Supported HTTP Methods

The most commonly used HTTP methods (or verbs) are GET, POST, PATCH,PUT, DELETE, and OPTIONS. The building blocks of REST APIs, these methods define actions applied to REST resources using their URLs.

Note:

• Oracle recommends that you periodically review if your REST request requirements have changed. Also check with your service administrator if any capacity adjustments or other changes are required in your service configuration.
• Child resources usually inherit security privileges from their parent resource. Therefore, to use a method on a child resource, you may need to have access to use that method on the parent resource. However, there may be some child resources with different privilege requirements to access them.

The following table lists the methods and their scope for singular and collection resources.

Method	Works with a Singular Resource?	Works with a Collection Resource?
GET	Yes. Gets a single resource.	Yes. Gets a subset, or all of the resources in the collection.
POST	Yes. Creates a single resource.	Yes. Creates a new resource in the collection.
PUT	Yes. Updates a resource.	No.
PATCH	Yes. Replaces objects related to a resource.	No.
DELETE	Yes. Deletes a resource.	No.
OPTIONS	Yes. Gets the supported methods for a resource.	No.
