+title: getMacroIds()
+---
+
+Retrieve data for macro IDs generated via [`generateMacroIds()`](/reference/store-methods/generatemacroids) and stored
+via [`storeMacroIds()`](/reference/store-methods/storemacroids).
+
+## Signature
+
+```mjs
+Object store.getMacroIds(
+  String id,
+  macro = store.activeMacro,
+  part = store.activePart,
+)
+```
+
+The method takes an id and retrieves the data stored under the macro IDs for the active macro and active part.
+
+Or, if you want to, you can pass in `macro` and `part` to not use the active macro or part.
+
+## Example
+
+```mjs
+const ids = store.getMacroIds('macroId')
+```
+
+It is a best practice to return the result of this method from your macro.
