Error reporting HTTP API documentation

Hi All,

I’m doing a embedded linux system project with the requirement to report error live to cloud.
Sentry (python) was initially considered, but was later on considered not fit due to cpu / battery usage concerns.
Now my project requires developers to use pure http client to sent live errors.
I’m having trouble to find the doc for sentry error reporting REST API.

Can anyone link a decent doc here? Or provide some examples?

Kind Regards
