Salesforce is retiring the legacy Web-to-Lead and Web-to-Case Endpoints on Jan 12, 2018. Salesforce client websites using these features should be checked to ensure that the new Endpoints are installed.

As the new endpoint URL is already available, you are strongly encouraged to complete these updates as soon as possible to take advantage of the improved functionality performance.
