Auth0 exposes two APIs for developers to consume in their applications:
Authentication: Handles identity-related tasks;
Management: Handles management of your Auth0 account, including functions related to (but not limited to):
The Authentication API exposes Auth0 identity functionality, as well as those of supported identity protocols (such as OpenID Connect, OAuth, and SAML). Typically, you would consume this API through one of the Auth0 SDKs, such as Auth0.js, or a library, like Lock. If you are building your authentication UI manually, you would need to interface directly with the Authentication API.
Management API v2
The Management API allows you to manage every aspect of your Auth0 account. For example, you can use the Management API to automate the configuration of your user environments or for runtime tasks such as user creation.
Management API v1 - DEPRECATED
The Management API v1 is deprecated and should not be used for new projects. If your existing application uses Management API v1, you can reference its API explorer here.
