 ## Allow self-service sign-up
 
 With a self-service sign-up user flow, you can create a sign-up experience for external users who want to access your apps. As part of the sign-up flow, you can provide options for different social or enterprise identity providers, and collect information about the user. Learn about [self-service sign-up and how to set it up](self-service-sign-up-overview.md).
 
 You can also use [API connectors](api-connectors-overview.md) to integrate your self-service sign-up user flows with external cloud systems. You can connect with custom approval workflows, perform identity verification, validate user-provided information, and more.
