How to expose apex classes as REST Web Services?

How to expose apex classes as REST Web Services?

You can expose your Apex classes and methods so that external applications can access your code and your application through the REST architecture. This is an overview of how to expose your Apex classes as REST web services.

Why is it important to version Your REST API?

REST API Versioning. To manage this complexity, version your API. Versioning helps you iterate faster when the needed changes are identified. Change in an API is inevitable as your knowledge and experience of a system improve. Managing the impact of this change can be quite a challenge when it threatens to break existing client integration.

Which is the default format for Apex Rest?

Is it safe to expose data with Apex Rest?

Developers who expose methods using the Apex REST annotations should therefore take care that they are not inadvertently exposing any sensitive data. Apex class methods that are exposed through the Apex REST API don’t enforce object permissions and field-level security by default.

What’s the difference between soap and REST Web Services?

When you want to expose a new service, you have to make a decision between 2 standards: SOAP or REST. SOAP stands for Simple Object Access protocol.

What do you need to know about apex?

Apex provides two data structures and a method for sObject and field describe information: Token —a lightweight, serializable reference to an sObject or a field that is validated at compile time. This is used for token describes. The describeSObjects method—a method in the Schema class that performs describes on one or more sObject types.

Can you create an approval process in apex?

You can not create approval process or workflow with Apex system classes. These are configurable business logics which can not be created generally in Apex. But there is one way of creating these components is Metadata API.

What happens when Apex Rest has no parameters?

If the Apex method has no parameters, Apex REST copies the HTTP request body into the RestRequest.requestBody property. If the method has parameters, then Apex REST attempts to deserialize the data into those parameters and the data won’t be deserialized into the RestRequest.requestBody property.

How to create httppost method in API controller?

The Controller looks like the following: public class VTRoutingController : ApiController { [HttpPost] public MyResult Route (MyRequestTemplate routingRequestTemplate) { return null; } [HttpPost] public MyResult TSPRoute (MyRequestTemplate routingRequestTemplate) { return null; } }

How to retrieve the body of an apex request?

You can retrieve the body as a Blob from the HttpRequest object if there are no parameters to the Apex method. If parameters are defined in the Apex method, an attempt is made to deserialize the request body into those parameters. If the Apex method has a non-void return type, the resource representation is serialized into the response body.

How is rest resource used in tooling API?
