Welcome to the forum @fangfang94

Why don't you just put the whole object in flow memory, then you can get at any of the properties any time you like?

You can use Object.keys() in a function node [Object.keys() - JavaScript | MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys)  
Or  
In a change node $keys() using a JSONata expression [Object functions · JSONata](https://docs.jsonata.org/object-functions#keys)
