From the MSDOS command window, type in the following curl commands:
--------------

1) To authenticate with API user: qcapi with password: OKCStest1

curl -X POST  https://xyz-23a-ka-irs.custhelp.com/km/api/latest/auth/integration/authorize -H "Accept: application/json" -H "Content-Type: application/json" -H "kmauthtoken: {\"siteName\":\"xyz_23a_ka\"}" -d "{\"login\": \"qcapi\", \"password\": \"OKCStest1\", \"siteName\": \"xyz_23a_ka\"}"
==>
{"authenticationToken":"bGl2ZXRlc3RfMjNhX2thOmZkVXI0WVptUXd0S2VZOUg0cGFKL1QwSU9sQ2F3ZTgyNnBRamZNYTNvZkJ0aHFBUkxVdFRUMXlqOXBaQUV5YkQ4QmhBMExVRDZ1UTJWMTNMQTJVd1NQeGovYytzZ05UNFd6NlFEWWtFbFNZYzY4OEorU0tuSWNCY1ZUUExlcVdyU1V6YjZOQjNQOEwyWDl3NzhJOU4wclcvbUZ0Nk8xNm45Vk02WjhRbzl3ND0="}

2) To authorize(impersonate) with Console (or Contact) user for the subsequent KA REST API calls.  For this case, I choose to authorize with Console user: dev_Rnt with password: 5HuZv5HS

curl -X POST  https://xyz-23a-ka-irs.custhelp.com/km/api/latest/auth/authorize -H "Accept: application/json" -H "kmauthtoken: {\"siteName\":\"xyz_23a_ka\",\"integrationUserToken\":\"bGl2ZXRlc3RfMjNhX2thOmZkVXI0WVptUXd0S2VZOUg0cGFKL1QwSU9sQ2F3ZTgyNnBRamZNYTNvZkJ0aHFBUkxVdFRUMXlqOXBaQUV5YkQ4QmhBMExVRDZ1UTJWMTNMQTJVd1NQeGovYytzZ05UNFd6NlFEWWtFbFNZYzY4OEorU0tuSWNCY1ZUUExlcVdyU1V6YjZOQjNQOEwyWDl3NzhJOU4wclcvbUZ0Nk8xNm45Vk02WjhRbzl3ND0=\"}" -d "userName=dev_Rnt&password=5HuZv5HS&siteName=xyz_23a_ka&userExternalType=ACCOUNT"
==>
{"authenticationToken":"{\"localeId\":\"en_US\",\"knowledgeInteractionId\":null,\"interactionIdGenerated\":null,\"appId\":null,\"siteName\":\"xyz_23a_ka\",\"interfaceId\":null,\"requiresBillable\":null,\"captureAnalytics\":null,\"integrationUserToken\":null,\"userToken\":\"r9JYhJJfQR7wa9IH+LDMFrdk6Tk41ttXJ6KG9HOWoz9nqJ/hg5OWoAS4ODoT4SS2h/rNs+nK8hI5zR2DDeldp7a3szyurESZDnvwP4tN/TAvaOYMhR6CWqeHVYvbxzxLpZsMFBhECArTlLlQqP0ipQ==\",\"referrer\":null,\"querySource\":null,\"clientIP\":null,\"localeOverride\":null}","user":{"recordId":"4B474D0DF88648E9A42A04F76E384814","name":"Rnt_dev Rnt_dev","email":"invalid.email@rnt.invalid","externalId":30,"externalType":"ACCOUNT","isActive":true,"isLocked":false,"adminUser":true,"banUser":false,"dateAdded":"2023-04-25T19:30:24-0400","dateModified":"2023-04-25T19:38:12-0400","firstName":"Rnt_dev","isDefaultAdministrator":false,"lastName":"Rnt_dev","login":"dev_Rnt","canReceiveEmailNotificationsForAssignedTasks":true,"canReceiveEmailNotificationsForTasksICanPerform":true,"reputationPoints":10,"showEmail":false,"showName":false,"subscribeOnTopicCreation":false,"subscribeOnTopicReply":false,"subscriptionSchedule":1,"defaultLocale":{"recordId":"en_US"}}}

3) Now we are invoking the subsequent KA REST API calls (as Console user: dev_Rnt with whatever its security roles/permissions).  For this case, I simply get/retrieve the published KB12 answer

curl -X GET https://xyz-23a-ka-irs.custhelp.com/km/api/latest/content/docId/KB12? -H "Content-Type: application/json" -H "kmauthtoken: {\"siteName\":\"xyz_23a_ka\", \"interfaceId\":1, \"integrationUserToken\":\"bGl2ZXRlc3RfMjNhX2thOmZkVXI0WVptUXd0S2VZOUg0cGFKL1QwSU9sQ2F3ZTgyNnBRamZNYTNvZkJ0aHFBUkxVdFRUMXlqOXBaQUV5YkQ4QmhBMExVRDZ1UTJWMTNMQTJVd1NQeGovYytzZ05UNFd6NlFEWWtFbFNZYzY4OEorU0tuSWNCY1ZUUExlcVdyU1V6YjZOQjNQOEwyWDl3NzhJOU4wclcvbUZ0Nk8xNm45Vk02WjhRbzl3ND0=\", \"userToken\" : \"r9JYhJJfQR7wa9IH+LDMFrdk6Tk41ttXJ6KG9HOWoz9nqJ/hg5OWoAS4ODoT4SS2h/rNs+nK8hI5zR2DDeldp7a3szyurESZDnvwP4tN/TAvaOYMhR6CWqeHVYvbxzxLpZsMFBhECArTlLlQqP0ipQ==\"}"
