Get started with the Cross-Media Measurement API in just a few steps.
1
Understand the Architecture
The Cross-Media Measurement API is a resource-oriented gRPC API using Protocol Buffers. It enables privacy-preserving measurements through multi-party computation across data providers.Read the Core Concepts to understand the resource model and architecture.
2
Set Up Authentication
Authentication uses OpenID Connect and X.509 certificates for digital signatures. You’ll need to create an account and obtain credentials.
# The API uses certificate-based authentication# See the authentication guide for details
Once authenticated, you can create measurements that compute reach, frequency, or impressions across multiple data providers while preserving privacy.
message Measurement { string name = 1; string measurement_consumer_certificate = 2; MeasurementSpec measurement_spec = 3; State state = 4; Result result = 5;}
The API provides comprehensive services for measurements, event groups, requisitions, model management, and panel matching.Browse the API Reference to explore all available services and methods.
