Frequent errors:

  • The date has not been submitted in the YYYYMMDDHHMMSS format (year, month, day, hour, minute, second).
  • The date is not based on the UTC time zone (Coordinated Universal Time).
    Make sure you use date functions in your programming language that will generate a UTC hour (e.g.: gmdate in PHP).
  • The time must be calculated using the 24h format, not 12h.
  • The buyer has waited for too long before clicking on Pay.
  • The buyer was using browser history.
