Redirect Users to Your Website After Self-Registration
Where: This change applies to Lightning Experience and Salesforce Classic in Professional, Enterprise, Performance, Unlimited, and Developer editions.
How: Salesforce web developers can add the new salesforce-self-register-starturl-enabled meta tag to your website’s Embedded Login. The meta tag auto-generates and appends the start URL to the self-registration endpoint. When a user self-registers on your website, the auto-generated start URL initiates the OAuth user-agent flow, redirecting the user back to your website.
