Many Action Nodes could be featured, but in this Topic we focus on those we find most useful for many use cases, and that could require some examples in order for you to see the possibilities or to make them work as intended. ### Update Object Update Object is used for updating properties of Data Sources or App Variables. You may use Update Object to update a single Object, or to batch update multiple objects. We recommend reading our documentation on Batch Update found [here](/library/action-nodes/update-object.md#batch-update). ### Read Objects When using Database Connected Data Sources, you do not need to use Read Objects, since the data is automatically read. But in many cases, you may want to e.g. read data into a Runtime Only data source. Read Objects allows you to read *from another Data Source*, or *from the Database directly*. We recommend reading our documentation found [here ](/library/action-nodes/read-objects.md)if you are unfamiliar with these concepts, or if you want to understand the settings of the Read Objects Action Node. ### Open Confirm Dialog Open Confirm Dialog is an Action Node that offers a built-in (modal) dialog for prompting the user. It is typically used for collecting confirmation from the user before e.g. some data is to be deleted (non-reversible operations). * Example in our [Showroom](https://showroom.appfarm.app/action-nodes/open-confirm-dialog) * Read our [Documentation](/library/action-nodes/open-confirm-dialog.md) ### Import Data You may import data from CSV files using the Import Data Action Node. * Example in our [Showroom](https://showroom.appfarm.app/action-nodes/import-data) * Read our [Documentation](/library/action-nodes/import-data.md) --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.appfarm.io/appcademy/appfarm-fundamentals/actions-and-logic-fundamentals/featured-action-nodes.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
