Here you go! https://community.nodebb.org/topic/9447/howto-inject-hidden-data-into-composer/8 This should get you started. You'll need to edit the composer.tpl, or inject html at composer load, checking if the post is a new topic.

@frgilb said in Publish content/post from other apps?: @deha: I agree, with the write api plugin you should be able to solve your problem. There is even a python library available: https://pypi.python.org/pypi/pynodebb/. It is quite old but still works with up to date nodebb. Unfortunately, not all api calls are yet implemented, but it is easy (and quite obvious) to extend it. @baris said in Publish content/post from other apps?: Take a look at https://github.com/NodeBB/nodebb-plugin-write-api Thanks, helpful.
