How to Expose a REST API

REST APIs allow you to expose data and functionality of your application over HTTP to be used by other systems.

Each REST API method of this project illustrates one or two use cases of how you can use expose REST APIs. Check how to:

Expose a method to provide data

- In the method, set the 'HTTP method' property to GET;
- Add a Contact List as output parameter;
- Set the placement of the output in the request at the 'Send In' property of the parameter.

Expose a method to create data

- In the method, set the 'HTTP Method' property to POST;
- Add a Contact as input parameter, and a Contact Identifier as output parameter;
- Set where the input parameter is received in its 'Receive In' property;
- Set where the output parameter is sent in its 'Send In' property.
 

Expose a method to update data

- In the method, set the 'HTTP method' property to PUT;
- Add a Contact as input parameter;
- Set the placement of the input in the request at the 'Receive In' property of the parameter.
 

Expose a method to delete data or raise an error

- In the method, set the 'HTTP method' property to DELETE;
- Add a Contact Identifier as input parameter;
- Set the placement of the input in the request at the 'Receive In' property of the parameter;
- In the method logic, raise a custom error using the Raise Error element if there is any problem with deleting this record.
 

Add Basic authentication to an exposed REST API

The action calls the User_Login action of the Users module.
If the authentication succeeds, the invoked REST API method is executed immediately after.
Otherwise, an exception is raised, the request is aborted, and the response returns a security error.
