[NV-438] - Add payload content to notification object

[novubot]

Why?

After triggering an event and passing a payload object to it, the payload object is never saved on the message entity returned by the notifications API specifically for the notification center usecase.

What?

Persist the payload object inside the generated Notification Message for the channel including the original payload object sent by the API Users.

Where?

The unit responsible for creating the notification message is located inside the trigger-event.usecase.ts file inside the @novu/api package.

Done definition

• e2e test for the trigger event asserting the created message to contain the payload object when returned by the API.

@scopsy This will work for the payload. I just wanted to draw your attention to one issue which m facing. I will share the use case for this.

Scenario
Suppose we are sending notification for invite and we render two button for accept and reject. once we accept or reject the invite i want the buttons to be removed from notification. We can achieve this if we can change the payload part.

Is there any way we can update the specific notification payload?? Using some api or hooks??

@scopsy can I take this up?

[scopsy]

Sure @meehawk! Assigned you, let me know if you need any help.

[iampearceman]

@meehawk Hey! How is it going with adding the payload? Could you maybe give an ETA?
We thought about adding it to our next release

[scopsy]

Hi @meehawk we really want to push this ticket in the upcoming version since it's blocking a lot of our users for some usecases. Assigning @djabarovgeorge for this one 🙏

Really appreciate your help regardless!

[scopsy]

Merged in #725

[scopsy]

@singhgulshan we have merged this and will deploy soon, regarding the option to update the payload object with API we are planning to add this support in v0.6.0 in the next couple of weeks. Will update you on it.

[singhgulshan]

@scopsy can we update the same in documentation, so that it is easy for us to integrate payload specific changes?

[scopsy]

Hi @singhgulshan i've added the interface of IMessage to the docs. You can checkout the payload property: https://docs.novu.co/notification-center/react-components#the-notification-imessage-model

[singhgulshan]

@scopsy After updating @novu/notification-center to version 0.9.1. I'am not able to use IMessage interface. it says IMessage is not exported. Is this expected behaviour?? As i was using IMessage to customize my notification, so a quick solution would be a great help.

[djabarovgeorge]

Hey @singhgulshan I see the problem, shortly I will create a PR to fix it.
Thanks for raising it up! 👍🏻

[singhgulshan]

@djabarovgeorge Any ETA for this fix release?

[scopsy]

@scopsy the IMessages export should be available in 0.9.2 later today. 🙏

[scopsy]

@singhgulshan could you try upgrading the @novu/notification-center to v0.9.2 please?

[singhgulshan]

@scopsy It working fine now. Exports are available. Thanks.
