BigCommerce will be deprecating the use of Transport Layer Security (TLS) 1.1 on October 31, 2020 and customers will be required to utilize TLS versions 1.2 or greater. Any access to services that currently rely on TLS 1.1 or older will no longer be supported on this date. BigCommerce recommends customers discontinue the use of older web browsers or older customized integrations and upgrade to newer web browser versions that support TLS 1.2 in addition to updating integrations to support TLS 1.2.
All modern web browsers support TLS 1.2, so there is no expected disruption of service for the storefront.
However, if you are a user of BigCommerce’s public APIs or Webhooks, please make sure your API requests are being sent using TLS 1.2+, and that your webhook recipient environment supports TLS 1.2+ connections.
BigCommerce is actively monitoring customer usage of our API and will notify those that are using TLS 1.1. Please update any integrations or services using our API to utilize TLS 1.2 or higher.
