Hi Brendan,
Great work! You might be interested in our new API design guidelines for SDKs, here: Unified SDK API
With two “reference implementations” being Python and .NET.
We were planning to officially announce both the new SDKs and the guidelines soon ™ (with more context about why we’re doing this), but given that you’re working on your own SDK it seems appropriate for you to know sooner. Feel free to post questions about the new API in https://forum.sentry.io/c/sdks/sdks-unified or ask on the issue trackers of the respective implementations.
