How can I allow users to like posts using RESTapi

Product Support

AI-generated summary

A user, Maduka_Dilshan, is attempting to use the Discourse REST API to allow users to like posts. Despite having a Global API key with a global scope, they are receiving a “You are not permitted to view the requested resource” error when trying to like a post.

Maduka_Dilshan has already successfully implemented other API features such as topic creation, post creation, and bookmarking using the same API key and category settings.

Bas suggests that Maduka_Dilshan may need to use a User API key, but Maduka_Dilshan is unsure why this would be necessary for liking posts when other features work with the Global API key.

After some investigation, Maduka_Dilshan discovers that the issue may be due to the contentId being set to the correct post ID. However, it is later revealed that Maduka_Dilshan was trying to like their own post, which is not possible.

Maduka_Dilshan apologizes for the mistake and thanks the community for their help.

Hi all. I am pretty new to Discourse and checked All Site Settings (/admin/site_settings) section to find a matching option to allow any level of user to like posts using RESTapi

At the moment, all users can ( without public ) create topics, add replies etc. However a normal user (tl0, tl1 etc) cannot like to any post through the API ( But can like using the web panel )

Here’s is my category settings,

I’m using following code to add a like through API

  public async likeOrThrow(contentId: number, username: string) {
    try {
      this.overrideUsername(username);
      const res = await this.client.post(`post_actions.json`, {
        id: contentId,
        post_action_type_id: 2,
        flag_topic: false,
      });
      return res.data;
    } catch (error) {
      throw this.getException(error);
    } finally {
      this.resetUsername();
    }
  }

It throws,

You are not permitted to view the requested resource.

However if i log into the discourse as the user then that user can make a like,

So far I have integrated, Topic create, Post Create & Bookmark APIs with same API key with same categories and username and they work without any permission issue.

Could you please help me to figure out what im doing wrong here ? Let me know if more information is needed.

Thanks

I don’t know, but you can make your category settings easier using only everyone.

Hi @Bas thanks for the comment,

but why only for like ? I already implemented post creation, reply creation, bookmark add, remove with the Discourse API using Global key ( user level: all-users, scope: global )

Also tried to create a new Global API key, still getting the same error :frowning:

If the API key has global scope and valid for all users, then following API should work. isn’t it

Yes, this code looks good to me as well.

How / to what is contentId being set ? Is it the correct Post.id ?

Hi @RGJ

contentId is the post id and yes it is the correct post id.

With the following code, it logs,

      this.client.interceptors.request.use((config) => {
        Logger.log(`Request to ${config.url}`);
        Logger.log(`Headers: ${JSON.stringify(config.headers, null, 2)}`);
        Logger.log(`Body: ${JSON.stringify(config.data, null, 2)}`);
        return config;
      })

Log,

Oh snap, I think I found the issue. :grimacing:

When i did the test using web panel, i mistakenly choose a post from another user ( Same title as i was testing ) and it succeeded.

But when i test it using my system, i was trying to add a like to an own post.

Apologies for any inconvenience. I did not aware that it is not possible to like own posts.

Thanks and have a nice day.
