Get IAP Canceled Subscription List (iOS)

Guide for implementing a workflow in Bubble.io to retrieve a list of canceled In-App Purchase (IAP) subscriptions when a user triggers an event.

---

Overview

This guide walks you through setting up a Bubble.io workflow to fetch canceled In-App Purchase (IAP) subscription data from an iOS app using the "webtonative" plugin. The process triggers when a user interacts with a button (e.g., "Get IAP Canceled Sub"), initiates a search for canceled subscriptions, and retrieves the results for display or further use. This is ideal for managing subscription statuses in your app.

Prerequisites

• Bubble.io Account: An active Bubble.io account with a project.

• webtonative Plugin: Installed in your Bubble editor (available under Plugins).

• Apple Developer Account: Required for iOS testing via TestFlight (optional for initial setup).

• Basic Workflow Knowledge: Familiarity with Bubble’s workflow editor.

Step 1: Set Up the Trigger

• Purpose: Define the event that starts the process (e.g., a button click).

• Instructions:

  1. Open your Bubble editor and navigate to the page where you want this feature.

  2. You can add a button element (e.g., name it "Button Get IAP Canceled Sub") via the "Design" tab.

  3. Select the button, then click "Start/Edit Workflow" to open the workflow editor.

  4. In the "When" section, choose "When the Button Get IAP Canceled Sub is clicked."

     • This links the workflow to the button click action.

Step 2: Initialize the Canceled Subscriptions Check

• Purpose: Begin the process of querying canceled subscriptions using the webtonative plugin.

• Instructions:

  1. Click "Click here to add an event..." below the trigger in the workflow editor.

  2. Select "Plugins" > "webtonative - Init IAP Canceled Subscriptions (iOS)" from the dropdown.

     • This action prepares the iOS app to start retrieving canceled subscription data.

  3. Leave the default settings (no parameters needed unless specified by the plugin).

Step 3: Schedule a Delayed Check

• Purpose: Allow a brief delay (1 second) to ensure the initialization completes before fetching results.

• Instructions:

  1. After the "Init IAP Canceled Subscriptions" action, click "Click here to add an action..."

  2. Choose "Schedule API Workflow" > "Schedule get IAP Canceled Subs after 1 second."

     • Set the custom event to "get IAP Canceled Subs."

     • This delays the next step to give the system time to process.

Step 4: Define the Custom Event to Get Canceled Subscriptions

• Purpose: Execute the action to retrieve the canceled subscription data.

• Instructions:

  1. In the workflow editor, locate or create the "get IAP Canceled Subs" custom event.

  2. Click "Click here to add an event..." and select "Plugins" > "webtonative - Get IAP Canceled Subs (iOS)."

     • This fetches the list of canceled subscriptions.

  3. Configure the action:

     • Secret: Enter your App Store shared secret (e.g., vs234bd34f404fd31bd2ac22)

     • Is Test: Set to "Yes" for testing purposes.

     • Receipt Data: Check this option to include subscription receipt details.

Step 5: Retrieve Transaction Data

• Purpose: Extract and inspect the transaction data associated with canceled subscriptions (for testing or debugging).

• Instructions:

  1. After the "Get IAP Canceled Subs" action, click "Click here to add an action..."

  2. Select "Plugins" > "webtonative - Grab IAP Transaction Data (only for checking)."

     • This pulls detailed transaction data, such as whether a subscription was already purchased or canceled.

  3. The result will be available as "Result of step 1 (webtonative - Get...)" with fields like "success" and "message."

Step 6: Display Results for Testing

• Purpose: Show the retrieved data as an alert to verify the workflow works (optional).

• Instructions:

  1. After the "Grab IAP Transaction Data" action, click "Click here to add an action..."

  2. Choose "Show an alert" or "Display data."

     • Set the content to "Result of step 1 (webtonative - Get...)" > "message" to display the result (e.g., "Is Already Purchased" or "success").

  3. Set "Only when" to "Click" to trigger on the button press.

     • Note: This step is for testing only. In a live app, you might save the data to a database or display it in a list.

Note: Whenever a user triggers the action to get canceled subscriptions, it will always provide a list of all canceled subscriptions.

Testing and Deployment

• Testing:

  • Use the "Is Test" option and deploy to TestFlight for iOS testing.

  • Verify that the alert displays the expected data (e.g., canceled subscription details).

• Production:

  • Replace the alert with actions to save data to your Bubble database (e.g., create a "Canceled Subs" data type).

  • Remove testing flags and ensure the plugin is configured for live use.

Troubleshooting

• No Data Returned: Check the "Secret" key and ensure the webtonative plugin is properly set up.

• Errors: Review the plugin documentation or the Bubble community for support.
