## One Flow, for all Signups
Doesn't matter what language/buzzword or if the customer has signed up through **Mobile** or **Desktop.** In Chatarmin you can create ONE Flow with the Trigger **"Signed up for 'Back in Stock'":**
For all new Signups, the flow adds a Tag about the Product to their profile.
A Tag with the label "**BIS / Product X**" -> Whereas "Product X" is the product/variant name
So now you can even filter your audience based on that Tags
## One Flow, for all 'Back in Stock' Products
When choosing the Trigger **"Product is 'Back in Stock'"**
-> That Flow will listen for all the upcoming restocks and then trigger the Flow only for those, **who have signed up to that restocked Product**. Exactly for that, we have that unique Tag from their previous signup (mentioned above)
You can also customize when the **Back in Stock** notification is triggered, specifically in terms of the **quantity of products** that need to be back in stock before the notification is sent. You can adjust the settings in the **Back in Stock flow** so that the notification is only triggered when the **stock level reaches a minimum threshold** (e.g., 500 units). This ensures that the notification is sent only when there are enough items available, preventing messages from being sent prematurely due to small restocks (like a single returned item).
Since the Trigger can trigger for different Products, it also comes with "**Variables**" you can use for the Image or in Variables of a Template. So you can for example set the Image for a template like so:
