While the user is on the hosted payments page the only way to get updates on payments is to process invoice webhooks. This will need to be done by a service you create and host that can receive and process the webhooks as well as make relevant changes to third party platforms that require status changes when a payment succeeds or fails.
Before being able to process webhooks you will need to create a webhook via the Merchant management section of the application. Here you can specify the URL the webhook will be sent to as well as an optional secret for added security. This will be added to the Authorization header like so: “Authorization: Secret YOUR_SECRET”.
After being set up a Webhook will be sent each time the Invoice has a Status change.
Example Webhook:

The most relevant field is the status field. On successful payment this will be updated to the paid state. Once your service receives a webhook with the paid status any orders made by the user can be completed on your third party e-commerce platform.
Another new field is the payment_processor_quotes array. This will contain a list of methods chosen by the user to make the payment. It can be used to check what currencies your users are paying or if they over/underpaid and by what amount.
