Krom Automation Pro connects to WooCommerce Subscriptions, the official subscription add-on for WooCommerce. It gives you nine triggers covering every meaningful subscription lifecycle event — from creation and renewal through cancellation, expiry, payment failures, and trial endings — plus two actions for managing subscription status programmatically.

No API key or configuration is required. Krom Automation detects WooCommerce Subscriptions automatically when the plugin is active.

Requirements #

• Krom Automation Pro installed and activated
• WooCommerce installed and active
• WooCommerce Subscriptions installed and active

Available triggers #

Subscription Created

Fires when a new WooCommerce Subscription is created at checkout. This fires when the customer completes the purchase that sets up the subscription, not on each renewal.

Data field	Description
subscription_id	The subscription ID
status	Subscription status at creation (usually active or pending)
product_name	Name of the subscription product
recurring_amount	The recurring charge amount
billing_period	Billing period (month, year, etc.)
start_date	Subscription start date
customer_email	Customer email address

Common use: Sending a welcome email the moment a subscription starts, adding the customer to a subscriber-specific Mailchimp audience, or posting a new subscriber notification to Slack.

Subscription Renewed

Fires when a subscription renewal payment completes successfully.

Data field	Description
subscription_id	Subscription ID
renewal_order_id	The order ID of this specific renewal
product_name	Subscription product name
amount	Amount charged for this renewal
customer_email	Customer email address

Common use: Sending a renewal receipt to the customer, logging renewals to Google Sheets for revenue tracking, or notifying the team of successful recurring revenue.

Subscription Cancelled

Fires when a subscription status changes to cancelled. This fires whether the cancellation was requested by the customer or triggered administratively.

Data field	Description
subscription_id	Subscription ID
product_name	Subscription product name
customer_email	Customer email address
cancel_date	Date of cancellation

Common use: Triggering a win-back campaign immediately after cancellation, notifying the customer success team, or removing the customer from an active-subscribers email list.

Subscription Expired

Fires when a subscription reaches its end date and expires naturally. This is distinct from cancellation — expiry happens when the subscription’s scheduled end date arrives.

Data field	Description
subscription_id	Subscription ID
product_name	Subscription product name
customer_email	Customer email address
expiry_date	The date the subscription expired

Common use: Sending a renewal offer to the customer after expiry, removing access to subscriber-only content, or logging expired subscriptions for churn reporting.

Subscription On Hold

Fires when a subscription is paused and moved to on-hold status. This typically happens after a failed payment when WooCommerce Subscriptions sets the subscription to on-hold while awaiting retry.

Data field	Description
subscription_id	Subscription ID
product_name	Subscription product name
customer_email	Customer email address

Common use: Notifying the customer that their subscription has been paused, alerting the team to follow up, or starting a dunning sequence if the hold was caused by a payment failure.

Subscription Reactivated

Fires when a subscription returns to active status from on-hold or cancelled.

Data field	Description
subscription_id	Subscription ID
product_name	Subscription product name
customer_email	Customer email address

Common use: Sending a re-activation welcome back email, notifying the team that a previously cancelled customer has returned, or re-adding the customer to an active-subscriber audience in your email marketing platform.

Subscription Payment Failed

Fires when a scheduled subscription renewal payment fails. This is one of the most important triggers for subscription businesses — catching payment failures quickly and recovering them is directly tied to revenue retention.

Data field	Description
subscription_id	Subscription ID
product_name	Subscription product name
customer_email	Customer email address
amount	The amount that failed to charge

Common use: Triggering a multi-step dunning sequence — an immediate payment failure email, a follow-up 2 days later, and a final notice 5 days later before cancellation.

Subscription Trial Ending

Fires when a subscription trial period ends. Use this to contact customers before their trial converts to a paid subscription, giving them a chance to review their plan or take action.

Data field	Description
subscription_id	Subscription ID
product_name	Subscription product name
customer_email	Customer email address
trial_end_date	The date the trial period ends

Common use: Sending a “your trial is ending soon” reminder email a few days before the trial converts, prompting the customer to update payment details or upgrade to a higher plan.

Subscription Status Changed

Fires on any subscription status transition. This is the broadest subscription trigger — it catches every status change across all subscriptions. Use conditions on old_status and new_status to target specific transitions.

Data field	Description
subscription_id	Subscription ID
old_status	Status before the change
new_status	Status after the change
customer_email	Customer email address

Common use: When you need to respond to a specific transition that doesn’t have a dedicated trigger — for example, acting when a subscription moves from on-hold back to pending rather than directly to active.

Available actions #

Cancel WCS Subscription

Cancels a WooCommerce Subscription. By default, this sets the subscription to pending-cancel, which means the customer retains access until the current billing period ends. Set the immediate flag to cancel instantly.

Field	Description
subscription_id	The subscription ID to cancel. Use {{subscription_id}} from the trigger.
immediate	Toggle. When enabled, cancels the subscription immediately rather than at the end of the billing period.

Common use: Automatically cancelling a subscription after a set number of failed payment retries, or cancelling programmatically based on a condition such as a membership status change.

Change WCS Subscription Status

Sets a WooCommerce Subscription to any valid status without going through the cancellation flow.

Field	Description
subscription_id	The subscription ID. Use {{subscription_id}} from the trigger.
new_status	The target status: active, on-hold, cancelled, pending-cancel, expired, or pending.

Common use: Reactivating an on-hold subscription programmatically after a payment issue is resolved, or pausing a subscription based on an external event received via webhook.

Setting up a WooCommerce Subscriptions workflow #

1. Go to Krom Automation > Workflows and click Add New Workflow.
2. Click Add Trigger and select the relevant subscription trigger from the WooCommerce Subscriptions category.
3. For the Subscription Status Changed trigger, add a Condition node with old_status and new_status to target the specific transition you want.
4. Add your actions. Use {{subscription_id}}, {{customer_email}}, {{product_name}}, and {{recurring_amount}} as merge tags.
5. Simulate and activate.

Troubleshooting on WooCommerce subscriptions integration #

WooCommerce Subscriptions triggers aren’t appearing

Confirm WooCommerce Subscriptions is installed and active, not just WooCommerce. The subscription triggers only appear when both plugins are present and active.

Subscription Payment Failed is firing, but I also see Subscription On Hold firing

This is expected behaviour. When a payment fails, WooCommerce Subscriptions puts the subscription on hold. Both triggers fire. If you only want to respond to the payment failure specifically, use the Subscription Payment Failed trigger. If you want to respond to the hold regardless of its cause, use Subscription On Hold.

The Cancel WCS Subscription action isn’t cancelling immediately

By default the action sets the subscription to pending-cancel, which delays cancellation to the end of the billing period. Enable the immediate toggle if you need instant cancellation.
