X-API-Key: your_api_key_here

Request Body

Parameter	Type	Required	Default	Description
`order_ids`	string[]	Yes	-	Array of order identifiers (UUIDs by default, or Shopify order IDs if use_shopify_order_id is true). For Shopify order IDs, provide the numeric portion of Shopify's order GID (e.g., for 'gid://shopify/Order/450789469', use '450789469').
`channels`	string[]	Yes	-	Notification channels to use: "email", "sms", "whatsapp". At least one channel is required to prevent accidental mass notifications.
`use_shopify_order_id`	boolean	No	false	Set to 'true' to look up orders using Shopify order IDs instead of UUIDs. Extract the number from Shopify's GID format (gid://shopify/Order/450789469 → 450789469) and use it in the order_ids array.
