Event subscription view_href

Hi,   Is there any way of getting restapi.response_style=view to work with event subscription? Everytime a new message is posted I receive a HTTP-POST XML call on my server but I cannot construct a...

kjartan - Yes, indeed you can, the Lithium redirection engine works based on the ID as long as you have the type mentioned with it. e.g.

 

this thread over here, can be called with this URL as well and will redirect to the correct discussion

 

http://community.lithium.com/t5/xyz/123/td-p/184105

 

The red text needs to be same, which is the ID. In case of board, or category:

 

http://community.lithium.com/t5/xyz/bd-p/studio

http://community.lithium.com/t5/xyz/ct-p/Developer

 

You see, if you hit above URLs, they will take you to correct destination, as long as the ID and the type mentioned is correct.

Now you can construct a better looking URLs though, like http://community.lithium.com/t5/category/ct-p/Developer, http://community.lithium.com/t5/discussion/123/td-p/184105, http://community.lithium.com/t5/board/bd-p/studio

 

Though you'll need to be slightly vary in case you have same board and category ID. I hope this helps.

    Can you pls. add the view_href on the message event payload instead?

      Hi Joy_lim, 

      An alternate solution is you can add view_href and some more fields if you want in the message payload by creating a new endpoint and give the callback URL as your new endpoint URL instead of your service while registering the message event subscription.

      /restapi/vc/events/subscriptions/events/name/MessageCreate/subscribe?restapi.response_style=view&event.callback_url=endpoint_url

      Next, in the lithium endpoint parse the message object and get the message id and make lithium message API call by passing that message id to fetch complete message data and pass to your service http://mywebsite.com/


      Example: Make message API call in the endpoint to fetch complete message data and pass to your service
      https://community.com/restapi/vc/messages/id/1?restapi.response_style=view

      Thanks,
      Imtiaz

        Hi Imtiaz,

        Sounds like a workaround to me than a solution. Comparing these two approaches:

        1. Community adding a field, view_href, to the payload 

        vs. 

        1. Community Client creating an endpoint for the message event callback

        2. service (exposed by the endpoint) parsing the message id and making a Community API to retrieve message ID

        3. service making a callback to the client app passing the view href

         

        It sounds like it makes more sense to have it done on the Community side rather than having all clients of Community do those steps just to get that one attribute.
