[image] Akki9326: there is no settings like 'Minimum number of tags required in a topic". The setting is located in the “settings” tab for each specific category (the same place that you edit the category name).

See: [image] Reverse engineer the Discourse API Integrations Discourse is backed by a complete JSON api. Anything you can do on the site you can also do using the JSON api. The API is documented at docs.discourse.org. You can also use the discourse_api Ruby gem as a client library. However, not every endpoint is documented. To determine how to do something with the JSON API here are some steps you can follow. Example: recategorize a topic. Go to a topic and start editing a category: [image] Open Chrome dev tools, switch to the Network tab, select … Attempt to change tags on a topic, looks at the param.

Thanks for your replies. But we are also getting 500 error code while creating topic from discourse portal.

Hi @Akki9326, it looks like we have a bug here. To work around it for now, open up the preferences for the category, and set the “Minimum number of tags required in a topic” setting to zero. We will look at getting this fixed so it can’t happen in the future.

Thank @david for your reply. but there is no settings like 'Minimum number of tags required in a topic". for your info: we are able to create a topic in other categories but error occurs on one specific category only named “CFO-Members”. we are able to create same topic in other categories. Admin can create topic in that category (CFO-Members). it would be greate for us if can you suggest any work around for the same.

Thanks @david its works. :slight_smile:

For future reference, this is now fixed thanks to @maja https://github.com/discourse/discourse/commit/4a8f21d38743a0a6b2a161889e335581248583b9

does discourse need X-CSRF-TOKEN?
if we pass “api key”. bcz we are sending api key in our request still it shows "Can’t verify CSRF token authentiity".
