I've been following this thread and haven't yet got this to work.
Same issue / question - we want to make it easy for a user to subscribe to the message or perhaps the thread.
I've explored using the API... but consistently get a 501 errorr code when I use the POST method.
For example:
<form action="https://community.xxx.com/restapi/vc/boards/id/tips_and_tricks /subscriptions/users/self/add/email" method="post"><input type="submit"> <!-- Press this button to submit form --></form>
<response status="error">
<error code="501">
<message>
Unknown path element at node 'node_subscription_context.users.self.add'.
</message>
</error>
</response>
I get the same result for:
<form action="https://community.xxx.com/restapi/vc/threads/id/1615100/subscriptions/users/self/add/email" method="post"><input type="submit"> <!-- Press this button to submit form --></form>
Any ideas or feedback?
Thanks
John
