Streamline Connected App Integrations with OAuth 2.0 Endpoints (Generally Available)
Where: This change applies to Lightning Experience and Salesforce Classic in Enterprise, Performance, Unlimited, and Developer editions.
How: This solution follows the OAuth 2.0 Dynamic Client Registration Protocol and the OAuth 2.0 Token Introspection specification. Configure connected app integrations with OAuth 2.0 endpoints with these steps.
After creating a connected app, generate an initial access token and configure your new endpoints. And be sure to register your initial access token and integrate your OAuth 2.0 endpoints with your OAuth 2.0 client, such as MuleSoft.
