A connected app integrates an application with Salesforce using APIs.
Connected apps use standard SAML and OAuth protocols to authenticate, provide Single Sign-On, and provide tokens for use with Salesforce APIs.
In addition to standard OAuth capabilities, connected apps allow administrators to set various security policies and have explicit control over who may use the corresponding applications.
For connected apps that use OAuth service providers, define the OAuth scopes and callback URL for the connected app. In return, Salesforce provides an OAuth Consumer Key and a Consumer Secret for authorizing the connected app.
For connected apps that use SAML service providers, define the Entity ID, ACS (assertion consumer service) URL, Subject Type, Name ID Format and Issuer (these should be available from the service provider) for authorizing the connected app.
