Remove Reaction

Remove a reaction from a post or comment. The backend uses api/Post/{postId}/reactions for posts; comment reaction removal may use api/Comment or a dedicated Reaction endpoint.

Endpoints

Post reaction

DELETE /api/Post/{postId}/reactions

Comment reaction

DELETE /api/Comment/{commentId}/reactions

(or equivalent Reaction API if implemented)

Authentication: Required

Path Parameters

Parameter	Type	Required	Description
postId	GUID	Post	Post ID (for post reactions)
commentId	string	Comment	Comment ID (for comment reactions)

Response

Success (200 OK)

{
  "success": true,
  "message": "Reaction removed successfully"
}

Error (404 Not Found)

{
  "success": false,
  "error": {
    "code": "REACTION_NOT_FOUND",
    "message": "No reaction found"
  }
}

Example

// Remove reaction from post
const response = await fetch(`http://localhost:5000/api/Post/${postId}/reactions`, {
  method: 'DELETE',
  headers: { 'Authorization': `Bearer ${token}` }
});

// Remove reaction from comment
const response = await fetch(`http://localhost:5000/api/Comment/${commentId}/reactions`, {
  method: 'DELETE',
  headers: { 'Authorization': `Bearer ${token}` }
});

Notes

• Only the user who created the reaction can remove it
• Removing a reaction updates the reaction counts immediately
• No error is returned if the reaction doesn't exist (idempotent)

Next Steps

• Add Reaction
