We have already seen an example of HTTP endpoint called greetUser(), which covers most of the essential parts of HTTP endpoints. There's just one important point to note, that we should always terminate our functions properly; else, they might continue to run, and the system will forcibly terminate it. We can end our function with send(), redirect(), or end().

Consider this example:

response.send("Welcome to the Cloud Function");

Also, if you are using Firebase hosting and want to connect your HTTP endpoint with some custom domain, you can do that as well.
