Not really. In this [example](https://internetcomputer.org/docs/current/developer-docs/smart-contracts/advanced-features/serving-http-request#additional-examples) listed on the website, they mention an example, but it leads to a 404. Today, someone posted a similar [question](https://forum.dfinity.org/t/post-request-return-error-response-verification-failed/36582) on the forum, where they encountered an error related to certification. Perhaps someone could share a working example.
