might want to checkout Estuary Flow, realtime connectors for stripe directly, or the HTTP inject webhook, and then data can be exposed as a kafka-compatible endpoint using the destination option dekaf. good solution for realtime.
for non-realtime / batch, 1 option is Airbyte, which has a strip connector, but i'm not sure best way to get the data into starrocks, since they don't have a starrocks destination. it's possible to write data to iceberg tables, and then query thru starrocks.
both these tools are open source, although estuary flow will be harder to setup locally, whereas airbyte is easy.
