# Aggregation service This directory contains the implementation of the client-side logic for the [Aggregation service](https://github.com/WICG/attribution-reporting-api/blob/main/AGGREGATE.md#data-processing-through-a-secure-aggregation-service) proposed for the [Attribution Reporting API](https://github.com/WICG/attribution-reporting-api). ## Command-line tool A command-line tool that generates aggregatable reports for testing is available. Please see //tools/aggregation_service's [README](../../../tools/aggregation_service/README.md) for more detail ## Payload encryption The details of how aggregatable report payloads are encrypted are provided in a separate [README](./payload_encryption.md). **TODO**: Expand this README.
