Provide the RPC ID When Troubleshooting with Support

The response of each RPC call contains the rpc_id field, which identifies the method execution in Salesforce. Salesforce Customer Support uses the rpc_id value to aid in troubleshooting issues with an RPC call. If a call fails, the returned exception includes the rpc_id field. For more information, see Handle Errors. Even if a call is successful and returns a successful response, there can be issues, for example, slow performance in event publishing or delivery. If you determine that the issue doesn’t originate from your code and you contact Salesforce Customer Support for help, provide the rpc_id value from the response.
