SwftDrops

Timed product drops for WooCommerce. Schedule a product release with a countdown, control access via waitlist or exclusive link, and route buyers straight to Swft Checkout when the drop goes live.

What it does

• Schedule a drop date and time per product
• Show a countdown timer on the product page before the drop
• Optional waitlist — customers register their email, receive a notification when the drop goes live
• Optional exclusive link — only customers with the link can add to cart
• Integrates with Swft Checkout: the checkout redirect happens immediately so buyers land on a pre-loaded checkout page, not a loading spinner

Installation

1. Download swft-drops.zip from swft.co.uk/modules
2. Install and activate
3. Go to WooCommerce → Settings → SwftDrops to configure global settings

Configuration

Global settings

Setting	Option	Default
Countdown style	swft_drops_countdown_style	clock (clock or text)
Waitlist enabled	swft_drops_waitlist_enabled	yes

Per-product settings

Edit any product and find the SwftDrops panel in the product data tabs:

Field	Key	Description
Drop date/time	_swft_drop_datetime	UTC datetime string
Exclusive link token	_swft_drop_token	Random token appended to product URL for access control
Notify waitlist	_swft_drop_notify_waitlist	Whether to email the waitlist when the drop opens

Extension data

SwftDrops adds the following to extensions.drops in the session when the cart contains a drop product:

{
  "drop_id": 1042,
  "product_id": 456,
  "drop_name": "Summer Drop 01",
  "dropped_at": "2026-06-01T12:00:00Z"
}

Available in the checkout frontend via:

window.SwftCheckout.getExtension('drops')

Order meta

Meta key	Value
_swft_ext_drops	Full drop data as JSON
_swft_drop_id	Drop ID for easy querying

Events fired

SwftDrops fires one additional event on the product page (not in the checkout):

document.addEventListener('swftdrops:live', (e) => {
  console.log(`Drop ${e.detail.dropId} is now live`)
  // e.detail: { dropId: number, productId: number }
})

This fires when the countdown reaches zero and the product becomes purchasable.

PHP hooks

// Modify the extension data
add_filter( 'swft_drops_extension_data', function( array $data, int $product_id ): array {
    return $data;
}, 10, 2 );

// Fire after a drop goes live (useful for sending waitlist notifications)
add_action( 'swft_drops_went_live', function( int $drop_id, int $product_id ): void {
    // e.g. send push notifications
}, 10, 2 );

// Filter the waitlist notification email
add_filter( 'swft_drops_waitlist_email', function( array $email, int $drop_id ): array {
    return $email;
}, 10, 2 );
