# Liking Posts

>  

Likes signal appreciation and enhance content visibility, triggering incremental rewards in Sage Protocol.

**React Hook Example for Liking Posts:**

```typescript theme={null}
import { usePost } from '@sageprotocol/sdk/react';
import { useWallet } from '@suiet/wallet-kit';

function LikePost({ authorSharedUserId, postId, ownedUserId }) {
  const { like } = usePost();
  const { account, signAndExecuteTransaction } = useWallet();

  async function handleLike() {
    const result = await like({
      amounts: [0, 0],                         // Required protocol fees
      appId: 'your-app-id',                    // Explicitly required application ID
      network: 'testnet',                      // 'testnet' or 'mainnet'
      authorSharedUserId,                      // Original post author's shared user ID
      postId,                                  // ID of the post to like
      ownedUserId,                             // Liker’s owned user ID
      self: account.address                    // Liker’s wallet address
    });

    if (result.ok) {
      await signAndExecuteTransaction({ transaction: result.transaction });
      console.log("Post liked successfully!");
    } else {
      console.error("Error liking post:", result.err);
    }
  }

  return <button onClick={handleLike}>Like Post</button>;
}

export default LikePost;
```

  ```javascript theme={null}
  import { SageClient } from '@sageprotocol/sdk';

  const sageClient = new SageClient({
    appId: 'your-app-id',                     // Required application ID
    channelRegistryId: 'your-registry-id',    // Required channel registry ID
    network: 'testnet'                        // 'testnet' or 'mainnet'
  });

  await sageClient.initialize();

  async function likePost(authorSharedUserId, postId, ownedUserId, walletAddress) {
    const result = await sageClient.likePost({
      amounts: [0, 0],                        // Required protocol fees
      authorSharedUserId,                     // Original post author's shared user ID
      postId,                                 // ID of the post to like
      ownedUserId,                            // Liker’s owned user ID
      self: walletAddress                     // Liker’s wallet address
    });

    if (result.ok) {
      await signAndExecuteTransaction({ transaction: result.transaction });
      console.log("Post liked successfully!");
    } else {
      console.error("Error liking post:", result.err);
    }
  }

  likePost('author-shared-user-id', 'target-post-id', 'your-owned-user-id', walletAddress);

## Important Notes

* **Required Parameters**: Inclusion of `amounts`, `appId`, `network`, `authorSharedUserId`, `postId`, `ownedUserId`, and `self`.
* **Reward Mechanism**: Likes enhance content visibility and trigger incremental rewards.
* **Transaction Execution**: All transactions must be signed and executed via the user's connected wallets.
