Manual error tracking installation

Error tracking enables you to track, investigate, and resolve exceptions your customers face.

If a platform you use is not supported by error tracking, we recommend that you reach out to us or contribute to our open-source SDKs before attempting to manually send exceptions.

If you'd rather roll your own exception capturing (or if you're using a platform we don't have an SDK for), you can use the capture API or capture method to capture an $exception event with the following properties:

Property	Description
`$exception_list`	A list of exception objects with detailed information about each error. Each exception can include a `type`, `value`, `mechanism`, `module`, and a `stacktrace` with `frames` and `type`. You can find the expected schema as types for both exception and stack frames in our Rust repo
`$exception_fingerprint`	(Optional) The identifier used to group issues. If not set, a unique hash based on the exception pattern will be generated during ingestion
