# WooCommerce Subscriptions: renewal scheduler

Use this when code touches renewal timing, scheduled payments, renewal order creation, or retry behavior. The key rule: change subscription dates/status through `WC_Subscription` methods, not by writing schedule meta or Action Scheduler rows directly.

## Misconception this skill corrects

> "To reschedule a subscription, update `_schedule_next_payment` or call `as_schedule_single_action()`."

That bypasses WCS validation and the scheduler's cleanup/reschedule behavior. `WCS_Scheduler` listens to `woocommerce_subscription_date_updated`, `woocommerce_subscription_date_deleted`, and `woocommerce_subscription_status_updated`. Those fire when you use `WC_Subscription::update_dates()`, `delete_date()`, or `update_status()`.

## When to use this skill

Trigger when ANY of the following is true:

- The user wants to change `next_payment`, `trial_end`, `end`, `payment_retry`, or renewal timing.
- Code contains `_schedule_next_payment`, `_schedule_payment_retry`, `as_schedule_single_action`, `woocommerce_scheduled_subscription_payment`, `WCS_Action_Scheduler`, `wcs_create_renewal_order`, or `WCS_Retry_Manager`.
- A gateway or integration needs to charge recurring payments, create renewal orders, react after a renewal succeeded, or handle failed renewal retries.

## Renewal flow

For a normal WCS-managed automatic renewal:

1. A future Action Scheduler action exists in group `wc_subscription_scheduled_event`.
2. The action hook is `woocommerce_scheduled_subscription_payment` with args `array( 'subscription_id' => $id )`.
3. `WC_Subscriptions_Manager::prepare_renewal()` runs at priority `1`. It puts the subscription on hold and creates a renewal order with `wcs_create_renewal_order()`.
4. `wcs_renewal_order_created` fires after the renewal relation is stored.
5. `WC_Subscriptions_Payment_Gateways::gateway_scheduled_subscription_payment()` runs at priority `10`.
6. For non-manual gateways that do not manage their own schedule, WCS triggers `woocommerce_scheduled_subscription_payment_{gateway_id}` with `$amount, $renewal_order`.
7. After payment result, use `woocommerce_subscription_renewal_payment_complete` or `woocommerce_subscription_renewal_payment_failed` for business side effects.

Do not fulfill, ship, grant service, or call an external "success" API on `woocommerce_scheduled_subscription_payment`; at that point the renewal may not be paid yet.

## Safe date changes

```php
$subscription = wcs_get_subscription( $subscription_id );

if ( ! $subscription instanceof WC_Subscription ) {
    return;
}

// UTC MySQL datetime. This updates WCS props, validates ordering, saves,
// and lets WCS_Action_Scheduler reschedule the matching action.
$subscription->update_dates(
    array(
        'next_payment' => '2026-05-15 10:00:00',
    ),
    'gmt'
);
```

Use these date keys:

| Date type | Meaning | Scheduled hook |
|---|---|---|
| `next_payment` | Next renewal payment due date | `woocommerce_scheduled_subscription_payment` |
| `trial_end` | Trial expiry | `woocommerce_scheduled_subscription_trial_end` |
| `end` on active subscription | Subscription expiration | `woocommerce_scheduled_subscription_expiration` |
| `end` on `pending-cancel`/`cancelled` | End of prepaid term | `woocommerce_scheduled_subscription_end_of_prepaid_term` |
| `payment_retry` | Retry for last renewal order | `woocommerce_scheduled_subscription_payment_retry` |

`update_dates()` is strict. It throws if a date is invalid or out of order. If you are importing messy external data and want to keep valid values while ignoring invalid ones, use `update_valid_dates()` and still catch exceptions for impossible ordering.

```php
try {
    $subscription->update_valid_dates( $dates, 'gmt' );
} catch ( InvalidArgumentException $e ) {
    wc_get_logger()->warning( $e->getMessage(), array( 'source' => 'myplugin-subscriptions-import' ) );
}
```

## Force a renewal safely

Prefer triggering WCS's normal scheduled-payment action when you want "run the renewal flow now":

```php
$subscription = wcs_get_subscription( $subscription_id );

if ( $subscription instanceof WC_Subscription && $subscription->has_status( 'active' ) ) {
    do_action( 'woocommerce_scheduled_subscription_payment', $subscription->get_id() );
}
```

This uses the same flow as the scheduled action: status handling, renewal order creation, and gateway hook dispatch. If you only need to create a pending renewal order for later payment, call `wcs_create_renewal_order()` directly:

If the payment method supports `gateway_scheduled_payments`, the gateway owns its own recurring schedule and WCS will not create/charge the normal renewal order from this hook.

```php
$renewal_order = wcs_create_renewal_order( $subscription );

if ( is_wp_error( $renewal_order ) ) {
    wc_get_logger()->error( $renewal_order->get_error_message(), array( 'source' => 'myplugin-renewals' ) );
    return;
}

$renewal_order->update_meta_data( '_myplugin_external_id', $external_id );
$renewal_order->save();
```

When decorating renewal orders, `wcs_renewal_order_created` is usually better than wrapping `wcs_create_renewal_order()` everywhere:

```php
add_filter( 'wcs_renewal_order_created', function ( WC_Order $renewal_order, WC_Subscription $subscription ): WC_Order {
    $renewal_order->update_meta_data( '_myplugin_subscription_source', $subscription->get_id() );
    $renewal_order->save();

    return $renewal_order;
}, 10, 2 );
```

## Gateway recurring charge hook

Payment gateways that charge WCS-managed renewals should hook the gateway-specific dynamic action:

```php
add_action( 'woocommerce_scheduled_subscription_payment_my_gateway', function ( $amount, WC_Order $renewal_order ): void {
    $subscription_ids = wcs_get_subscription_ids_for_order( $renewal_order, 'renewal' );

    // Charge the saved token. On success call $renewal_order->payment_complete().
    // On failure call $renewal_order->update_status( 'failed', ... ).
}, 10, 2 );
```

The suffix is the payment method ID stored on the renewal order. Do not use the old `scheduled_subscription_payment_{gateway}` hook; WCS keeps compatibility shims, but new code should use the `woocommerce_` hook.

