Eshopbox has a readily available integration with Exotel and Meta for sending SMS and WhatsApp customer notifications, respectively.
However, if you want to want to use any third-party app for sending customer notifications, you can do so via Webhooks.
Eshopbox will push real-time orders and return status to the webhook URL provided from your end. You can use these updates to trigger customer notifications. Learn how to track status using webhooks.
