We currently support writing to a webhook endpoint, PubSub/Kafka topic.
Why use Stream Transformations?
- Selective delivery: Rather than receiving bulk data, you can filter down to only the events or items you care about (e.g. specific wallets, token transfers, certain contract calls).
- Automated pipelines: Once a workflow is set up, new data flows through your filters and into your target systems (webhooks, Pub/Sub, Kafka) without manual intervention.
- Dynamic filters: You can change filtering rules (or filter data sources) on the fly, and the updates take effect immediately on running workflows. 
How Stream Transformations work?
With Allium Stream transformations, we remove the operational complexity of working with realtime streams, and you are responsible only for defining what data you care about, and where you want it sent. Check out this page for all the APIs to manage your stream transformations!
