New Profound API Feature to Simplify HTTP Status Codes

Many times, you just need a simple API interface to return data.  Your API accepts input parameters, retrieves the data, and returns it with a simple status code 200.  But sometimes, you need a more sophisticated interface.  Perhaps you want to return status 204 to indicate that the request was successfully handled, but no matching data was found.  You can also return status 201 on a POST request to indicate that the new item was successfully created.  These are just a few of the possible HTTP status codes you might want to use in your API. 

Profound API has always had the ability to return different status codes with and output parameters needed, but it required using the Custom Node.js Code plugin in your low-code workflow.  These custom responses were not obvious to developers maintaining existing APIs and were not reflected in Profound API’s automatic Open API documentation, API Explorer. 

New HTTP Status Features

Profound API version 7 includes new features to integrate HTTP status code handling into its powerful low-code system.  These new features allow developers to have flexible API interfaces that make their APIs easier to use. 

Output Parameters by Status Code 

The first feature developers will notice after upgrading is the addition of HTTP Status Code controls on the Output Parameters tab in the Profound API IDE. 

HTTP status codes can be added, removed, and selected using these controlsEach status code defined for a route will have its own output parameter list independent of other status codesThis gives developers the ability to define the interface for each potential status code ahead of time, but only requires them to define the status codes that will be used. 

Set API Output Enhancement 

To allow easy use of these new output parameters by HTTP status, the Set API Output plugin in the Profound API low-code framework has been enhanced. 

As seen in the image above, a new drop down was added to the plugin to allow the developer to select what defined HTTP status they would like to returnWhen a status is selected, the output parameter list is automatically updated to the defined parameters for that status code.  This eliminates the need for custom code to manipulate HTTP status codes and parameters returned, which in turn makes it easy for future developers to follow your API’s workflow.

Improved API Documentation 

Profound API’s API Explorer is an Open API, or Swagger, based portal for documenting your APIs.  All APIs are automatically added to the portal and documented based on the definition of the API interface as defined by the developer in the Profound API IDE.  With the addition of HTTP status code support for defining output parameters in the IDE, these new definitions are pulled into the API Explorer automatically. 

As you can see, each defined status code is listed in the documentation with its corresponding output definitionBy properly documenting all possible API outputs, developers consuming your APIs can handle all possible results within their applications.
