# Vindicia Internal Notes for Subscribe 2022.04 Release

Production Release Date: April 26, 2022

**Parent topic:**[Vindicia MarketONE Subscribe - 2022.04 Release Notes](2022.04_tp_subscribeReleaseNotes)

## Subscribe Features

### Push 2.0 - Replay Push Notifications on Demand

**In this release, Push 2.0 Replay Service, both Microservice and Portal 1 updates, are deployed in both Staging and Production for internal use.**

Push Notifications update merchants of the billing events as they occur.

In this release, the following capabilities are extended to Subscribe Push 2.0:

* Subscribe stores push messages along with the HTTP status code returned by the Merchant's webhook listener when delivery is attempted.
* It also tracks delivery success or failure.

Merchants can request message resubmission (replay) to their webhook listeners through Vindicia Client Technical Support.

Notifications can be replayed by:

* a specific message id
* a date range
* push event class and /or billing event
* specific Merchant identifier for a Push Class object (such as Subscription, Transaction, or Account)

**Note:** Push notifications can be replayed within 180 days of the triggering billing event to the merchant listener regardless of their previous delivery status.

For more details about this new capability, see [Push 2.0 Replay Messages in the wiki](https://wiki.corp.aws.vindicia.com/x/PQPGB).

For details on how to replay messages, see [the how to article in the wiki](https://wiki.corp.aws.vindicia.com/x/mIFSBQ).
