Hi!,
How can we add a flag to a post, and also remove the flag of the post using the discourse functions?
Hi,
Yes, you can! Following Reverse engineer the Discourse API, you can figure out how to do it.
In your case, it’s a POST request to /post_actions, with the following possible payload:
| field | descritpion |
|---|---|
id |
The post ID |
post_action_type_id |
The post action type ID |
message |
Message used with notify_user and notify_moderators actions types |
is_warning |
Whether you flag a topic |
take_action |
Whether to agree with the flag and hide the post immediately |
queue_for_review |
Whether to queue immediately for review |
flag_topic |
Whether you flag a topic |
| action type | ID |
|---|---|
off_topic |
3 |
inappropriate |
4 |
spam |
6 |
notify_user |
7 |
notify_moderators |
8 |
To delete a flag, you can send a DELETE request to /post_actions/<post_id> and as payload, post_action_type_id.
Hope that helps!

Can I use it in developing a plugin, and is there any other function to achieve this?
