Defining security scheme components
A security scheme component specifies all the settings for a particular aspect of API security; for example, the user registry that you use to authenticate access to the API.
You can complete this task either by using the IBM API Studio UI application, or by using the browser-based API Manager UI.
You can create security definitions of the following types:
| Type | Description |
|---|---|
| Basic authentication | Use a basic authentication security definition to specify a user registry or an authentication URL to be used to authenticate access to the API. |
| API key | Use an API key security definition to specify what application credentials are required to call an API. |
| OAuth2 | Use an OAuth2 security definition to specify settings for OAuth token based authentication for your API. |
| HTTP Bearer | Use an HTTP Bearer definition to specify how to validate the Bearer token that is required to call an API. |
