How do I find my Heap App ID and API Key?

Log in to Heap, go to **Account > Projects**, and select your project. Your **App ID** will be visible there. For the **API Key**, navigate to the API section in your project settings to generate a server-side key.

Can I track events server-side through this integration?

Yes! Use the `track_event` tool. You provide the user identity, event name, and optional properties. This is perfect for capturing actions that happen outside the client browser.

How do I update user properties in bulk?

Use the `bulk_add_user_properties` tool. You must provide a JSON array containing objects with `identity` and `properties` for each user you wish to update.

Is the data deletion tool permanent?

Yes. The `delete_user_data` tool triggers a permanent deletion of the user identity and all historical data from Heap, helping you comply with GDPR and CCPA requests.
