The GPC-Trace-ID header is a unique identifier associated with each request sent to our APIs. This trace ID is automatically generated by our system to assist with request tracking, debugging, and support.

You do not need to include this header when sending requests.

When contacting GPC Support about a specific API call, please include the GPC-Trace-ID found in the response headers. This will significantly improve our ability to investigate and respond to your inquiry.

We recommend logging or storing the GPC-Trace-ID from responses as part of your internal monitoring and troubleshooting processes.
