The [Historical Stats API](https://www.fastly.com/documentation/reference/api/metrics-stats/historical-stats/) and the [Real-Time Analytics API](https://www.fastly.com/documentation/reference/api/metrics-stats/realtime/) now support two new metrics for troubleshooting Private Access Token (PAT) challenges. These track the number of issued and successful PAT challenges.
