  title: Bugsnag Build Builds Traces API
  description: The Bugsnag Build API allows you to provide information about your application builds, releases, and deployments. By notifying Bugsnag when you deploy, you can track which releases introduced new errors, view error trends across releases, and identify regressions. The API accepts build metadata including version numbers, source control information, and release stages. It integrates with CI/CD pipelines to automate release tracking.

      summary: Send trace data
      description: Sends OpenTelemetry span data to Bugsnag using the OTLP HTTP protocol. Accepts payloads in JSON format (application/json) or protobuf format (application/x-protobuf). Spans represent individual operations such as HTTP requests, database queries, or function calls. Bugsnag assembles spans into traces to visualize request flow and identify performance bottlenecks. The maximum payload size is 1MB, and a batch size of approximately 200 spans is recommended.
