Luklak provides a rich library of actions, from simple data updates to complex integrations with external systems. This guide serves as a comprehensive reference for everything your automations can do. ## 1. Object & Data Manipulation These actions directly create or modify your `🧊 Objects` and their data. They are the most common building blocks for internal process automation. * **Create new Object:** Create a new standard `🧊 Object` or `🧊 Sub-Object` in any `Function`. * **Update data fields:** Modify the value of one or more fields on the triggering `🧊 Object` or a related `Object`. * **Transition status:** Move an `🧊 Object` to a new `Status` in its workflow. * **Increment/decrement number:** Increase or decrease the value of a number field by a specific amount, perfect for counters or inventory management. * **Create checklist:** Dynamically generate a list of checklist items inside an `🧊 Object`. * **Create connection between Objects:** Establish a defined `Global Connection` between two `🧊 Objects`. ## 2. Communication & Notification These actions send messages and alerts to both internal users and external contacts, ensuring the right people have the right information at the right time. ### Internal Messaging * **Send Private Message:** Send a direct message to a specific user's `Unified Inbox`. * **Post in Space Chat:** Post a message in the group chat of a `⏹️ Space` for all members to see. * **Post in Object Chat:** Send a message directly to a specific `🧊 Object`'s chat feed, keeping the conversation in context. ### External Communication * **Send Email:** Send customized emails to users or external addresses, using `Smart Values` to personalize the subject and body. * **Send Zalo ZNS:** Send template-based notification messages to phone numbers via Zalo's official ZNS service. * **Initiate VOIP Call:** Trigger a call to a phone number stored in a field. This is often used as a manual `Object Action` for sales or support teams to quickly connect with customers. ## 3. User & System Interaction This category covers special actions that interact directly with the user or system processes. * **Show Input Screen:** A special action tied to `Workflow Triggers`. When a user changes an `🧊 Object`'s status, this action can prompt them with a form to fill in required data before the transition is allowed to complete. ## 4. External Integrations These actions allow Luklak to communicate with the outside world, acting as the central hub for your entire tool stack. Push data from a Luklak `🧊 Object` to any external system that has a webhook or API endpoint. This is the universal tool for custom integrations. Generate payment links and QR codes, and automatically process incoming payment webhooks from Sepay to update the payment status on an `🧊 Object`. Connect to workflow automation platforms like n8n via Webhooks. This unlocks thousands of pre-built connectors to popular apps, enabling near-universal connectivity. ## What's Next? You've seen the vast library of actions your digital workforce can perform. The key to making these actions truly intelligent is to populate them with dynamic data from your `🧊 Objects`. * [**Learn how to use dynamic data: A Guide to Smart Values**](/en/02-platform/platform-overview/universal-automation/smart-values) * [**Return to the Automation Overview**](/en/02-platform/platform-overview/universal-automation)
