Sends application trace data to Cloud Trace for viewing. Trace data is collected for all App Engine applications by default. Trace data from other applications can be provided using this API. This library is used to interact with the Cloud Trace API directly. If you are looking to instrument your application for Cloud Trace, we recommend using OpenTelemetry.
To call this service, we recommend that you use the Google-provided client libraries. If your application needs to use your own libraries to call this service, use the following information when you make the API requests.
Discovery document
A Discovery Document is a machine-readable specification for describing and consuming REST APIs. It is used to build client libraries, IDE plugins, and other tools that interact with Google APIs. One service may provide multiple discovery documents. This service provides the following discovery document:
A service endpoint is a base URL that specifies the network address of an API service. One service might have multiple service endpoints. This service has the following service endpoint and all URIs below are relative to this service endpoint:
