On February 13, 2020 all API requests to POS Portal API Web services began receiving error response message "The provided Timestamp header is outside of the acceptable bounds. Please retry using the current time.”. This impacted API requests from Portal Cloud, Portal Access, Direct Merchant eCommerce, and Re-seller eCommerce.
Timeline (all times Pacific Standard Time)
The issue was identified that one of the API back-end system clock was out of synchronization with official time sources and caused a time drift 182 seconds. This difference in time between client and server caused API authentication errors and rejected all API requests.
Resolution and recovery
System clocks were manually synchronized with official time sources.
