Appstle Subscription Integration

Automatically update delivery dates when Appstle subscription billing succeeds.

Integrate Appstle Subscriptions with Bird Pickup & Delivery using Shopify Flow to automatically increment delivery dates for recurring orders. When a subscription billing cycle completes successfully, the workflow updates the next delivery date based on the subscription interval.

This integration requires Appstle Subscriptions, Shopify Flow, and a Bird Essential plan or above.

How It Works

Customer places a subscription order with a delivery date
Appstle processes the recurring billing
When billing succeeds, Shopify Flow triggers
Bird's Increment delivery date action updates the order's delivery date
The next delivery is automatically scheduled based on the subscription interval

Prerequisites

Before setting up this integration:

Install and configure Appstle Subscriptions app
Enable the Shopify Flow integration in Bird Settings
Ensure your Bird plan is Essential or above

Setup Guide

Step 1: Create a New Workflow

Go to Shopify admin > Shopify Flow app
Click Create workflow

Step 2: Add the Appstle Trigger

Click Select a Trigger
Search for "Appstle Subscription"
Select "Subscription Billing Success"

Step 3: Add the Bird Action

Click Then to add an action
Search for "Bird Pickup Delivery"
Select "Increment delivery date"

Step 4: Configure the Action

Click the Increment delivery date action node and configure:

Field	Value
Order	Select order.id from the trigger variables
Delivery interval count	Add variable `{{deliveryIntervalCount}}` or enter a number (e.g., `1`)
Delivery interval	Add variable `{{deliveryInterval}}` or enter the interval type (e.g., `Monthly`, `Weekly`)
App Name	Enter `Appstle` to identify the trigger source in logs

Your workflow is now active. Delivery dates will automatically update when subscription billing succeeds.

Understanding the Variables

Variable	Description	Example
`{{deliveryIntervalCount}}`	Number of intervals between deliveries	`1`, `2`, `3`
`{{deliveryInterval}}`	Type of interval	`Weekly`, `Monthly`, `Yearly`
`order.id`	The Shopify order ID	`gid://shopify/Order/12345`

Example Scenarios

Weekly Subscription:

deliveryIntervalCount: 1
deliveryInterval: Weekly
Result: Delivery date moves forward by 1 week

Bi-Weekly Subscription:

deliveryIntervalCount: 2
deliveryInterval: Weekly
Result: Delivery date moves forward by 2 weeks

Monthly Subscription:

deliveryIntervalCount: 1
deliveryInterval: Monthly
Result: Delivery date moves forward by 1 month

Troubleshooting

Delivery Date Not Updating

Verify the Shopify Flow workflow is turned on
Check that the order.id variable is correctly mapped
Ensure the Bird Shopify Flow integration is enabled in Bird Settings
Confirm your Bird plan is Essential or above

Incorrect Date Calculation

Verify the deliveryIntervalCount and deliveryInterval values match your Appstle subscription settings
Check if you're using Appstle variables or static values

Workflow Not Triggering

Verify Appstle is correctly configured and billing is processing
Check Shopify Flow run history for errors
Ensure the trigger is set to "Subscription Billing Success"
