+The client's organization ID is extracted from the DSN or can be set with the `org_id` option.
+If the organization IDs do not match, the SDK will start a new trace instead of continuing the incoming one.

+An optional organization ID for your Sentry project.

+The SDK will try to extract the organization ID from the DSN. If it cannot be found, or if you need to override it (if you use Relay or self-hosted),
+you can provide the ID with this option.
+
+The organization ID is used for features like <PlatformLink to="/configuration/options#strict_trace_continuation">strict trace continuation</PlatformLink>.

 An optional list of functions that should be set up for tracing. For each function in the list, a span will be created when the function is executed.
