4b. Create a Trusted URL

In this step, you create a Trusted URL so that Salesforce's Content Security Policy (CSP) doesn't block the SlapFive embedded screens.

NOTE: This step is new due to Salesforce tightening their Content Security Policy (CSP) settings on June 16, 2025.

Go to Setup > Security > Trusted URLs and click the New Trusted URL button.

When creating the Trusted URL:

• API Name: enter SlapFive.

• URL: enter the base URL of your SlapFive instance, which is https://your_company_name.slapfive.com.

• CSP Context: Leave set to All.

• CSP Directives: Check frame-src (iframe content).

Click the Save button to create the new Trusted URL.
