Like/Unlike a post returns 404

I am trying to like/unlike a post via API but it returns 404, “errors”:[“The requested URL or resource could not be found.”] and sometimes it executes successfully. What could be the possible reason for this?

I am making a HTTP call from Node.js with following data:

let form = {
    post_action_type_id: 2

and with following options :

{ hostname: '',
  path: '/post_actions/85815',
  method: 'DELETE',
  timeout: 3000,
   { 'Content-Type': 'application/x-www-form-urlencoded',
     'Content-Length': 21,
     Accept: 'application/json',
     'Api-Key': '12345678909876543212345678987654323456789',
     'Api-Username': '113225072183895994023' } }

Did you tried the same by using Postman?

I think I got the issue. Somehow only unlike Post is being called from my code and that’s why its returning 404. Thanks for the reply @fzngagan.

Yes. Are you sending the request always using DELETE method?
Its only for unliking. For liking, you need to send the request with POST method.
