# How can I push user events?

**If you are using Crisp on a website where users are authenticated, you may want to push events to retarget them later on different channels. Using Crisp, you can push events in two different ways: through the JS SDK and through the chatbot**

This method uses the Crisp JavaScript API, that you can call from your own code or you can use the chatbot to trigger an event.

|| You can push an event from your backend too using our API, here is [an article that explains everything about it](/en/article/how-to-push-user-event-from-my-backend-z0tda4/).

**Here's how you would proceed to push an event using the JS SDK:**

```
// Feed this call with your own events data.
$crisp.push(["set", "session:event", [[
    ["product_bought", { price: "$200", name: "iPhone 6S" }, "red"]
]]]);
```

Sets one or multiple session events, with a text and an optional data object and **optional color** (in `red`, `orange`, `yellow`, `green`, `blue`, `purple`, `pink`, `brown`, `grey`, `black`)`

|| Of course, you need to replace **product_bought** with your own event name, own data and own color. For instance, you can use **login** or **signup**, **upgrade**, etc.

**Here's how you would proceed to push an event using the chatbot:**

So the chatbot offers different blocks that have specific behaviors. One of them makes you able to push an event to trigger a campaign. The one we're looking for is the "Push session event" block, which is an action block.

**Use cases for pushing an event through the bot:**

* Automate email sequences following a product info request  
* Send a calendly link based on information granted through the bot  
* Push Knowledge Base articles from customers' input

||| Events are used for automation purpose, and must not serve as a permanent database of data. We only retain the most recent events for your users. If you need to store per-user data permanently, please use [custom user data](/en/article/how-can-i-automatically-set-custom-data-1xh7pqk/) instead.
