Summary

Our Post API is now a complete feature. If a developer wants, they can create a desktop or mobile application using this API, all without using HTML scraping, which is a very tedious and long process. Giving the developers who wish to use your website as a platform the ability to do so will increase your site's popularity, as they will essentially give you free advertising with their app or website.

In the next chapter, we will use the popular program Celery to run programs and tasks asynchronously with our application.
