# In-app purchase actions

{% hint style="warning" %}
The workflow events in this section only apply to native mobile apps.
{% endhint %}

#### **Initiate subscription purchase**

Starts a native in-app purchase flow for a selected billing variant.

Key behaviors:

* Opens the Apple or Google payment sheet
* Handles receipt validation automatically
* Updates the Subscription Purchases table when the purchase completes

You can select a billing variant directly or pass one dynamically, such as from a repeating group.

A typical flow looks like this:

* The user taps an *Upgrade* or *Subscribe* button
* The workflow runs *Initiate subscription purchase*
* Bubble hands off to Apple or Google
* The subscription state updates automatically

{% hint style="warning" %}
**Important:** A User must be logged into an account on your app in order to initiate a purchase as a Subscription Purchase record must be linked to a User. Hide all billing actions until a user has logged in.
{% endhint %}

#### **Manage subscription**

Redirects the user to the platform-native subscription management screen.

Use this action to allow users to:

* Cancel a subscription
* Change billing frequency
* Upgrade or downgrade within a subscription group

Apple and Google control the management UI. Bubble provides the entry point, not the management controls themselves.

{% hint style="warning" %}
**Note:** Users can also upgrade or downgrade by initiating a purchase on a different plan for upgrades, downgrades, and cross-grades.
