To check if an API is up or down in Pega 8.5.6 in Pega Cloud, you can use any REST client tool like Postman or cURL to send a GET request to the API endpoint URL.
For example, to check the status of the API endpoint URL "https://hostname/prweb/api/ApplicationAPI/Work/CreateNewFlow", you can send a GET request to that URL using a REST client tool. If the API is up and running, you should receive a response with an HTTP status code 200 OK. If the API is down, you may receive an HTTP status code 404 Not Found or 500 Internal Server Error, depending on the reason for the failure.
Additionally, you can also monitor the logs in Pega to check for any error messages related to the API. If there are any issues with the API, the logs may provide more details about the cause of the issue. You can access the logs in the Pega Cloud management console or through Pega's DevOps pipeline.
Finally, you can also set up monitoring and alerting for the API using tools like Pega Predictive Diagnostic Cloud (PDC) or other third-party monitoring tools. These tools can help you proactively monitor the health of your API and alert you in case of any issues.
