# Functions FAQ ### **Is there an additional cost for Functions?** Nope! Functions is included functionality. Contact our team at to gain access. ### **Hosting the source code** **Is there a way to connect a private repository? Or does it have to be a public repo? Are there methods other than GitHub?** Right now, we only support public repos on GitHub. ### **Updating / Maintaining** #### Is there a way to guarantee that the Function is using the latest version of the source code? There's a "refresh" button in the UI that will pull the latest version of the code. ### **Development** #### When iterating and testing a function, what's the best way to get feedback / validate that it's working? Set up a development environment in Freshpaint, and upload the function there. Send events to the development environment and to confirm that they are working properly. [Pipedream](https://pipedream.com/) is also a helpful tool for ensuring that requests are being formatted properly. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
