Welcome to Algorand!
You can emit logs on Algorand and can pull all the logs of an application regularly using the indexer. However, to my knowledge, there is no ready-to-use push service that would allow you to listen. You will need to pull manually.
Logs are described there: Discover AVM 1.0 | Algorand Developer Portal (additional opcodes) Access to logs via indexer: indexer - Algorand Developer Portal (each SDK has a related function)
