Explore Triggers - Auth0 Docs

Triggers are points in the Auth0 process where Actions can be added for required customization. Multiple Actions can be placed in a Trigger, executing in sequence. Excluding the Custom Token Exchange, triggers can be synchronous (blocking) or asynchronous (non-blocking). Each trigger has specific Objects and APIs. They may differ based on your connection (such as connection). To explore reference Objects and APIs for specific Actions for a trigger, select the trigger below, noting Auth0’s definition of a passwordless connection. When a user is added to a database or passwordless connection (Signup), or as part of a user’s authentication transaction (Login).
