What does this endpoint do?

This endpoint is intended to retrieve a list of subscriptions linked to the requested accountId.

The response will follow this structure:

• id: The unique identifier for the subscription.
• entityType: The type of callback to which the subscription is linked.
• notificationTo: The target for notifications from the callback.
• notificationType: The type of notification that will be sent.

It's important to remember to check the subscription with this endpoint to verify if the subscription is functional and correctly bind before starting the notification proccess and after any failure with notification flow.
