null value. We have followed Docs (https://developer.servicenow.com/app.do#!/rest_api_doc?v=madrid&id=r_TableAPI-POST) and using user "muleIntegrationUser" although it is producing errors. Payload below is from REST API Explorer Steps to Reproduce :curl "https://<instance_url>/api/now/table/incident" \--request POST \--header "Accept:application/json" \--header "Content-Type:application/json" \--data "{\"category\":\"Enterprise Shared Platforms\",\"subcategory\":\"Outbound Comms Management\",\"cmdb_ci\":\"c937df924fcf2200081cfe501310c774\",\"assignment_group\":\"05f614684fc36200081cfe501310c7f4\",\"caller_id\":\"72d392914fba1fc0081cfe501310c7e2\",\"opened_by\":\"72d392914fba1fc0081cfe501310c7e2\",\"short_description\":\"Test Incident\",\"state\":\"2\",\"comments\":\"more comment\"}" \--user '<user_name>':'<password>'ReleaseLondon P10CauseACL issue, User has to be granted ITIL role to access the REST API further.
