How Third-Party Cookie Restrictions Impact Salesforce Canvas Apps

Fecha de publicación: Oct 1, 2024
Descripción

Prepare Salesforce Canvas apps for the new web browser restrictions on third-party cookies. Several major browsers have already disabled third-party cookies by default, including Mozilla Firefox, Apple Safari, and Brave. In January 2024, Google started a gradual rollout of its Privacy Sandbox initiative, which phased out support for third-party cookies in its Chrome browser and enforces storage partitioning in third-party contexts. However, in July 2024, Google reversed its plans to completely block third-party cookies. Instead, Chrome users can decide whether to block third-party cookies. Despite Google’s recent reversal, Salesforce moves ahead with its plans to end reliance on third-party cookies, such as moving Setup pages to the new *.salesforce-setup.com domain. Other popular browsers already block third-party cookies by default, and Salesforce expects that many users will choose to block third-party cookies due to privacy concerns.

Third-party cookies are the main mechanism that enables cross-site tracking. When Canvas apps are exposed in Salesforce via an iframe, the content may not load properly because the content is served from a different domain. To avoid problems late in development, test Canvas apps in a Salesforce container early. To design applications that don’t rely on cookies, session storage, or local storage to track users, build your Canvas apps as single-page applications (SPAs).

Solución

Salesforce Canvas doesn’t inherently require third-party cookies, so the impact of the browser restrictions is subject to your implementation of Salesforce Canvas. Canvas also doesn’t provide a solution if storage is accessed in a third-party context. We recommend that Canvas apps avoid reliance on third-party cookies and unpartitioned storage. See Alternatives to Cookies for User Tracking in Salesforce Help.

In the meantime, we recommend testing all Canvas apps to ensure that these browser restrictions don’t impact critical business workflows. If you use Google Chrome, follow Google’s testing guidance to validate key Salesforce Canvas scenarios with third-party cookies disabled. If you determine that your Canvas app is affected, consider applying the third-party cookie policies for Chrome Enterprise customers.
