Power Automate: Apply to each Action
Loops through an array. Use item() to reference each element.

Reference
This is my reference library, the place I send people when they need precise, dependable answers about how a specific function, action, or trigger actually behaves. Tutorials teach you a workflow, but a reference tells you exactly what a piece does, what it expects, and where it bites. My Excel Function Reference breaks down worksheet functions like the "Count" function with clear syntax and examples. The Power Apps Function Reference covers the Power Fx functions you use to build canvas apps, and the SharePoint List Function Reference explains the calculated column functions that shape list data. For automation, the Power Automate Trigger Reference documents how each trigger fires, while the N8N Node Reference and N8N Trigger Reference do the same for the open-source world. An OData Reference handles the query syntax for filtering and sorting data. Every page delivers real syntax, real parameters, and the gotchas I have hit.