## Correct success/failure hooks

| Need | Hook | Args |
|---|---|---|
| Provision after any subscription payment | `woocommerce_subscription_payment_complete` | `WC_Subscription $subscription` |
| Provision after renewal payment only | `woocommerce_subscription_renewal_payment_complete` | `WC_Subscription $subscription, WC_Order $last_order` |
| React to any payment failure | `woocommerce_subscription_payment_failed` | `WC_Subscription $subscription, string $new_status` |
| React to renewal payment failure | `woocommerce_subscription_renewal_payment_failed` | `WC_Subscription $subscription, WC_Order $related_order` |
| Customer paid a failed renewal | `woocommerce_subscriptions_paid_for_failed_renewal_order` | `WC_Order $renewal_order, WC_Subscription $subscription` |

## Retry flow

WCS retries are their own objects/rules. Do not reschedule retries by hand unless replacing the retry system.

| Need | Hook/filter | Use |
|---|---|---|
| Toggle retry feature | `wcs_is_retry_enabled` | Disable/enable retry handling. |
| Change retry cadence | `wcs_default_retry_rules` | Replace default rules array. |
| Modify a specific retry | `wcs_get_retry_rule_raw` or `wcs_get_retry_rule` | Customize by retry number/order. |
| Before/after retry rule applied | `woocommerce_subscriptions_before_apply_retry_rule`, `woocommerce_subscriptions_after_apply_retry_rule` | Observe creation of retry schedule. |
| Before/after retry payment | `woocommerce_subscriptions_before_payment_retry`, `woocommerce_subscriptions_after_payment_retry` | Wrap the actual retry attempt. |

`wcs_is_scheduled_payment_attempt` is a filter around WCS's internal `doing_action()` check, not a public getter. If your own code needs to know whether it is inside a scheduled payment attempt, check the actions directly:

```php
add_filter( 'woocommerce_email_enabled_customer_processing_renewal_order', function ( bool $enabled ): bool {
    if ( doing_action( 'woocommerce_scheduled_subscription_payment' ) || doing_action( 'woocommerce_scheduled_subscription_payment_retry' ) ) {
        return false;
    }

    return $enabled;
} );
```

Only hook `wcs_is_scheduled_payment_attempt` when you intentionally need to override WCS retry detection.

## Scheduler customization

Only use these when you intentionally extend WCS scheduling. For ordinary next-payment changes, use `update_dates()`.

```php
add_filter( 'woocommerce_subscriptions_date_types_to_schedule', function ( array $date_types ): array {
    $date_types[] = 'myplugin_followup';
    return array_unique( $date_types );
} );

add_filter( 'woocommerce_subscriptions_scheduled_action_hook', function ( string $hook, string $date_type ): string {
    return 'myplugin_followup' === $date_type ? 'myplugin_subscription_followup' : $hook;
}, 10, 2 );

add_action( 'myplugin_subscription_followup', function ( int $subscription_id ): void {
    $subscription = wcs_get_subscription( $subscription_id );
    if ( $subscription instanceof WC_Subscription ) {
        myplugin_send_followup( $subscription );
    }
} );
```

If you change scheduled args with `woocommerce_subscriptions_scheduled_action_args`, keep them deterministic. WCS uses the args to find and unschedule existing actions.

## Common mistakes

```php
// WRONG: bypasses WCS date validation and Action Scheduler cleanup.
update_post_meta( $subscription_id, '_schedule_next_payment', '2026-05-15 10:00:00' );

// RIGHT:
$subscription = wcs_get_subscription( $subscription_id );
$subscription->update_dates( array( 'next_payment' => '2026-05-15 10:00:00' ), 'gmt' );

// WRONG: create a duplicate AS action with different args/group.
as_schedule_single_action( time() + DAY_IN_SECONDS, 'woocommerce_scheduled_subscription_payment', array( $subscription_id ) );

// RIGHT: set the subscription date and let WCS schedule the canonical action.
$subscription->update_dates( array( 'next_payment' => gmdate( 'Y-m-d H:i:s', time() + DAY_IN_SECONDS ) ), 'gmt' );

// WRONG: fulfillment at scheduled-payment time, before payment succeeds.
add_action( 'woocommerce_scheduled_subscription_payment', 'provision_customer' );

// RIGHT:
add_action( 'woocommerce_subscription_renewal_payment_complete', 'provision_customer_after_renewal', 10, 2 );
```

## What this skill does NOT cover

- Building the full gateway tokenization/payment-method-change UI.
- General HPOS compatibility for raw order queries. Use `wc-hpos-compatibility`.
- A complete hook catalog. Use `wcs-subscription-hooks` for broader hook selection.

## Cross-references

- Run `wcs-subscription-hooks` when you need a broader action/filter map beyond renewal timing.
- Run `wc-hpos-compatibility` before writing SQL or `WP_Query` over subscriptions/orders.
