Hi elastic team,
I really love the idea of synthetic monitoring and having it integrated in the uptime monitoring app. At the moment, I am working on an API as a product project and would love to use synthetic monitoring to verify that the API is working properly. I added some new journeys to the example project to test the API with some simple fetch calls. When I looked into the uptime app, I realized that there is no performance breakdown for all steps where I am not using the playwright page object. Is there a way to also gain these performance insights for API calls without using the page object from playwright?
I think it would be really cool to use synthetic monitoring for products without an UI as well.
Thanks in advance!

Hi @Moritz_Rieger, the Synthetic Agent would typically be used for real browser tests loading and interacting with websites (using a Synthetic/Playwright script). If you’re mainly after hitting API endpoints, maybe HTTP Ping monitor types in Heartbeat would be more appropriate.
There is more information on Heartbeat monitors [here](https://www.elastic.co/guide/en/beats/heartbeat/current/configuration-heartbeat-options.html), with details on the HTTP type, [here](https://www.elastic.co/guide/en/beats/heartbeat/current/monitor-http-options.html).
