# Custom Events

Send any event that matters to your product - a button tap, a feature being used, a form submitted. You define the name and the attributes.

UserSDK.default?.sendEvent(with: "subscription_started", params: [
    "plan": "pro",
    "billing_cycle": "annual",
    "price": 99.99
]) { success, error in
    if let error {
        // handle error
    }
}

The params dictionary is optional. If you don't need attributes, pass an empty dictionary:

UserSDK.default?.sendEvent(with: "onboarding_completed", params: [:])

The completion handler is also optional - omit it if you don't need to react to the result:

UserSDK.default?.sendEvent(with: "settings_opened", params: [:])
