# Activity: Save State

Save State is a campaign flow step used to **capture and store dynamic data at a specific moment**. Once saved, this data becomes accessible throughout the rest of the flow and can be reused for logic checks, personalization, or tag replacement inside creatives.

When triggered, Save State stores the current value of a property - whether it's a campaign-triggered value (like Bonus Amount, Casino Bet) or a user attribute (such as First Deposit Date, Registration Date, or Language). These saved values can then be referenced using tags like {{campaign.xxx}}, allowing operators to inject them into assets, communications, or conditional logic.

{% hint style="warning" %}
Campaign tags can't be used in Java Script functions, only public tags (markers) can.
{% endhint %}

Save state is especially useful when you need to preserve a value at a specific point in time and ensure consistency across later stages of the campaign, even if the original source changes.

### Use case scenario

There are many cases when the campaign starts on some particular action but the communication about it only comes way later. Let’s say the campaign starts on a minigame win, and then you want to use the name of the minigame prize won in the communication to users. But first you need to check for the preferred communication method, unsubscription, etc. So there’s bound to be at least one step between the campaign start and the communication sendout. And to enable the usage of a dynamic property “Minigame: prize name“ - we can use the “save state” step.
