firstPartyHostsWithTracingHeaders property

A list of first party hosts and the types of tracing headers Datadog should automatically inject on resource calls. This is used in conjunction with Datadog network tracking packages like datadog_tracking_http_client

For more information about tracing headers, see TracingHeaderType.

Each request will be classified as 1st- or 3rd-party based on the host comparison, i.e.:

• if firstPartyHosts is ["example.com"]:
  • 1st-party URL examples: https://example.com/, https://api.example.com/v2/users
  • 3rd-party URL examples: https://foo.com/, https://example.net
• if firstPartyHosts is ["api.example.com"]:
  • 1st-party URL examples: https://api.example.com/, https://api.example.com/v2/users, https://beta.api.example.com/v2/users
  • 3rd-party URL examples: https://example.com/, https://foo.com/, https://api.example.net/v3/users
