Instructions to Change Worldpay URL
Action Required: Important Service Update On Tuesday, April 19, 2016, Microsoft will release an operating system security update to mitigate potential cyber-attacks on Microsoft operating systems. This update will also disable the Verisign G1 trusted root certificate on which Worldpay’s private SHA-1 certificate is based. Merchants using Windows 10 on their point of sale system (POS) will experience an interruption in processing service once the update takes place if action is not taken. Required actions for POS systems using Windows 10 To avoid service interruption your POS must be updated to Worldpay’s new URL before the April 19th deadline: https://api.lynksystems.com We strongly recommend making this change by Friday, April 15th to allow enough time to verify the update is successful. If you have questions about how to update your POS system, please contact your POS provider for support. Recommended action for POS systems using an older version of Windows We also recommend that merchants who are using older Windows operating systems update to the new URL as well, since Microsoft will eventually disable all SHA-1 connectivity by the end of 2016. We appreciate your business and we’re here to assist you in any way concerning this matter. If you have any questions, please contact your Worldpay representative.
